Je suis pas très doué pour traduire l'anglais, mais c'est assez facile à comprendre:
«Backward" hermaphrodites are declared males that eventually sport female flowers (as opposed to the usual female-to-male hermaphrodites). Thes"Backward" hermaphrodites are declared males that eventually sport female flowers (as opposed to the usual female-to-male hermaphrodites). These are rare occurences, usually sterile but sometimes viable, that I found to be genetically valuable. Many resinous and desirable males exhibit this trait, which almost guarantees against unwanted hermaphroditism in subsequent generations as it also increases the female-to-male ratio in its progency."
In his book (pamphlet) "Cultivating exceptional cannabis" DJ Short says that he has found "reverse herm" males can be an indicator of potency sometimes, he goes on to say that the presence of female pistils on the male will inevitably result in higher females (because there is more chance for selfed seeds)...»
Toujours sur le même sujet, Raco, un cultivateur espagnol , commente que Nevil a déjà réverti un mâle Haze, il y a une vingtaine d' années, et qu' il l'avait ensuite croisé avec un autre mâle Haze pour produire une lignée qu' il avait ensuite utilisée dans ses projets de breeding.
Il y a également ce post de Sam Skunkman sur ICMag concernant la réversion de mâles:
«Fertile female flowers can be induced in male plants by ethephon (2-chloroethanephosphonic acid) and NIA 10637 (ethylhydrogen-l-propylphosphonate). Interestingly, stamens could be seen arising even from fruits. Stopping the application of growth regulators caused the plants to revert to their original sex. We hypothesized that in Cannabis, GA and ethylene act as male and female hormones respectively, and that the expression of sex is controlled by a balance between their endogenous levels. Abscisic acid (ABA) is able to overcome the GA induced male flower formation (Mohan Ram and Jaiswal 1973; Mohan Ram and Sett 1985).

Although many environmental groups worry about toxicity resulting from use of growth hormones and fertilizers, the toxicity of ethephon is actually very low, and any ethephon used on the plant material is converted very quickly to ethylene.»"

**Mohan Ram est un botaniste considéré comme étant le père de la réversion sexuelle du cannabis. On lui a même dédié une variété:

pour le reste je le découvre, et le fait que la présence de pistils femelles sur le mâle va inévitablement entraîner un plus grand pourcentage d'individus stables dans la descendance, je dirais que ça me rassure dans mon choix 
)
elle est donc à 45 jours de floraison, apex coupé pour qu'elle prenne plus de volume que de hauteur. cela dit elle aurait été pas mal en scrog 
je vais certainement lui faire une régénérescence en fin de flo pour essayer de la récupérer.
