Question

After fertilization which hormone helps ovary to become fruit?

Answer 1

After fertilization, the hormone that helps the ovary to become a fruit is called auxin. Auxin is a plant hormone that plays a critical role in many aspects of plant growth and development, including the formation of fruits. After fertilization, the developing embryo produces auxin, which is transported to the ovary. The auxin then stimulates the ovary to develop into a fruit, a process known as fruit set. The auxin hormone promotes cell division and enlargement in the ovary, causing it to grow and develop into a mature fruit.
Other hormones such as cytokinins, gibberellins, and abscisic acid also play important roles in fruit development and maturation, but auxin is primarily responsible for initiating fruit development after fertilization.
