摘要:

为探究接种丛枝菌根真菌(arbuscular mycorrhizal fungi, AMF)对无芒雀麦植株生长特性及糖含量的影响,以‘乌苏1号’无芒雀麦为试验材料,通过盆栽试验法对无芒雀麦接种3种丛枝菌根真菌,即摩西管柄囊霉、根内根孢囊霉和异形根孢囊霉。结果表明,单一接种和复合接种均能有效地侵染无芒雀麦根系,其侵染率为69.83%~80.29%,接种丛枝菌根提高了无芒雀麦生长指标和叶绿素含量,并改善了无芒雀麦根总长、根表面积、根体积、根尖数和交叉数等,其中摩西管柄囊霉和根内根孢囊霉复合接种效果最显著,使总生物量、根总长和根表面积分别较对照提高107.67%、73.34%和79.63%。单一接种和复合接种均显著提高了无芒雀麦叶片和根系的蔗糖及葡萄糖含量,其中复合接种效果更显著。通过隶属函数综合分析得出,摩西管柄囊霉和异形根孢囊霉的复合接种处理对无芒雀麦根系构型的建立和糖含量的改善效果最佳。

Abstract:

In this study, we inoculated Bromus inermis ‘Wusu No.1’ with arbuscular mycorrhizal fungi (AMF) and determined its effects on the growth characteristics and sugar content of the host plant. A pot experiment was conducted using B. inermis ‘Wusu No.1’ and three AMF species-Funneliformis mosseaeRhizophagus intraradices, and Rhizophagus irregularis. These AMF were inoculated alone or in various combinations onto B. inermis plants. The results show that AMF, whether inoculated singly or co-inoculated, effectively colonized the roots of B. inermis, with colonization rates ranging from 69.83% to 80.29%. Compared with non-inoculated plants, those inoculated with AMF showed higher values for growth indicators and chlorophyll content, and higher values for total root length, root surface area, root volume, root tip number, and root cross number. Among the various treatments, the combined inoculation of F. mosseae and R. intraradices had the most significant effect, increasing the total biomass, total root length, and root surface area by 107.67%, 73.34%, and 79.63%, respectively, compared with the control group. Both single and co-inoculation of F. mosseae and R. intraradices resulted in significantly increased sucrose and glucose contents in the leaves and roots of B. inermis plants, with higher values in the co-inoculation treatment. A comprehensive analysis using the membership function method revealed that the co-inoculation treatment with F. mosseae and R. irregularis yielded the best results in terms of establishing root architecture and improving sugar content in B. inermis.
