Plant Growth Hormones Extracted from Fungus and Fish
The plant growth hormones extracted from a fungus and a fish are respectively Gibberellin and Kinetin. Let's understand each of these hormones in detail.
Gibberellins
Gibberellins are plant hormones that promote stem elongation, seed germination, and flowering. They are extracted from the fungus Gibberella fujikuroi. Some of the important functions of Gibberellins include:
- Stimulating stem elongation by increasing the internode length.
- Promoting seed germination by breaking down the dormancy of seeds.
- Inducing flowering by promoting the development of reproductive organs.
Kinetin
Kinetin is a plant hormone that promotes cell division and delays senescence (aging) in plants. It is extracted from fish scales or other sources. Some of the important functions of Kinetin include:
- Stimulating cell division and growth in plants.
- Delaying the aging process in plants by preventing the breakdown of chlorophyll and other cellular components.
- Promoting the formation of lateral buds and shoots in plants.
Conclusion
In conclusion, the plant growth hormones extracted from a fungus and a fish are Gibberellin and Kinetin respectively. Gibberellins promote stem elongation, seed germination, and flowering while Kinetin promotes cell division and delays senescence in plants.
