Abstract:
Taking Lolium perenne as experimental material，the effects of Trichoderma harzianum colonization on the growth and development，the degree of root impregnation symbiosis，chlorophyll fluorescence parameters，gas exchange characteristics，chlorophyll content and biomass accumulation of L.perenne were studied by using the methods of inoculation and non-inoculation，in order to provide reference for the application of T.harzianum in the production of L.perenne.The results showed that，1) T.harzianum inoculation significantly improved the stomatal conductance (Cond) and transpiration rate (Tr) of L.perenne，and significantly increased the water deficit (VpdL).2) T.harzianum inoculation the quantum yield (Y (NPQ)) of regulatory energy dissipation of L.perenne in PSⅡ.3) T.harzicum inoculation significantly increased the net photosynthetic rate (Pn)，biomass accumulation，and tiller numbers of L.perenne.In conclusion，T.harzianum could be used to promote the growth and development of ryegrass.
