Abstract:
Taking Camptotheca acuminata seedlings as material,the effect of different inoculation time on the photosynthesis of Camptotheca acuminata seedlings with arbuscular mycorrhizal fungi (AMF) in the greenhouse were studied.The results showed that AM formation was contributed to enhancement of the photosynthetic pigment content，net photosynthetic rate (Pn)，stomatal conductance (Gs) and transpiration rate (Tr) in leaves of C.acuminata seedlings.But the promoting effect of AMF was got by different inoculation time，and weakened with the delay of inoculation time.The photosynthesis of seedlings inoculated with Acaulospora mellea?at 0 day and 20 days after grow true leaf was obviously promoted.The chlorophyll a content，chlorophyll b content，total chlorophyll content，Pn，Gs and Tr of seedlings inoculated with A.mellea at 0 day after grow true leaf were the highest，and which was remarkable higher than non-mycorrhizal seedlings.Also the effective quantum yield (EQY) and photochemical quenching (qP) was significantly higher than non-mycorrhizal seedlings.The chlorophyll a/b，carotenoid content and maximal photochemical efficiency of PSII in the dark (Fv/Fm) of seedlings inoculated with A.mellea at 20 days after grow true leaf were the highest.The photosynthetic pigment content，Pn and Fv/Fm of seedlings inoculated with A.mellea over 20 days after grow true leaf，which including the 40 days，60 days and 80 days were higher than or closed to non-mycorrhizal seedlings.And the promoting effect was very limited.
