三七总皂苷及两种单体皂苷对三七幼苗的化感作用研究
Allelopathic effects of Panax notoginseng saponins and two saponins on Panax notoginseng seedlings
摘要
Abstract
The effects of Panax notoginseng saponins(PNS),ginsenosides Rg1and notoginsenoside R1at different concentrations on the growth and physiology of P. notoginseng seedlings were studied in this pa-per. The results showed that shoot height,main root length,soluble protein content,soluble sugar con-tent and CAT activity in treated P. notoginseng seedlings were decreased. The shoot height and main root length of seedlings treated with PNS and ginsenosides Rg1 were decreased obviously; the soluble protein content in the seedlings treated with 0.01,0.10,1.00 mg·L-1ofPNS were dramatically lower than those of 28.83%,17.07% and 23.21% in control groups. The POD and SOD activity of seedlings were also reduced by PNS. However,SOD activity of seedlings treated with ginsenosides Rg1and notog-insenoside R1were increased. It indicated that these three saponins had allelopathic inhibitory effects on P. notoginseng seedlings.The effects of PNS were most significant among thesethree saponins.关键词
