弱光下PGPR对重瓣百合开花期光合特性及生长的影响
Effects of Plant Growth Promoting Rhizobacteria on Photosynthetic Characteristics and Growth of ′Carolina′Before and After Florescence Under Low Light
摘要
Abstract
Taking Holland double Lily ′Carolina′ as material, the photosynthetic indexes and plant growth were researched by inoculating potted with Sphingobacterium ( SN-2) , Acinetobacterium ( BG and XG) , Chryseobacte-rium ( F) and 4 mixed PGPR strains under low light conditions. The results showed that with 70% shading condi-tion, there were some differences on promoting photosynthetic characteristics and growth of′Carolina′which inocu-lated different strains before and after flowering, the maximum net photosynthetic rate (Pmax), light saturation point ( LSP ) and apparent quantum yield (?) of plants were significantly increased by inoculatingwith XG, SN-2 and HH compared with the control, while the effect of mixed inoculation of HH on′Carolina′was better than that of sin-gle inoculation with XG and SN-2, which indicated that there may be an interactive effect among different strains, but the growth effect was not obvious by inoculating F and BG strains, which may be related to light intensity. In addition, the SPAD content and plant height of ′Carolina′ were significantly increased by inoculating with XG,SN-2 and HH, especially the effect of HH on plant height was obvious. HH and SN-2 promoted the flowering time of ′Carolina′to be 3 to 7 days earlier than the control, and XG followed.关键词
