Explanation:
plz make me as brainlist please
1. Elongation of genetically dwarf plants:
In higher plant is to stimulate the elongation of inter-nodal cells. miniature varieties of plants are often genetic mutants, which do not produce gibberellins. They can be made to grow to normal size by application of gibberellins.
2. Bolting and flowering in long-day plants:
They controlling a balance between internodes growth and leaf development.
3. Substitution of cold treatment:
Biennial plants flower only when they receive low temperature during winter season. Such plants would, however, flower after gibberellins treatment even if they do not receive suitable low temperature. Thus biennial plants can be made to flower in a single year by gibberellins treatment.
4. Breaking of dormancy:
They can effectively break the dormancy of potato tubers and winter buds of many trees. They also act as an antagonist to abscisic acid.
5. Parthenocarpy:
They are more effective than auxins in inducing parthenocarpy.
6. The hormone tried with leaf and root culture of digitalis, showed higher production of digoxin.
7. Spraying juvenile conifers with gibberellins hastens the maturity period, the leading to early seed production
8. Spraying sugarcane crop with gibberellins increase the length of the stem.
