Dear All; I have been reluctant to remark on this because I think it is sort of a rhetorical question: you can't. With limited experience, I find that Crinum seed either germinates or dies. Left dry on a garden bench it germinates, put in a cooler it germinates, stuck in a plastic bag, it germinates--- or not. Even if left aside for a long time, the seed will germinate, produce its primary bulb and a leaf or two without benefit of soil or water. Once the energies of the seed have been exhausted the seedling dries up and dies. As far as I can tell you can't really store crinum seed at all. I suppose it depends on how you define 'store'.
