Due to its increasing economical values, sunchoke is widely planted including in Northeast Thailand where insufficient water supply recurs. This work then aimed to investigate the efficiency of 5 different AMF species to enhance growth of sunchoke under drought stress conditions. Factorial experiments in a randomized complete block design (RCBD) were conducted with four replications under two conditions, a well-watered (WW) and a drought stress (DS). This result showed that Rhizophagus irregularis BM-2 g1, Glomus hoi KKU g3 and Rhizophagus aggregatus BM-3 g3, were the best AMF to enhance the growth and yield of sunchoke. We found that Glomus etunicatum UDCN52867 g5 less affected the growth of sunchoke when compared to the other Glomus spp. in this work. Different AMF species belonging to Glomales affected different plant growth parameters at different levels. This suggested a variety of plant growth promoting functions of Glomus spp. Moreover, Acaulospora mallea KKU-NBP-SB-2, isolated from Eucalyptus plants, did not significantly enhance the growth and yield of sunchoke under both WW and DS conditions. This suggested that plant-AMF symbiosis is a species-specific interaction. Detailed mechanisms of AMF and an application of a combination of AMF species with different functions to enhance sunchoke growth are worth investigating.

由于其经济价值的提高，防晒霜被广泛种植，包括在泰国东北部，那里的供水量不足。然后，这项工作旨在研究5种不同AMF物种在干旱胁迫条件下增强抗日光草生长的效率。随机完全区组设计（RCBD）中的析因实验在两个条件下进行了四个重复，分别是浇水充足（WW）和干旱胁迫（DS）。该结果表明，不规则根瘤菌BM-2 g1，Glomus hoi KKU g3和集合根瘤菌BM - 3 g3是增强抗ch生长和产量的最佳AMF。我们发现，Glomus etunicatum与其他Glomus spp相比，UDCN52867 g5对防晒油的生长影响较小。在这项工作中。属于Glomales的不同AMF物种在不同水平上影响了不同的植物生长参数。这表明Glomus spp具有多种促进植物生长的功能。此外，分离自桉树植物的马齿AcKKU -NBP-SB-2，在WW和DS条件下均未显着提高抗阳萎的生长和产量。这表明植物-AMF共生是物种特异性的相互作用。AMF的详细机理以及将具有不同功能的AMF种类组合以增强抗日光浴剂生长的应用值得研究。
