Abstract:
Soybean root exudates extracted with XAD -4 resin were identified by GC -MS method , and the allelopathyof chemical compounds (1 , 2 -benzenedicarboxylic acid)on soybean seedling were inresti-gated in this study .The resultsshowed that root exudates extracted with XAD -4 resin was identified as long -chain fatty acids , benzoic acids andits derivates , straight -chain alcohol , enol , phenol , ketone , ester and some hydrocarbon , most of which were also allelopathiccompounds reported .In certain range of concentrations , the 1 , 2 -benzenedicarboxylic acid significantly inhibitedthe growth of soybean seedlings .The results showed that soybean root exudates contained allelopathic compounds thatinhibited seed germination and seedlings growth , and this might cause soybean continuous cropping barriers .
