Plant hormone
Plant hormones (also known as phytohormones) are chemicals that regulate plant growth, which, in the UK, are termed 'plant growth substances'.
Plant hormones are signal molecules produced within the plant, and occur in extremely low concentrations. Hormones regulate cellular processes in targeted cells locally and, moved to other locations, in other functional part of the plant. Hormones also determine the formation of flowers, stems, leaves, the shedding of leaves, and the development and ripening of fruit. Plants, unlike animals, lack glands that produce and secrete hormones. Instead, each cell is capable of producing hormones. Plant hormones shape the plant, affecting seed growth, time of flowering, the sex of flowers, senescence of leaves, and fruits. They affect which tissues grow upward and which grow downward, leaf formation and stem growth, fruit development and ripening, plant longevity, and even plant death. Hormones are vital to plant growth, and, lacking them, plants would be mostly a mass of undifferentiated cells. So they are also known as growth factors or growth hormones. The term 'Phytohormone' was coined by Thimann in 1948.

Mechanisms of Plant Growth
We've gone over the various tiers of structure of a plant, from cells, to tissues, to organs and organ systems. Now it's time to better understand how plants grow. How to plants know when to grow? How do they know which direction to grow? All of this is regulated by plant hormones, which are signaling molecules, just like the ones that we have in our bodies, though they are totally different molecules than ours. Auxin, cytokinin, gibberellins, abscisic acid, and ethylene, what do these molecules do? What is gravitropism? What is phototropism? Let's learn all this and more!

Uses of Plant Hormones | Plants | Biology | FuseSchool In this video we are going to look at a few different ways in which plant hormones can be used. Plant growth hormones (auxins) can be used as selective weedkillers. The selective weedkillers contain growth hormones, that cause the weeds to grow really quickly. This means the weed is absorbing nutrients from the soil at a much higher rate, and so the weeds absorb the weedkiller in much larger quantities than beneficial plants. This can be used for getting rid of weeds without killing the grass, or thistles in a field without killing the crop. But they aren’t just good at killing plants. Gardeners use growth hormones to promote growth. They take cuttings of plants and dip the stalk end into rooting powder which contains growth hormo...

This means the weed is absorbing nutrients from the soil at a much higher rate, and so the weeds absorb the weedkiller in much larger quantities than beneficial plants. This can be used for getting rid of weeds without killing the grass, or thistles in a field without killing the crop.
But they aren’t just good at killing plants. Gardeners use growth hormones to promote growth. They take cuttings of plants and dip the stalk end into rooting powder which contains growth hormones. This makes stem cuttings quickly develop roots and establish as functioning plants.
Plant hormones can also be used in controlling fruit ripening. Some slow it down, and others speed it up. We can make use of this knowledge to inhibit hormones during transport so that the fruit does not ripen too quickly, or we can promote ripening when in the shops so it is in perfect condition for consumers. Bite into a banana, and you don’t expect seeds do you? Hormones sprayed onto flowers can stop seeds developing, leaving us with big, juicy, seedless fruits.
In nature, plants only germinate when conditions are ideal for growth. This is called seed dormancy and is controlled by hormones. We can use hormones and inhibitors to remove the dormancy of seeds, thus enabling us to germinate seeds at all times of the year.
We can also use these hormones to make plants grow bushier and make them flower at controlled times; exactly what you want if you are entering a flower show!
Ethylene is used to ripen fruit. Ethylene breaks down components of the cell walls to make them softer, and makes them sweeter by converting starches to sugars. Ever wondered why you are told to put unripe fruit next to ripe fruit? Ethylene is different to other hormones because it is an airborne gas, and works on a positive feedback loop. Start with a little ethylene, and this causes more to be released, which causes more to be released… and so on. Therefore promoting ripening in all ‘local’ fruit.

पौधों में हार्मोन
पादप हार्मोन शब्द स्टर्लिंग द्वारा दिया गया। पौधों में उसकी वृद्धि और विकास को नियंत्रित करने रासायनिक पदार्थों का समूह पादप हार्मोन कहलाता है। पादप हार्मोन को फाइटोहार्मोन भी कहते हैं।
एब्सीकिक एसिड, एथिलीन ,साइटोका़निन, आक्जिन और जिबरेलिन आदि पादप हार्मोन कहलाते हैं।

We've gone over the various tiers of structure of a plant, from cells, to tissues, to organs and organ systems. Now it's time to better understand how plants grow. How to plants know when to grow? How do they know which direction to grow? All of this is regulated by plant hormones, which are signaling molecules, just like the ones that we have in our bodies, though they are totally different molecules than ours. Auxin, cytokinin, gibberellins, abscisic acid, and ethylene, what do these molecules do? What is gravitropism? What is phototropism? Let's learn all this and more!

Uses of Plant Hormones | Plants | Biology | FuseSchool
In this video we are going to look at a few different ways in which plant hormones can be used.
Plant growth hormones (auxins) can be used as selective weedkillers. The selective weedkillers contain growth hormones, that cause the weeds to grow really quickly. This means the weed is absorbing nutrients from the soil at a much higher rate, and so the weeds absorb the weedkiller in much larger quantities than beneficial plants. This can be used for getting rid of weeds without killing the grass, or thistles in a field without killing the crop.
But they aren’t just good at killing plants. Gardeners use growth hormones to promote growth. They take cuttings of plants and dip the stalk end into rooting powder which contains growth hormones. This makes stem cuttings quickly develop roots and establish as functioning plants.
Plant hormones can also be used in controlling fruit ripening. Some slow it down, and others speed it up. We can make use of this knowledge to inhibit hormones during transport so that the fruit does not ripen too quickly, or we can promote ripening when in the shops so it is in perfect condition for consumers. Bite into a banana, and you don’t expect seeds do you? Hormones sprayed onto flowers can stop seeds developing, leaving us with big, juicy, seedless fruits.
In nature, plants only germinate when conditions are ideal for growth. This is called seed dormancy and is controlled by hormones. We can use hormones and inhibitors to remove the dormancy of seeds, thus enabling us to germinate seeds at all times of the year.
We can also use these hormones to make plants grow bushier and make them flower at controlled times; exactly what you want if you are entering a flower show!
Ethylene is used to ripen fruit. Ethylene breaks down components of the cell walls to make them softer, and makes them sweeter by converting starches to sugars. Ever wondered why you are told to put unripe fruit next to ripe fruit? Ethylene is different to other hormones because it is an airborne gas, and works on a positive feedback loop. Start with a little ethylene, and this causes more to be released, which causes more to be released… and so on. Therefore promoting ripening in all ‘local’ fruit.

Plant hormone
Plant hormones (also known as phytohormones) are chemicals that regulate plant growth, which, in the UK, are termed 'plant growth substances'.
Plant hormones are signal molecules produced within the plant, and occur in extremely low concentrations. Hormones regulate cellular processes in targeted cells locally and, moved to other locations, in other functional part of the plant. Hormones also determine the formation of flowers, stems, leaves, the shedding of leaves, and the development and ripening of fruit. Plants, unlike animals, lack glands that produce and secrete hormones. Instead, each cell is capable of producing hormones. Plant hormones shape the plant, affecting seed growth, time of flowering, the sex of flowers, senescence of leaves, and fruits. They affect which tissues grow upward and which grow downward, leaf formation and stem growth, fruit development and ripening, plant longevity, and even plant death. Hormones are vital to plant growth, and, lacking them, plants would be mostly a mass of undifferentiated cells. So they are also known as growth factors or growth hormones. The term 'Phytohormone' was coined by Thimann in 1948.
