The results show that Stellaria media (L.) Cyr., Stenoloma chusana (L.) Ching, Sedum sarmentosum Bunge and Humulus scandens (Lour.) Merr. have inhibitory effects. Bidens bipinnata L. and Pueraria lobata (Willd.) Ohwi have no obvious inhibitory or stimulative effects.展开更多

The results showed that its nutrient components are accorded with the standard of modern food. The dry resistance was strong, the 80%-90% of leaves were wilting at soil water content about 6.2%. The cold resistance was poor, electrolyte leakage rate of leaves was 47.88% at 0℃ and LT50 was merely -0.9℃, So this plant grow unhealthy in field on winter in Nanjing.展开更多
