Growth stage of rice plant(水稻生长阶段 全英文版)
植物生长的5个过程英文

植物生长的5个过程英文5 Processes of Plant GrowthPlants are living organisms that undergo various processes to grow and develop. Here are five key processes involved in plant growth:1. Germination - This is the process where a seed begins to grow into a new plant. It starts when the seed absorbs water and the embryo inside the seed starts to swell and break through the seed coat. The embryo then starts to grow roots, shoots, and leaves.2. Photosynthesis - This is the process where plants convert light energy from the sun into chemical energy to fuel their growth. Chlorophyll, a pigment found in plant cells, captures the light energy and uses it to create glucose (sugar) from water and carbon dioxide. This process also produces oxygen as a byproduct.3. Transpiration - This is the process where plants lose water through tiny pores on their leaves called stomata. As water evaporates from the leaves, it creates a suction that pulls more water up from the roots. This process helps to transport nutrients and minerals from the soil to other parts of the plant.4. Cell division - This is the process where new cells are created to help the plant grow. As the plant grows, it needs more cells to accommodate its increasing size. Cell division also helps repair any damage the plant may have sustained.5. Pollination - This is the process where pollen from the male part of a flower (the stamen) is transferred to the female part (the pistil) to fertilize the plant. This process is essential for the plant to produce seeds and reproduce.In conclusion, plant growth is a complex and fascinating process that involves a combination of physical, chemical, and biological reactions. Understanding these processes is crucial for farmers, gardeners, and anyone who wants to cultivate healthy plants.。

植物的生长过程作文英语The Journey of a Plant's Growth.The genesis of a plant's life is an astounding display of nature's wonders. It begins with a tiny seed, often invisible to the naked eye, carrying within it thepotential for growth and transformation. This seed, hidden beneath the soil's surface, is the first chapter in a remarkable tale of resilience and adaptability.The soil, rich in nutrients and microorganisms, provides the perfect incubator for the seed's germination. As the seed absorbs water and sunlight, it begins to swell, and eventually, a small crack appears on its surface. This crack is the gateway to a new life, as the seed's embryonic roots and shoot push their way out, seeking sustenance and light.The roots, which are the plant's lifeline, grow downwards, penetrating the soil in search of water andminerals. Simultaneously, the shoot, which will become the plant's stem, emerges upwards, breaking through the soil's surface and reaching towards the sun. This upward thrust is a powerful symbol of life's determination to thrive, defying gravity and pushing through obstacles.As the plant grows taller, its stem elongates, and leaves begin to unfurl. These leaves are the plant's solar panels, converting sunlight into energy through the process of photosynthesis. The chlorophyll in the leaves traps the sun's rays, using them to split water molecules into oxygen and hydrogen. The hydrogen is then combined with carbon dioxide from the air, creating glucose, which serves as the plant's fuel.As the plant matures, it goes through various stages of growth, each marked by distinct changes in its appearance and structure. From the delicate sprout to the robust adult plant, its form and function evolve to meet the demands of its environment. Whether it's a towering tree or a low-lying herb, each plant has a unique growth pattern that reflects its adaptation to its surroundings.Moreover, plants are not static beings. They interact constantly with their environment, responding to changes in light, temperature, and soil conditions. They flex and bend in the wind, adjusting their posture to maximize sunlight exposure. They send out roots in search of water and nutrients, and when faced with drought or other environmental stresses, they go through physiological changes that allow them to survive.The plant's journey doesn't end with its maturity. It continues through reproduction, when flowers appear, attracting pollinators that carry the plant's genetic material to other plants, ensuring its survival and propagation. The fruits and seeds that follow are theplant's legacy, carrying within them the potential for a new generation of plants to thrive and flourish.In conclusion, the growth process of a plant is a marvelous display of nature's genius. It's a testament to resilience, adaptability, and the power of life itself. From the smallest seed to the tallest tree, the plant'sjourney is a continuous dance with its environment, a dance that is as old as life itself and as vital to our own existence.。
植物生长过程小报英语

植物生长过程小报英语Plant Growth Process。
Plants are living things that grow from tiny seeds into mature plants. The growth process in plants can be divided into three main stages: germination, vegetative growth, and reproductive growth.Germination: This is the first stage in the growth process of plants. When a seed is planted in soil, it absorbs water and oxygen, which triggers a process called germination. During germination, the seed coat breaks open, and the seedlings emerge from the soil. The seedling then develops a root system, which helps it to absorb water and nutrients from the soil.Vegetative growth: The second stage of plant growth is vegetative growth. During this stage, the plant develops leaves and stems and grows in size. The leaves are responsible for photosynthesis, a process that produces food for the plant. The plant continues to develop roots to support its growth and to absorb nutrients and water.Reproductive growth: The final stage of plant growth is reproductive growth. During this stage, the plant produces flowers, fruits, and seeds. Flowers are the reproductive organs of the plant. They are responsible for producing pollen, which then fertilizes the ovules in the plant. The fertilized ovulesthen develop into fruits and seeds, which can be used for propagation.Finally, it is important to note that the growth process in plants is affected by various factors such as temperature, light, soil quality, and water availability. By providing favorable conditions for plant growth, we can ensure that they growhealthily and produce good yields.。

英语写植物的生长过程小学作文Plants, the green wonders of nature, undergo a remarkable journey from a mere seed to a vibrant, growing organism. Let's delve into the fascinating world of plant growth and understand the stages involved in this miraculous process.**Stage 1: The Seed**It all begins with a seed, a small bundle of potential energy. Inside the seed, there is an embryo, which is the young plant waiting to sprout. The seed also contains food reserves that will nourish the embryo during its early growth stages.**Stage 2: Germination**When the seed is exposed to the right conditions - warmth, moisture, and light - it starts to germinate. This is when the embryo within the seed starts to grow and develop into a seedling. The seed's hard outer coating begins to crack open, and a small shoot emerges.**Stage 3: Growth**As the seedling grows, it produces roots to anchoritself in the soil and absorb water and nutrients. Simultaneously, it produces a stem and leaves to capture sunlight for photosynthesis. The plant now starts to grow taller and stronger, with more leaves appearing on the stem. **Stage 4: Flowering**As the plant matures, it reaches a stage called flowering. This is when the plant produces flowers, which are its reproductive organs. Flowers attract pollinatorslike insects or birds, who help in the transfer of pollen from one flower to another.**Stage 5: Fruiting and Seed Dispersal**After pollination, the flowers develop into fruits, which contain seeds. These seeds are then dispersed by various means, such as wind, water, or animals, to startthe growth cycle all over again.The journey of plant growth is not just about the physical changes but also about the interaction with its environment. Plants need sunlight, water, soil, and air to grow and thrive. They also play a crucial role inmaintaining the balance of our ecosystem by providing oxygen, absorbing carbon dioxide, and supporting a diverse array of wildlife.Understanding the growth process of plants helps us appreciate their resilience and adaptability. From a mere seed, plants transform into beautiful, functioning organisms that add color and life to our world.

英语植物生长的过程作文

英语植物生长的过程作文The Process of Plant Growth。
Plants are an essential part of our ecosystem, providing oxygen, food, and beauty to the world. The process of plant growth is a fascinating and complex one, involving a series of stages and factors that contribute to the development of a seed into a mature plant. In this essay, we will explore the various stages of plant growth and the factors that influence it.The first stage of plant growth is germination. This is when a seed begins to sprout and grow into a seedling. Germination is triggered by the right combination of water, oxygen, and temperature. When a seed is planted in soil, it absorbs water and swells, causing the seed coat to crack open. This allows oxygen to enter the seed, which is essential for the process of germination. The temperature also plays a crucial role in germination, as most seeds require a certain range of temperatures to start growing.Once the seed has germinated, it begins to develop roots. The roots are responsible for absorbing water and nutrients from the soil, which are essential for theplant's growth. As the root system develops, it anchors the plant in the soil and provides support for the growing plant. The roots also play a role in the process of photosynthesis, as they transport water and nutrients to the leaves, where the process takes place.The next stage of plant growth is the development of the stem and leaves. The stem provides support for the plant and allows it to transport water and nutrients from the roots to the leaves. The leaves are the primary site of photosynthesis, where the plant converts sunlight into energy. This process is essential for the plant's growth and survival, as it provides the plant with the energy it needs to grow and reproduce.As the plant continues to grow, it begins to produce flowers. The production of flowers is a crucial stage in the life cycle of a plant, as it is the means by which theplant reproduces. The flowers contain the plant's reproductive organs, which are essential for the production of seeds. Once the flowers have been pollinated, they develop into fruits, which contain the seeds of the plant.The final stage of plant growth is the maturation of the plant. This is when the plant reaches its full size and begins to produce seeds. The seeds are essential for the survival of the plant species, as they allow the plant to reproduce and spread its genes to future generations.There are several factors that influence the growth of plants. These include the availability of water, sunlight, nutrients, and temperature. Water is essential for the process of photosynthesis and the transport of nutrients within the plant. Sunlight is also crucial for photosynthesis, as it provides the energy that the plant needs to grow. Nutrients, such as nitrogen, phosphorus, and potassium, are essential for the plant's growth and development. Finally, temperature plays a crucial role in plant growth, as it affects the rate of photosynthesis and the overall growth of the plant.In conclusion, the process of plant growth is a complex and fascinating one, involving a series of stages and factors that contribute to the development of a seed into a mature plant. From germination to maturation, the growth of a plant is influenced by a variety of factors, including water, sunlight, nutrients, and temperature. Understanding the process of plant growth is essential for thecultivation of healthy and productive plants, and it is a fascinating subject that continues to be studied and explored by scientists and gardeners alike.。

The information presented is based on the data and characteristics of IR64, a modern, high-yielding, semidwarf variety, but applies generally to other rice varieties.This reference guide will enable you to:•recognize the 3 basic growth phases of the rice plant and the stages of development in each phase.•identify the growth stages of a rice plant according to a 0-9 numerical scale. Each number in the scale corresponds to a specific growth stage.•explain the specific physical changes in a growing rice plant.Three growth phasesThe growth of the rice plant is divided into three phases:1. vegetative (germination to panicle initiation);2. reproductive (panicle initiation to flowering); and3. ripening (flowering to mature grain)•In the tropics, the reproductive phase is about 35 days and the ripening phase is about 30 days.•The differences in growth duration are determined by changes in the length of the vegetative phase.•For example, IR64 which matures in 110 days has a 45-day vegetative phase, whereas IR8 which matures in 130 days has a 65-day vegetative phase.Growth stages 0-9These 3 growth phases consist of a series of 10 distinct stages. These stages are numbered and described as follows:Stage 0 is from germination to emergence:Stage 1 is called seedling:Stage 2, tillering:and Stage 3 is stem elongation:These first 4 stages make up the vegetative phase, the first phase of rice plant growth. Stage 4 is panicle initiation to booting:Stage 5 is heading or panicle exsertion:and Stage 6 is flowering:Stages 4, 5, and 6 constitute the reproductive phase, the second phase of rice growth. Stage 7 is the milk grain stage:Stage 8, the dough grain stage:and Stage 9, the mature grain stage:Stages 7 through 9 correspond to the ripening phase, the last phase in the development of the rice plant.Vegetative PhaseStage 0 - Germination to emergenceSeeds are usually pregerminated by soaking for 24 hours and incubating for another 24 hours. After pregermination the radicle and plumule protrude through the hull.By the second or third day after seeding in the seedbed, the first leaf breaks through the coleoptile.The end of stage 0 shows the emerged primary leaf still curled and an elongated radicle.Stage 1 - SeedlingThe seedling stage starts right after emergence and lasts until just before the first tiller appears. During this stage, seminal roots and up to five leaves develop.As the seedling continues to grow, two more leaves develop. Leaves continue to develop at the rate of 1 every 3-4 days during the early stage.Secondary adventitious roots that form the permanent fibrous root system rapidly replace the temporary radicle and seminal roots.This is an 18-day-old seedling ready for transplanting. The seedling has 5 leaves and a rapidly developing root system.Stage 2 - TilleringThis stage extends from the appearance of the first tiller until the maximum tiller number is reached. Tillers emerge from the axiliary buds of the nodes and displace the leaf as they grow and develop.This seedling shows the position of the two primary tillers with respect to the main culm and its leaves.After emerging, the primary tillers give rise to secondary tillers. This occurs about 30 days after transplanting.The plant is now increasing in length and tillering very actively. Here is a field with plants at the early tillering stage. Note the tiller size and canopy development due to increased leafing and tiller development.Besides numerous primary and secondary tillers, new tertiary tillers arise from the secondary tillers as the plant grows longer and larger.By this stage, the tillers have multiplied to the point that it is difficult to pick out the main stem. Tillers continuously develop as the plant enters the next stage which is stem elongation.Stage 3 - Stem elongationThis stage may begin before panicle initiation or it may occur during the latter part of the tillering stage. Thus, there may be an overlap of stages 2 and 3.The tillers continue to increase in number and height, with no appreciable senescence of leaves noticeable. Ground cover and canopy formation by the growing plants have advanced.Growth duration is significantly related to stem elongation. Stem elongation is more in varieties with longer growth duration. In this respect, rice varieties can be categorized into two groups: the short-duration varieties which mature in 105-120 days and the long-duration varieties which mature in 150 days.In early-maturing semidwarfs like IR64, the fourth internode of the stem, below the point where the panicle emerges, elongates only from 2 to 4 cm before panicle initiation becomes visible. This slide shows stems which have been dissected to show the length of the fourth internode at the panicle initiation stage.Maximum tillering, stem elongation, and panicle initiation occur almost simultaneously inshort-duration varieties (105-120 days).In long-duration varieties (150 days), there is a so-called lag vegetative period during which maximum tillering occurs. This is followed by stem or internode elongation, and finally by panicle initiation.Reproductive PhaseStage 4 - Panicle initiation to bootingThe initiation of the panicle primordium at the tip of the growing shoot marks the start of the reproductive phase. The panicle primordium becomes visible to the naked eye about 10 days after initiation. At this stage, 3 leaves will still emerge before the panicle finally emerges.In short-duration varieties, the panicle becomes visible as a white feathery cone 1.0-1.5 mm long. It occurs first in the main culm and then in tillers where it emerges in uneven pattern. It can be seen by dissecting the stem.As the panicle continues to develop, the spikelets become distinguishable.The young panicle increases in size and its upward extension inside the flag leaf sheath causes the leaf sheath t bulge. This bulging of the flag leaf sheath is called booting.Booting is most likely to occur first in the main culm.At booting, senescence (aging and dying) of leaves and nonbearing tillers are noticeable at the base of the plant.Stage 5 - HeadingAlso known as the panicle exsertion stage. Heading is marked by the emergence of the panicle tip from the flag leaf sheath. The panicle continues to emerge until it partially or completely protrudes from the sheath.FloweringStage 6 is called flowering. It begins when anthers protrude from the spikelet and then fertilization takes place.At flowering, the florets open, the anthers protrude from the flower glumes because of stamen elongation, and the pollen is shed. The florets then close.The pollen falls on the pistil, thereby fertilizing the egg. The pistil is the feathery structure through which the pollen tube of the germinating pollen (round, dark structures in this illustration) will extend into the ovary.The flowering process continues until most of the spikelets in the panicle are in bloom. From left to right, this frame shows anthesis or flowering at the top of the panicle, 1st day after heading; anthesis at the middle of the panicle, 2nd day after heading; anthesis at the lower third of the panicle, 3rd day after heading.Flowering occurs a day after heading. Generally, the florets open in the morning. It takes about 7 days for all spikelets in a panicle to open. At flowering, 3-5 leaves are still active.The tillers of this rice plant have been separated at the start of flowering and grouped into bearing and nonbearing tillers.Ripening PhaseStage 7 - Milk grain stageThe last 3 stages of growth, stages 7, 8, and 9 comprise the ripening phase. Stage 7. Milk grain stageIn this stage, the grain has begun to fill with a milky material.The grain starts to fill with a white, milky liquid, which can be squeezed out by pressing the grain between the fingers.The panicle looks green and starts to bend. Senescence at the base of the tillers is progressing. The flag leaves and the two lower leaves are green.Stage 8 - Dough grain stageDuring this stage, the milky portion of the grain first turns into a soft dough and later into a hard dough.The grains in the panicle begin to change from green to yellow. Senescence of tillers and leaves is noticeable.The field starts to look yellowish. As the panicle turns yellow, the last two remaining leaves of each tiller begin to dry at the tips.Stage 9 - Mature grain stageThe individual grain is mature, fully developed, hard, and has turned yellow.This slide shows rice plants at the mature grain stage. Ninety to one hundred percent of the filled grains have turned yellow and hard.The upper leaves are now drying rapidly although the leaves of some varieties remain green. A considerable amount of dead leaves accumulate at the base of the plant.Print versionThe manual for Growth Stages of the Rice Plant may also be completely printed, provided you have a printer attached to your computer and Microsoft Word.
