Abstract

To study the relationship of endogenous polyamines(PAs)with flower bud differentiation of Lycoris chinensis, putrescine(Put), spermine(Spm)and spermidine(Spd) concentrations of the bulbs during different reproductive periods were determined by the thin layer chromatography-fluorescence spectrometry. The results showed that the three kinds of PAs concentrations showed non-synchronous change. The variation of Put and Spm content was sharper; the variation of Spd content was not marked. During the prophase of flower bud differentiation, the Put contentswas more than Spd and Spm, 1.238 nmolg- 1 in the outer squama, 1.676 nmolg- 1 in the middle squama. 2.313 nmolg- 1 in the innersquama and 1.451 nmolg- 1 in the shootapex, in early July. During the flowering period, the Put content decreased, but the Spm content increased. Spm contents was 1.462 nmolg- 1in the outer squama. 1.502 nmolg- 1 in the middle squama, 1.682 nmolg- 1 in the inner squama and 1.536 nmolg- 1 in the shootapex. The ordersof endogenousPAs contents fromhigh to lowwere shoot apex, inner squama, middle squama, outer squama.[Ch, 4 fig. 2 tab. 12 ref.]
