摘　　要：在四川省农科院茶叶所研究了10个茶树品种利用芽下第2叶片形态特征与抗侧多食路线螨(Polyphagotarsonemus latus Banks)的关系.相关分析表明叶片和茎杆夹角与感螨性呈显著正相关,r=0.788,叶片绒毛与感螨性是极显著的负相关,r=-0.798,并有时间动态特征.逐步回归分析结果与相关分析基本一致,茶树抗螨性主要由叶片宽度、叶片角度,叶上绒毛等形态因子确定.因此,茶树抗螨性能由多个叶片形态特征综合决定.Used 10 varieties of tea in thn study,the relationship of morphological characters withvarietal resistance to Polyphagotarsonemus latus Banks were reseached. The results of correlation analysis showed that the angle between leaf and stem appeared a highly significant and positive correlation with the susceptibility to mite of tea ,r = 0.789* *. The length and density of pubesence had a highly negative correlation with the susceptibility. Both these correlations had variance in the different occuring stages. The stepwise regression analysis showed the varietal resistance to Polyphagotarsonemus latus determined by the synthetic effect of more morphological characters of leaf.
