Re: seed culture

From: grsjr at juno.com (George R Stilwell, Jr.) on 1997.12.05 at 13:29:50(1710) Lynn, Nearly all Arisaema seed do not require a cold period to germinate. A. triphyllum should +More germinate easily. I use the Deno method for seed germination, so the media is a scrap of wet paper towel. Once the radical emerges, carefully transfer the seedlings to any sterile mixture and keep them moist. You will probably have some problem growing the plants to best advantage because they do like a cool period when they go dormant. It doesn't have to be really cold although we really don't know exactly how cold it has to be. My guess is in the 50F range or lower. In the north, we lifted tubers like Glads, etc. and stored them nearly dry for the winter. The same will work in the South for Arisaema storing them in the refrigerator. But, what we really need is a good study with a range of storage temperatures and times including control subjects,etc. Ray
