摘  要：
植物根际促生细菌(PGPR)对植物的生长发育起到重要作用,是目前生态农业研究的热点之一。为了研究烟草根际生防菌株短短芽孢杆菌(Brevibacillus brevis)DZQ3对烟草促生效果及诱导系统抗性,在温室内进行盆栽试验,以浸根加灌根的方式接种DZQ3。用测定各处理烟株生理指标的方法,包括烟株的农艺性状、生物量,烟草叶片叶绿素含量、电解相对渗透率、超氧化物歧化酶、过氧化物酶、多酚氧化酶、苯丙氨酸解氨酶和过氧化氢酶等系统抗性相关指标及根系发育情况,评价接种DZQ3对烟株的影响。结果表明,DZQ3处理后烟株农艺性状及生物量好于对照,30 d时较为显著(p<0.05);系统抗性相关生理指标优于对照,60 d时最为显著(p<0.05)。生防菌DZQ3对烟草的生长发育具有促进作用,能够诱导系统抗性,增强烟草的抗病能力。

摘  要：
Plant growth-promoting rhizobacteria play an important role in plant growth.In order to investigate the effect of Brevibacillus brevis DZQ3 on tobacco growth and resistance of induction system,pot experiments were conducted in greenhouse and DZQ3 was inoculated into soaking root with filling root.Agronomic traits,biomass and chlorophyll content,leakage rate of electrolyte,systemic resistance related indices,including SOD,POD,PPO,PAL and CAT,and root development situation were measured.The results showed that the agronomic traits and biomass of tobaccos with application of DZQ3 were better than the control(CK),the difference were significant in 30 d.Systemic resistance related indices were better than the control(CK),the difference were significant in 60 d.These results indicate that PGPR strain DZQ3 can promote tobacco growth and induce system resistance,and also enhance disease resistant ability of tobaccos.
