As the axillary buds of pruned plants get sensitized to (d) IAA, it promotes branching.
Explanation:
- The hormones present in the plants play a vital role in the physical and biological mechanisms of the plants.
- The most important of them are ethylene, gibberellin, cytokinin, and auxin.
- Pruning is the process involved in horticulture in which the portion of the plant is removed.
- Many (yet not all) plant species have a prevailing apical meristem that produces IAA to stop or moderate the development of close by axillary meristems.
- Due to this a cone-molded plant that gets daylight unequally in such a manner that top layer receives more sunlight whereas the bottom layer is devoid of it.
- To override this problem pruning of the top apical meristem makes the cells to get sensitized with IAA and promotes branching.
- Thus it is inferred that option (d) is the correct answer for the given question.
