How do plants avoid self-fertilization?

I have this bio essay due next week and I'm lost. I'm search all over the internet and the only point I can find is "self-incompatibility". I would like to write more. Can anyone suggest anything else?



Besides that, I want to know the biology term for the process where anter and stamen of a particular plant grows at different rates therefore avoiding self-fertilization.



Please and thank you in advance! :)

How do plants avoid self-fertilization?
You're using the wrong terminology.

Not self-fertilization or germination, but "self pollination".

Since self pollination is counterproductive to "hybrid vigor" and evolutionary change, plants have developed various ways to avoid this and encourage "cross pollination".

Couple I can think of off hand: The anther releases pollen before

the stigma is receptive (i.e.,before it matures) ; The stamens'

lengths are much shorter than the pistil so as to make it more difficult for pollen grains to settle on its own stigma.

Do some research on pollination, cross %26amp; self pollination in nature.

There's a Wiki article on it, you can use the sources at the bottom for more info.



Try using the term 'germination' when referring to plant reproduction, you will get a different set of search results than 'feritilization'.
