摘    要:激素在果树生长发育过程中起着重要调控作用,基因通过激素控制植株高矮(曾骧,1992).对苹果(Maluspumila)、李(Prunus salicina)、桃(Prunus persica)等果树内源激素与生长势的关系已有一些报道(王丽琴等,2002;周怀军等,2002;孙艳香等,2001),但在核桃上有关研究尚少.本试验以核桃(Juglans regia)不同品种的嫁接植株及实生苗为试材,探讨内源激素与树体生长势的关系,为选择核桃矮化砧木提供理论依据.

关 键 词:核桃  嫁接植株  实生苗  内源激素  生长势

Abstract:The six years walnut(Juglans regia)cultivars (grafting plant) and three years seedlings were used as material to study the change of the endogenous hormone contents in roots and buds and the correlation with growth vigor of walnut in the same year. The results indicated that the endogenous hormone contents in bud of different walnut cultivars had insignificant correlation with the growth vigor. The GA_3 content in roots of walnut seedlings had positive significant correlation with tree height and its increment. The ABA content in roots of walnut seedlings had strikingly negative relationship with tree height and its increment, and trunk girth. The GA_3 content in buds of walnut seedlings had positive correlation significantly with the increment of tree height and the ABA content in buds of walnut seedling had strikingly negative relationship with tree height and its increment. The IAA content in roots of walnut seedlings had bally positive correlation significantly with that in buds.
Keywords:Juglans regia  grafting plant  seedling  endogenous hormone  growth vigor
