Gibberellins Functions
The plant hormone is responsible for a variety of functions, as mentioned below:
- Seed Germination: Sunlight is a major component for germinating seeds of several species. In its absence, those seeds fail to germinate in time. However, the requirement of sunlight can be replaced by gibberellins, which can facilitate the fast germination of those seeds.
- Dormancy in Buds: Often buds are dormant i.e. they don’t grow due to several reasons (eg. lack of ideal conditions). Gibberellins can trigger the breaking of such dormancy in buds.
- Postponing aging: Gibberellins can postpone the senescence (aging) of leaves and other plant components, keeping them functioning and green for extended periods.
- Elongation of Stem: Gibberellins encourage cell proliferation and elongation in the internodes of the stem, which in turn promotes stem elongation. This has an impact on the plant’s total height and the distance between its branches and leaves.
- Development of Fruits: The phytohormones can heavily influence the size and growth of fruits. They may, in certain instances, cause the fruit to elongate and the reduction of seed production.
Gibberellins: Functions and Agricultural Applications
Gibberellins are important plant hormones that play a crucial role in various growth and developmental processes. These hormones, known for promoting stem elongation, seed germination, and flowering, are essential for optimal plant health. Understanding gibberellins can enhance agricultural practices by improving crop yield and quality. Explore into the functions and significance of gibberellins to uncover their impact on plant biology and agricultural advancements.
