印度梨形孢对濒危藏药薄叶鸡蛋参生长和生理特性的影响
Effect of Piriformospora indica on Growth and Physiological Characteristics of Endangered Tibetan Medicine Codonopsis convolvulacea Kurz.var.vinciflora(Kom.)L.T.Shen
摘要
Abstract
In order to improve the yield and stress resistance of cultivated Codonopsis convolvulacea Kurz.var.vinciflora(Kom.)L.T.Shen,the promotion effects of endophytic fungus Piriformospora indica on its growth were explored.The effects of P.indica on the growth and physiological characteristics of C.convolvulacea were studied by outdoor pot experiment with two treatments of control group(CK)and inoculation group(PI).The results showed that the symbiotic system of P.indica and C.convolvulacea was successfully established by soaking and watering inoculation,and the colonization rate was 70.37％.Compared with CK,the leaf number,stem number,main stem length,aboveground fresh weight and dry weight of C.convolvulacea colonized by P.indica were significantly increased by 101.27％,102.41％,76.07％,278.23％and 265.52％,respectively.The fibrous root number,fibrous root length,underground fresh weight and dry weight were significantly increased by 52.57％,63.39％,23.65％and 32.52％,respectively,and the tuber diameter was increased by 12.14％.The activities of catalase(CAT)and peroxidase(POD)were significantly increased by 9.79％and 19.35％,respectively,and the activity of superoxide dismutase(SOD)was reduced by 28.02％compared to CK.The contents of soluble sugar and proline were significantly increased by 42.84％and 92.19％,respectively.Root activity was significantly increased by 65.57％.In summary,P.indica can promote the growth and enhance stress resistance of C.convolvulacea,and can be used to improve the cultivation quality of C.convolvulacea.关键词
