摘要
以薰衣草为试材,采用丛枝菌根真菌(AMF)单接种(根内球囊霉Gi、摩西管柄囊霉Fm、幼套球囊霉Ge)和混合接种的方法,研究了高温胁迫和高温+水淹胁迫试验条件下,薰衣草菌根化对长江中游高温高湿的响应情况,以期为解决薰衣草在我国中部及南方地区应用的障碍提供参考依据。结果表明:1)混合接种AMF处理的侵染率最高(37.50%);接种Fm的薰衣草生物量(株高、鲜质量、干质量)均高于对照;2)在高温及高温水淹胁迫时,薰衣草接种处理的可溶性蛋白质、可溶性糖及脯氨酸含量均高于对照,丙二醛和过氧化氢含量均低于对照;Mi、Fm、Ge处理的内源ABA含量升高可能是忍耐高温胁迫的主要因素之一。菌剂Mi、Fm 2个处理对薰衣草耐受高温及高湿环境表现出正向的效果。薰衣草菌根化在一定程度上增强了其适应高温的韧性能力。
Taking Lavandula angustifolia as the test material,single inoculation(Glomus intraradices(Gi),Funneliformis mosseae(Fm),and Glomus etunicatum(Ge))and mixed inoculation of arbuscular mycorrhizal fungi(AMF)were used to study the response of L.angustifolia mycorrhizal fungi to high temperature and high humidity in the middle reaches of the Yangtze River under high temperature stress and high temperature+water flooding stress conditions,in order to provide reference for solving the obstacles to the application of lavender in central and southern China.The results showed that,1)the mixed inoculation AMF group had the highest infection rate(37.50%);the lavender biomass(plant height,fresh weight,dry weight)inoculated with Fm was higher than the control;2)under the high temperature and high temperature waterlogging stress,the content of soluble protein,soluble sugar,and proline in the Lavandula angustifolia inoculation treatment was higher than that in the control,while the content of malondialdehyde and hydrogen peroxide was lower than that in the control.In addition,the enhanced hormone contents of Mi,Fm and Ge were the main possible reason for enduring the high temperature stress.The two treatments of Mi,Fm showed the positive effect to endure high temperature,high humid environment.Lavandula angustifolia mycorrhizal enhanced its toughness to adapt to high temperature to a certain extent.
