Question

describe the out breeding devices that prevent the autogamy

Answer 1

Answer:

Repeated self pollination leads to inbreeding depression. Methods ordevices which favor cross pollination are known as outbreeding devices. Plants have developed methods to prevent self pollination. Autogamy is prevented by following ways: Pollen release and stigma receptivity not coordinated.

word autogamy mean self fertilization. this is a special type of self pollination in which an intersexual or top flower is pollinated through its own pollen. Autogamy is only possible when anther and stigma are close to each other and which has synchrony in pollen release and stigma respectively. It is frequently meet in unicellular organisms such as protozoan, protist.

autogamy in plant :- the plant which is capable to fertilize themselves rather than hybridize with another plants.

Autogamy occurs by three method:-

Namely-homogamy
