Default Re: Insights on seed germination.

I think we are not heeding Norm Deno's advice here. He says "The problem all plants have, that most botanists have overlooked, is keeping the seeds from germinating."
So, what happens in the bananas natural habitat? The plant fruits, the fruits get eaten, perhaps pass through the intestinal tract of some animal and get deposited in a pile of dung somewhere. At that point, what will keep the seed from germinating prematurely, i.e. what method would be most useful for the plant to prevent germination unless favorable conditions are present? I would assume these favorable conditions are humidity, the right season, and, most of all, bright light. While humidity has an obvious solution, seasons play less of a role in the habitats of Musa, at least from the temperature point of view. However, most Musa will not stand much of a chance on a dimly lit forest floor and a bright spot, perhaps in a recent landslide, on a cliff or along a stream, would be imperative for successful establishment. So how does a seed that is not light sensitive recognize when it is in a bright enough spot that would make it worth while appearing out of its shell?
Anyone following?

Best, TOBY
