Plant Growth And Development Question 2
Question: Spraying of which of the following phytohormone on juvenile conifers helps in hastening the maturity period, that leads to early seed production?
(1) Indole-3-butyric Acid
(2) Gibberellic Acid
(3) Zeatin
(4) Abscisic Acid
Show Answer
Answer: (2) Gibberellic Acid
Explaination-
The phytohormone that, when sprayed on juvenile conifers, helps hasten the maturity period and leads to early seed production is Gibberellic Acid. Gibberellic Acid is a plant hormone that plays a significant role in promoting stem elongation, seed germination, and flowering. By applying Gibberellic Acid to juvenile conifers, the growth and development processes can be accelerated, leading to earlier maturity and seed production.
