Antifeedant and oviposition deterrent effect of extracts from xanthium sibiricum and other medicinal plants against plutella xylostella l . lepidoptera : plutellidae 苍耳等药用植物提取物对小菜蛾的拒食作用和产卵忌避效果
The sequence of lead content in each hyperaccumulator was bidens maximowiciziana > amaranthus tricolor > sophora japonica > xanthium sibiricum > schizonepeta fenuifolio > vetiveria zizanioides in this study . on one hand , bidens maximowiciziana and amaranthus tricolor could transport the iiiost of the lead from roots to the above - ground parts , and the total heavy metal translocated ( tmt ) of bidens maximowiciziana and amaranthus tricolor rose to the 11 . 29mg and 9 . 17mg in 100 plants 结果表明，羽叶鬼针草和绿叶苋菜能把吸收的pb较多地运输到地上部， 100棵羽叶鬼针草和绿叶苋菜地上部的迁移总量高达11 . 29mg和9 . 179mg ；羽叶鬼针草根系对pb的耐性最强，当pb处理浓度为loomg
The results showed that the extracts from the whole of solanum nigrum had 100 % inhibiting rates to rhizoctonia solani and cladosporium ucumerinum fruits of solanum nigrum also had 100 % inhibiting rates to fusarium oxysporium , extracts from fruit of xanthium sibiricum had 100 % inhibiting rates to rhizoctonia solani ; extracts from the whole of artemisia annua had more than 78 . 5 % inhibiting rates to fusarium oxysporium , alternaria solani and rhizoctonia solani 结果表明：龙葵全株粗提物对辣椒丝核和黄瓜黑星病菌、龙葵果实提取物对黄瓜枯萎病菌、苍耳果实提取物对辣椒丝核病菌的抑制率均为100 % ；黄花蒿(全株)提取物对黄瓜枯萎病菌、番茄早疫病菌和辣椒丝核病菌的菌丝抑制率都分别达到了78 . 5 %以上。
