Detailed explanation-1: -In order to increase the yield of sugarcane crop, which of the following plant growth regulators should be sprayed? The correct answer is (4) Gibberellins. This is because – Gibberellins shows bolting when gibberellin is sprayed on sugarcane crop, the length of the stem increases.

Detailed explanation-2: -Final answer: Gibberellins are sprayed on sugarcane stems to increase the yield.

Detailed explanation-3: -Spraying the sugarcane crop with gibberellins increases the length of stem and yield of sugarcane to as much as 26 tonnes/acre.

Detailed explanation-4: -Gibberellin spray in sugarcane induces the growth in the internodal area of the sugarcane plant.

Detailed explanation-5: -a. Increase yield of sugar cane: Giberellins (Spraying sugarcane crop with gibberellins increases the length of the stem and hence increases the yield of sugarcane by about 20 tonnes per acre). b. Promote lateral shoot growth: Cytokinins (These are generated in regions where rapid cell division occurs).
