Re: Re: HYB: pod ripening/germination

I think Linda Mann was doing an experiment with an unshelled pod.  If I remember correctly she had reported that the pod was decomposing, so I expect the risk to newly formed roots would be minimal.  

However, it may be that this was a green pod to begin with.

   It is best then to shell the seeds prior to placing them in the fridge
then? I wouldn't want to miss any that germinate, or break off any fragile new
shoots or roots trying to shell them after germination.
Thanks.
