Application of which chemical in the form of foliar spray at the beginning of flower bud development may improved drought resistance in pea

Answer: Option D

Application of Chlormequat chemical in the form of foliar spray at the beginning of flower bud development may improve drought resistance in pea.
Chlormequat is an organic compound used as a plant growth regulator.
Chlormequat has been called the most important inhibitor of gibberellin biosynthesis. It inhibits cell elongation, resulting in thicker stalks, which are sturdier, facilitating the harvesting of cereal crops. In exogenous application, it also improves drought resistance in some plants.
