Question

difference between hybridization and emasculation

Answer 1

Pollination is the process on which plants depend to transfer pollen grains from anther to stigma. It can be either cross-pollination or self-pollination, and their results vary. All pollinations will not lead to a successful fertilization because of a successful fertilization pistil of a flower has to recognize its right pollen of same species. In other words, pollen and stigma should be compatible. Incompatibility may lead to rejection of pollen. This situation is undesirable, especially in commercial crop production. Thus, artificial hybridization was developed.

Answer 2

We know hybridization is the method of selective breeding. Thus, anthers have to be removed from a bisexual flower before they release pollen grains. This step of removal of anther using forceps is termed as emasculation. In the case of unisexual flowers, this step is not necessary.
