Those aren't "tricks" but different types of stratification. I'm aware that different seeds require different types of stratification: scarification (nicking, scratching the outer covering), soaking or using acid to emulate natural wearing/decomposition or in the case of certain seeds even being exposed to fire/extreme heat. In all these cases the reason is usually fairly obvious; in order to allow moisture, etc. to penetrate the outer coating. My question pertains specifically and exclusively to "Cold stratification". By "tricking seeds" I'm wondering if the seed can be "fooled into thinking" it's been dormant a season or two though, in actuality, they've only been in the freezer/refrigerator for a week or so. If it is merely a matter of expansion, contraction, cold-induced cracking --- a transition from one state to the other and back--- one day'd be as good as 90. I always do (usually fairly extensive) research before posting on any forum. On this subject, I mostly found answers to the "what is?s" and "how?s" but not so much the "why?s". Here I thought I might find others with anecdotal experience from experimentation. Just as one example, right now I have a large patch of Cilantro/Coriander (Coriandrum sativum) that, though I grew it in order to use the (Cilantro) leaves, has already gone to seed. There's still plenty of growing time left this season. It'd be nice if I could harvest this year's seed, do a "Quickie Cold stratification", plant and get a second crop this year. This is an experiment I plan to be trying . |
