Open in App
Solution
The correct option is D Abscisic acid
Auxin is the plant growth hormone that promotes lengthening and coordinates with other growth hormones to regulate growth; it also causes apical dominance. Cytokinin is the plant growth hormone that promotes cell division in shoot apical meristem and differentiation in root apical meristem. It works antagonistically to auxin to balance the growth with development in the shoot and root apex. Gibberellins are responsible for stem elongation, breaking seed dormancy, mobilization of endosperm reserves as well as regulate sex determination, flower initiation and fruit set. Abscisic acid is a plant growth hormone involved in seed dormancy by suppressing seed germination and growth as well as in responses of plants to stress. This makes option D correct.
