A farmer grows cucumber plants in his field. He wants to increase the number of female flowers in them. Which plant growth regulator can be applied to achieve this?
The plant growth regulator that can be applied to achieve this is ethylene (C2H4).
Plant Growth Regulators are produced in various parts of the plant. They control differentiation and development of various parts of the plants as well as has physiological effects on plants too.
Ethylene induces flowering so can be used to increase the number of female flowers in the cucumber plants. It selectively induces flowering of female plants suggesting a link between ethylene signalling and primordial anther specific DNA damage in female cucumber flowers.
