Abstract

The current study aimed to compare between inoculation of wheat plant with a single and combinations of several species of Arbuscular mycorrhizal fungi (AMF), and promoting its growth under water stress conditions. In a greenhouse experiment, the effect of three AMF species on wheat plant growth was studied using single-inoculations with Glomus monosporum, G. mosseae and Gigaspora gigantean, and mixtures of various AMF species. Moreover, inoculation of wheat plant with pair of AM fungi composed mainly of; SN (G. monosporum and Gigaspora gigantean) and AA (G, monosporum and Glomus mosseae) were investigated. Current findings indicate that inoculation with AMF belonging to different families was more effective in improving plant growth than AMF from the same genus and with mono-inoculation. Results showed that plant height inoculated with SN and AA increased by 27.30% and 24.95; respectively, while inoculation with Gigaspora gigantean (GG), G. mosseae (GS) and G. monosporum (GM) increased by 16.01%, 14.6% and 6.83%, respectively. Number of spikes/plant, spike length, number of spikelet/spike, 1000-grain weight and grain yield/plant of wheat plants inoculated with AMF increased significantly, compared with the non-inoculated control plants under water stress. In addition, current results demonstrated that inoculation with SN had relatively higher impact on promoting the growth of wheat plants followed by AA and GG, suggesting that inoculation with AMF consisting of different species may have a better effect than single inoculations. Furthermore, it is observed also that SN; which are combination from different genera have better effect on wheat plant growth, compared to that of AA from the same genus but of different species.
用丛枝菌根真菌的单一和组合接种剂接种干旱胁迫的小麦(Triticum aestivum L.)
本研究旨在比较用单一和几种丛枝菌根真菌(AMF)组合接种小麦植株,以及在水分胁迫条件下促进其生长。在温室试验中,用单孢Glomus monosporum、G.mosseae和Gigaspora gigantean以及各种AMF物种的混合物单次接种,研究了三种AMF对小麦植株生长的影响。此外,小麦植株接种的AM真菌对主要由以下组成:;对SN(G.monosporum和Gigaspora gigantean)和AA(G,monosporm和Glomus mosseae)进行了研究。目前的研究结果表明,用不同科的AMF接种比用同一属的AMF和单接种更有效地改善植物生长。结果表明,接种SN和AA的株高分别提高了27.30%和24.95;接种大孢菌(GG)、苔藓菌(GS)和单孢菌(GM)分别提高了16.01%、14.6%和6.83%。在水分胁迫下,接种AMF的小麦植株的穗数、穗长、小穗数、1000粒重和单株产量均显著高于未接种对照。此外,目前的结果表明,SN接种对小麦植株生长的促进作用相对较高,其次是AA和GG,这表明由不同物种组成的AMF接种可能比单次接种效果更好。此外,还观察到SN;与同属不同种AA相比,不同属组合AA对小麦植株生长有更好的影响。
