Abstract
Mycorrhizal dependence(MD)of five vegetables in Cucurbitaceae to two Arbuscular mycorrhizal fungi Glomus mosseae (G.m) and Gigaspora rosea (Gi.r) was investigated under green house conditions.Results showed that the growth,leaf area,photosynthetic rate and dry mass were significantly enhanced and the stomatal resistance was reduced by the fungi,with the order of MD of the vegetables being cucumber>watermelon>balsam pear>bottle gourd>squash.There was a positive correlation between MD and infecting rate. Its linear regression equation is:y =117.19+0.7468x.
