I have my own theory regarding that reasoning: I believe a female plant that switches sex in response to stress, is a 'weaker' plant, and not a trait I would want to continue ... I have purposely tried to force a sex reversal on quite a few plants, and I select the ones that tolerate the stress, without reversing sex ... if I was breeding dogs, i wouldn't pick the smallest, weakest pup of the litter, I would choose the strongest and healthiest ... granted, I'm not a scientist, and this is only my opinion, so take it for what its worth ... :jointsmile:
