%X Autotoxic effects of aqueous extracts from eggplant residues were studied. The results show that the aqueous extracts inhibit obviously its radicle growth at the concentration of 0.015g/mL. Although the embryo growth is simulated at low levels,the inhibitory effect is observed as the concentration reaches 0.075g/mL, indicating that the aqueous extracts have strong autotoxic effects on eggplant. Moreover, methanol isolatable components in aqueous extracts inhibit the growth of embryo, radicle and seedling, indicating that the methanol?dissolved components contain some autotoxic substances.The root vigor of eggplant seedling declines as the concentration of the methanol isolatable components increase. Autotoxic substances in the methanol isolatable fraction depress the uptake of NO - 3, PO 3- 4, K , Mg 2 and Ca 2 , indicating that the inhibition on ion uptake is an important aspect of autotoxic effects.
