Can a plant make bad pollen if stressed?

[Frozenguy]

Hey guys and gals. I was wondering if anyone knew if the pollen from a stressed male would be lower in quality or just yield. I have a plant that started flowering outdoors and it's a male and I wanted to do some breeding. He looks stressed because the sprinklers overwatered him a few times..

But he will make the same pollen right? Not stressed or mutated pollen?

Shouldn't realy affect it, my critical mass male was stressed and he was fine still got some of his pollen in my freezer...

A very good question , was thinking similar recently when considering to use pollen from a sad damaged mite nibbled plant or wait weeks for a healthy one to drop.
Collected pollen but never used it as could not find a definative answer.

If stressed males produced a higher incidence of non lethal mutations it could explain some of the freaks that show up from a stable line.

wow good question never thought about it. I wouldn't think so though...

Saying that stress affects genetic potential is the same as saying environmentally aquired traits are inherited. Lamarck thought that, but Darwin disagreed.

All our males get stressed, have never had any issues. This would be much the same as saying a human male under stress is more likely to have problematic sperm..... mine seems to be fine lol.

I think that stress will effect Meiosis and Mitosis. Stressors during Meiosis could very well effect the frequencies of distribution for certain genes during recombination.

I do not believe it is a random process as I do not believe there is such a thing as a random process in general but rather chaotic. Chaos is non-random.

Meiosis is a more complicated form of Mitosis. Why wouldnt stress effect Meiosis if stress does effect Mitosis?

I have stressed males before with no problems.

Maybe this question is not settled yet.

I tend to under water mine sometimes and have never had any problems.
