Chailakhyan(1936年)最早提出的成花素假说,表明植物含有一种开花素.这个理论得到几个有关成花素可通过嫁接传递的成功试验所证实.大多数草本植物、一年生植物,它们都要经过光周期和春化处理的刺激后才能开花.然而,成花素假说未能在木本树种上得到验证,这可能是因为木本树种在开花方面对光周期一般不敏感以及在温室难以控制的原因.在芒果等几种果树中,花期的交替是一个很大的问题.但“淡季”芒果品种与其它
The garglinghypothesis first proposed by Chailakhyan (1936) shows that plants contain a fl ow, a theory that has been corroborated by several successful experiments on the transfer of florin through grafting.1 Most herbs, annuals, However, the floriucine hypothesis failed to be validated on woody species, probably because woody tree species are generally insensitive to photoperiod on flowering and difficult to heat in the greenhouse The reason for the control is that the alternation of flowering is a big problem in several fruit trees, such as mango, but the “off-season” mango variety and others
