Detailed explanation-1: -Final Answer: Auxins helps in preventing the premature falling of fruit and leaf at early stages. Q. Assertion: Auxins help to prevent fruit and leaf drop at early stages. Reason: Auxins promote the abscission of older mature leaves and fruits.
Detailed explanation-2: -Auxins is a plant hormone that is known to inhibit both premature leaf and fruit fall. Auxin postpones the abscission of young leaves and fruits.
Detailed explanation-3: -One way to slow down ripening is by lowering the temperature. Cold temperatures above freezing are usually used. Even though all fruit can be frozen, upon thawing many fruits lose their flavor and their texture and become very mushy.
