Dave, Guntis was the first one to teach me the fact that all tetraploid 4n are not all 100% 4n. Never assume that everything is 100% 4n or 3n. There never is 100% conversion. Most commercial tetraploids in the marketplace today run about 75 to 85 % 4n, some in the low 60 % range even, with the remainder being 2n and 3n or chromosome missing, etc. Tetraploids never really worked out good for the forcing and cut flower industry because their consistency for flower color and growth rate varies with mass high speed cloning. Also, for the backyard gardener, It's fairly common knowledge that tetraploids, on the overall, have an average life span of 6 to 8 years, after which it's all down hill. There are exceptions, of course. It's worth noting that Guntis Grantis still does his cloning the reliable old fashion way by manual scale cloning.
