根际促生菌筛选及其接种剂对箭薚豌豆生长影响的研究
Assessment of rhizobacteria strains for Viciasativa
摘要
Abstract
To investigate the effect of rhizobacteria inoculants on the growth ofViciasativa,four rhizobacteria strains (J3-1,J1-15,Y16 and J3)were assessed for potentially useful characteristics with the potential to en-hance the growth and yield ofV.sativa;high nitrogenase activity,high phosphate solubilisation and ability to secrete 3-indoleacetic acid (IAA)into the rhizosphere.Strains J3-1,J1-15 and Y16 had the ability to solubilize phosphate and secrete IAA.J1-15,Y16,J3-1 had the strongest phosphate solubilizing capacity (548.9 mg/L), IAA secreting ability (17.8μg/mL),and nitrogenase activity (366.51 C2 H4 nmol/mL·h),respectively.Y16 increased the aboveground biomass and underground biomass ofV.sativaby 104.5%and 254.1%,respective-ly,compared to the non-inoculated control.An inoculant mixture of all four strains increased the aboveground biomass and underground biomass ofV.sativaby 76.1% and 192.3%,respectively,relative to the control. This resulted from an increase in plant height,root length,root surface area,root volume and root activity of 29.4%,70.0%,174.0%,194.6% and 38.3%,respectively.The results suggest that inoculants including mixtures of rhizobacteria strains may have significant benefits forV.sativacultivation.关键词
