Question

Which of the following effects of auxins is of wide application?

पर्याय

• induction of fruit development

• induction of root initiation

• prevention of abscission

• all of these

Answer 1

All of these

Explanation:

Auxins are widely used in agriculture and horticulture because of their versatile physiological effects on plant growth. They are widely used to induce root initiation in stem cuttings for rapid vegetative propagation and to stimulate parthenocarpy for seedless fruit development. Additionally, spraying dilute auxins effectively prevents the premature abscission (dropping) of young leaves and fruits before the harvest season, making all three options vital commercial applications.
