Re: What are some factors that effect or damage seed germination?

I have seen several student projects that have involved microwave effects on 
seed germination but don't know of any research on the subject. Treating seeds 
with microwaves is not used by commercial greenhouses, nurseries, foresters, 
and farmers as far as I know. You named the main environmental factors in seed 
germination. Light can either be required for germination, inhibit germination, 
or have no effect depending on the species. Water and optimal temperature are 
required. Most seeds also require oxygen to sprout. Factors that can prevent 
germination include high salt content, radiation, hard seed coats, immature 
embryos, and chemical inhibitors in the seed.
