Abstract

Endogenous hormones that occurred during flower bud morphological differentiation of the bamboo Phyllostachys violascens were determined by indirect enzyme-linked immunosorbent assay （ELISA）. Results showed that with development of flower bud morphological differentiation, the concentration of indoleacetic acid （IAA） and isopentenyladenosine （iPA） initially declined rapidly and then recovered gradually to a relatively stable value. Meanwhile，the concentration of abscisic acid （ABA） and gibberellin （GA） fluctuated but overall showed an updownup curve. The ABA/IAA，GA/IAA，and iPA/IAA values increased then decreased. In addition，the concentrations of iPA and ABA，as well as the ABA/IAA and iPA/IAA values for flowering bamboo were higher than vegetative bamboo with the concentrations of IAA and GA for flowering bamboo being lower than vegetative bamboo. Thus，flower bud morphological differentiation of Ph. violascens could be accelerated or inhibited by appropriate hormones.［Cｈ，６ｆｉｇ．１５ｒｅｆ．］
