Abstract The aim of this study was the mycorrhizae inoculation effect on production and mineral nutrition of snap bean variety under low phosphorus intake. The experiment was a randomized block design with four treatments: a non-mycorrhizal control, two mycorrhizal strains: Piriformospora indica (Piri), Glomus intraradice (Glomus), and their combined inoculation Piri + Glomus; using ten replicates per treatment. A comparative trial of different treatments on plant growth, yield parameters, mineral absorption and mycorrhizae colonization frequency was conducted in the greenhouse under controlled conditions using autoclaved soil-sand-vermiculite substrate. The inoculation with Piri and co-inoculation with Piri + Glomus significantly increased aerial dry biomass (p ≤ 0.01) and highly increased root dry biomass (p ≤ 0.001). Mycorrhizal snap bean plants showed a significantly higher number of pods, pods dry weight, dry weight of seeds per plant, and percentage of mycorrhizal colonization than non-mycorrhizal plants. Mycorrhizae inoculation increased significantly nitrogen and phosphorus uptake that the inoculation with Piri increased N uptake in roots by 187% and P uptake by 200% compared to the non-inoculated plants. For cations leave incorporation, Piri significantly enhanced Ca2+ by 100%, Mg2+ by 110% and NH4+ by 175% relative to the non-mycorrhizal plants. While mycorrhizal inoculation doesn’t have a significant effect on K+ nutrition. In conclusion, snap bean Contender variety seedling inoculated with Piri proved to be most effective by improving plant growth, mineral nutrition and yield production under low phosphorus uptake.

低磷条件下籼稻梨状孢对菜豆生长和矿质营养的潜在影响

摘要 本研究的目的是研究菌根接种对低磷摄入条件下脆豆品种产量和矿质营养的影响。实验是一个随机区组设计，有四个处理：一个非菌根对照，两个菌根菌株：梨形孢菌（Piri）、Glomus intraradice（Glomus），以及它们的组合接种 Piri + Glomus；每个处理使用十个重复。使用高压灭菌的土壤-沙-蛭石基质在受控条件下在温室中进行了不同处理对植物生长、产量参数、矿物质吸收和菌根定植频率的比较试验。接种 Piri 和共接种 Piri + Glomus 显着增加了地上干生物量 (p ≤ 0.01) 和高度增加的根干生物量 (p ≤ 0.001)。与非菌根植物相比，菌根脆豆植物的豆荚数、豆荚干重、每株种子干重和菌根定植百分比显着更高。接种菌根显着增加了氮和磷的吸收，与未接种的植物相比，接种 Piri 使根部的 N 吸收增加了 187%，P 吸收增加了 200%。对于阳离子离开掺入，相对于非菌根植物，Piri 显着增强了 Ca2+ 100%、Mg2+ 110% 和 NH4+ 175%。而菌根接种对K+营养没有显着影响。总之，事实证明，在低磷吸收条件下，通过改善植物生长、矿物质营养和产量生产，接种 Piri 的脆豆 Contender 品种幼苗最有效。
