深色有隔内生真菌对番茄的促生及抗灰霉病效应
Symbiotic Effects of Dark Septate Endophytes on Growth and Resistance to Gray Mold of Tomato Plants
摘要
Abstract
[Objective]Dark septate endophytes(DSEs)were screened for growth promotion and disease resistance to gray mold of tomato plants.[Methods]An experimentation using 8 species of DSEs cultured on PDA plates along with the gray mold,Botrytis cinerea Pers.Fr,was conducted to examine the inhibitory effects of the DSEs on the pathogen.On a MS medium,growth indicators of tomato seedlings germinated from seeds with the DSEs were monitored.Infection rates of the tomato seedlings in the co-culture were observed.[Results]Of the 8 DSEs,Xylaria berteroi(BND 6-R1-13)significantly enhanced the seedling growth,increased the leaf pigments content,boosted the root development(as shown on the increased lateral root number and root/shoot ratio),and heightened the root activity.It significantly inhibited the B.cinerea colony proliferation,achieving a control efficacy of 44.8%.Another DSE,Cordyceps javanica(BND 5-R1-3)significantly increased the lateral root count,root activity,and anthocyanin content of the tomato seedlings.And a third one,Pantospora guazumae first time,the significant inhibitory effects of X.berteroi(BND 6-R1-13)and P.guazumae(BND 5-L2-3)on B.cinerea were reported by this study.In co-culturing with X.berteroi(BND 6-R1-13)for 15 d,the growth of the tomato seedlings was significantly enhanced.In addition,with the significant inhibitory effect on B.cinerea,the DSE would warrant further investigation for tomato farming application.关键词
