[Method] Culture dish method and pot experi-ment were carried out with the seeds and the seedling of 10 adzuki bean varieties, respectively, and seed germination rate and various indexes of the seedlings were measured. [Result] ① 30 g/L wheat root aqueous extracts very significantly im-proved the germination rate and sprouting index of B1789, Baihong 3, Baohong 947. ② The genotype differences of adzuki bean seedling was presented by the morphological index in wheat root aqueous extracts treatment; among al the mor-phological indexes, Baohong 947, Jinhong 3 presented a positive al elopathic effect, and their plant height, root length and leaf area were extremely significantly in-creased, while the fresh weights of both above-ground and underground parts were increased obviously, compared with the control. ③ According to the synthetical al-lelopathic indices, wheat root aqueous extracts had different degrees of promoting effects on the six adzuki bean varieties： Baohong 947〉Baihong 6〉B1789〉Zunhua-hong〉Jihong〉Jinhong 3〉Baohong 8824-17〉Baihong 3. ④ Treated by wheat root aqueous extract, the SOD activity, POD activity, MDA content, TTC activity and chlorophyl content in the seedlings of adzuki beans of different genotypes changed by a smal er range in al elopathic promotion varieties than in al elopathic inhibition varieties. [Conclusion] The results proved that Baohong 947 is the best summer-planting variety after wheat.展开更多

It is found that under the premise of no influence on root growth of cucumber,extracts from Picrorhiza scrophulariiflora and Punica granatum showed strong prevention and nematicidal activity,and had the similar efficacy of Avermectin; while the extracts from Cibotium barometz,Aucklandia lappa Decne and Fructus cnidii showed low nematicidal activity and various degrees inhibition effect on plant growth.展开更多
