摘    要:在竹鞭侧芽分化过程中,脱落酸仅在秋末冬初已分化的侧芽即将进入冬季休眠前出现痕迹。赤霉酸和玉米素含量均为分化前期高,分化后期低。侧芽无论在早春、夏季还是在秋末冬初分化皆遵循这一规律。不同鞭龄的侧芽分化时,随鞭龄的增大赤霉酸呈上升趋势,玉米素则呈下降趋势。夏季分化的侧芽,上述两种激素含量均高于秋末冬初和早春分化的侧芽。吲哚乙酸含量随分化程度的加深而增加,随鞭龄和分化季节而变化,与赤霉酸含量变化相一致。

关 键 词:雷竹  根状茎    分化  植物激素

Abstract:In the period of mixed bud differentiation,gibberellic acid(GA3)and zeatin(ZT)contents were high at the first stage and low at the laterstage,and higher in summer than in early spring, end autumn and earlywinterIt difered to the law,whatever season was.Abscisic acid(ABA),howeve,was traced only in differentiated bud before winter dormancy.When mixed bud differentiation,GA3 rose and ZT fell with the growing of bamboo rhizome age. Indole acetic acid(IAA)increased with the deepgoingof differentiation,and changed with bamboo rhizome age and season,showingno difference to GA3.
Keywords:Lei bamboo(Phyllostachys proecox    f  preveynalis)  rhizomes  buds  differentiation(biology)  phytohormones
