1. Gibberellins promote stem elongation by stimulating cell division and elongation in the stem tissues. This helps plants to grow taller and reach sunlight for photosynthesis.
2. Gibberellins promote seed germination by breaking seed dormancy and stimulating the synthesis of enzymes that break down stored nutrients in the seed.
3. Gibberellins regulate flowering by promoting the development of floral organs and inducing flowering in some plants.
4. Gibberellins regulate fruit development by promoting cell division and elongation in the fruit tissues, leading to larger and juicier fruits.
5. Gibberellins also play a role in leaf expansion, root growth, and other developmental processes in plants.
