摘　　要：以江西君子谷刺葡萄、怀化白葡萄和浙江白刺葡萄作为接穗,以红地球、户太8号、黑峰、瑰宝和贝达作为砧木,对各嫁接组合的亲和性、相关形态指标和生理指标进行测定和比较,并对叶片和果实的抗病性作了观察。结果表明：浙江白刺葡萄/贝达组合亲和性要优于其他嫁接组合;在花后45-60 d,叶绿素总量达都到最大值,之后呈下降趋势;叶绿素的a/b值都呈先下降后升高的趋势;类胡萝卜素随着叶片的生长和发育,含量呈下降的趋势,在花后60 d左右达到最低值,随后升高,后又呈下降的趋势;霜霉病和黑痘病的发病率和病情指数在整个发病周期内呈持续下降的趋势,以贝达、户太8号为砧木的嫁接组合,霜霉病和黑痘病的发病率和病情指数均较低。Using V. davidii Fo?x including Jiangxi Junzi Vally, Huaihua Bai and Zhejiang Bai as scion, V. Viniferaincluding Red Globe, Heifeng, Guibao and Beta as rootstock, to determine and compare with each grafting combination's affinity, related morphological indexes and physiological indexes, and observeing in resistance of leaves and fruits. The results indicated that V. davidii Fo?x Zhejiang Bai/Beta was better than other grafting combination; about 40~65 days after flowering, total chlorophyll content up to the maximum value, after that rendering a downward trend; Chlorophyll a/b value rendered the tendency of first declined and then increased; with the growth and development of the leaves, carotenoids' content rendered downward trend, reaching the lowest value at about 60 d after flowering, then it raised, again it rendered downward trend; the incidence and disease index of downy mildew and anthrachose of grape were continued to decline throughout the entire disease cycle trends, using Beta and Hutai 8 as rookstock, the incidence and disease index of two kinds of disease were lower.
