%X The effects of cont inuous cropping on the growth of eggplan t and its mechanism were studied with po t experiments.The results show that duri ng the growth period of 45 days,under th e condition of continuous cropping,the p lant height,leaf area,main and total roo t lengths of the eggplants are obviously ,lower than those under the condition of mono-cropping,causing the shoot and roo t fresh weights of eggplants to decrease by 33.2% and 30.2%,respectively and the endangerment of Meloidogyne becomes more severe with the growth of eggplant seedings.Although Meloido gyne are eliminated by autoclaving continuous mono-cropping soil,eggplant seedlings growth can not be improved com pared to mono-cropping ones growing in s terilizing soil,and the germination of eggplant seeds under continuous mono-cro pping is lower by 15% than that under mo no-cropping in 7 days after planting,whi ch suggests that the obstacles of contin uous cropping maybe result from Me loidogyn and allelopathy.It is fur ther verified that the more the adding r oot exudates is,the more their inhibitio n on the growth of eggplant radicles and plumules is,indicating that allelopathy is one of the important genes in the ob stacles of eggplant continuous cropping.
