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 GA3 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 GA3 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.

Key words: Juglans regia, grafting plant, seedling, endogenous hormone, growth vigor
