Abstract

The contents of endogenous polyamines (putrescine , spermidine and spermine) on flower buds of Ginkgo biloba were analyzed during the differentiation .The results showed that the concentration of putrescine and spermidine increased markedly and had a peak at the physiological differentiation stage of female and male flower buds and spermine concentration showed a slight increase .The three kinds of polyamines were very low when the morphological differentiation began .At morphological diffdfentiation stage , putrescine and spermidine concentrations on female flower buds increased again .The changes of putrescine concentration on maleflower buds was similar to that on female flower buds .Spermidine content of male flower buds showed a peak before early July and then kept at a low level at the mirosporocytes differetiation stage .Spermine concentrations on female and male flower buds was low and showed no significant change during the stage .The date indicate that there is some intermal connection beween polyamines and flower buds differentiation .
