Bill, if you can get a copy of the Society for Louisiana Irises Special
Publication - 1995, it has two very interesting articles describing
experiments for germinating LA's by Sam Norris and Joe Mertzweiller. Sam's
experiment involved taking the corky outer coat off of ALL 156 seeds he was
experimenting with. His experiment, as I understand it, was attempting to
determine the best moisture level for stratification and experimenting with
both warm and cold stratification. It appears Joe was attempting to speed up
germination, which he did in his experiment with 1200 seeds. He divided them
into 5 groups and applied various techniques. He reported germination in
10-15 days after planting seeds that he had peeled, hydrated, stratified and
cut. as opposed to 70-80 days for seeds planted with the corky cover in place.
Both are very interesting pieces of work. If you can't find the articles,
perhaps I could copy them and send them along.
