Identify the growth regulators that help to overcome the given physiological problems in a plant.

A) Withstand desiccation and other factors unfavourable for growth

B) Promotes female flowers in cucumber

C) Increase absorption surface

D) Rapid elongation in internodes

The growth regulators that help to overcome the given physiological problems in a plant are:

Abscisic acid (ABA): ABA is a growth regulator that helps plants to withstand desiccation and other factors unfavourable for growth. It is involved in regulating stomatal closure, which reduces water loss from the leaves. ABA also plays a role in seed dormancy and helps plants survive under conditions of drought, high salinity, and extreme temperatures.

Ethylene: Ethylene is a growth regulator that promotes female flowers in cucumber. It is a gaseous hormone that regulates a variety of physiological processes in plants, including fruit ripening, senescence, and response to stress. It also promotes root growth and root hair formation, thus helping the plants to increase their absorption surface. Ethylene promotes rapid internode/petiole elongation in deep water rice plants.
