Assertion : Gibberellins induce flowering in long day plants. Reason : Genetically tall plant become dwarf by application of Gibberellin.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Application of GA can induce flowering in long day plants. It has no favourbale effect on size of flower and fruit in certain plants. The genetically dwarf plants can be made tall by application of GA.

How does gibberellins change the quality of an apple?
1 Make it sweeter
2 Elongate it in size
3 Improve its shape
4 2 and 3
Explanation:
Gibberellins have an ability to cause an increase in length of axis is used to increase the length of grapes stalks. Gibberellins, cause fruits like apple to elongate and improve its shape.

What change does GA bring in juvenile conifers?
1 Hastens maturity period and early seed production
2 Hastens germination period and early germination
3 Hastens dormancy period and early seed production
4 Lessens maturity period and early seed production
Explanation:
Spraying juvenile conifers with GAs hastens the maturity period, thus leading to early seed production.

Which one of the following is not an effect of gibberellin?
1 Increase the length of grapes stalks
2 Delay senescence of fruits
3 Induce dormancy
4 Increase the length of sugarcane stem
Explanation:
ABA (Abscisic acid) plays an important role in seed development, maturation and dormancy. By inducing dormancy, ABA helps seeds to withstand desiccation and other factors unfavourable for growth.
