14Apr: (day 38) - Rasoli landrace male looks not much like the female at this point. The male is now isolated with two other boys, largely outside and I will transplant this boy later this week, I wasnt sure I was going to keep it but it shows lots of purple and dont want to pass up a chance to inbreed this oddball. The female looks a bit lanky but has fully expressed female. I FIM'ed the boy a few days ago to keep it small and manageable.
7Apr: at the beginning of week 4, we have two Rasoli's. One has decided it's a boy, which seems early as hell, but I have been on 14hrs which is a little close to diurnal triggers, so maybe my fault that it sexed early (not that its a boy). The fact that the other Rasoli shows no sex at this point hints that its a girl, so I can inbreed them. Fingers crossed. Pics later.
Plants, like animals, express sex differentiation as a fuzzy scale where lots of hormones are released. There are inter-relationships between PGR (growth) and auxins, cytokinins and a whole boatload of O-chem stuff that is largely under-studied. So, the Rasoli may have been 58% boy / 42% girl and then environment factors kicked the hormones into overdrive and it expressed itself male. This is not really 'stress' but instead 'adaptation'. Hybrids are IMO less susceptible to this than true landraces, but that's just my guess.
