摘要

为探究接种印度梨形孢对核桃幼苗耐盐性的影响,以核桃幼苗为材料,通过盆栽试验,设置接种印度梨形孢(接种和未接种)与盐胁迫两个因素(盐浓度梯度为0、25、50、75、100mmol/L),监测接种不同时间后核桃幼苗的生长指标。结果表明:随接种时间延长,接种印度梨形孢后的核桃幼苗生长量较对照显著增高,其菌根促生效应日渐显著;随盐浓度升高,接种后的促生效应呈下降趋势;接种后不同盐浓度下核桃幼苗的各生物量均高于未接种。TOPSIS法综合分析结果表明,不同盐浓度下接种的生长效应均高于对照组。因此,印度梨形孢与核桃幼苗共生可以促进核桃幼苗生长,有效提高核桃幼苗的抗盐性。
        In order to explore the effect of inoculation of Piriformospora indica on the salt tolerance of walnut seedlings, two factors(inoculation and non-inoculation) and salt stress(in salt concentration gradients of 0, 25, 50, 75, 100 mmol/L) were set by pot experiment to monitor the growth indicators of walnut seedlings after different time of inoculation. The results showed that with the prolongation of inoculation time, the growth of walnut seedlings after colonization of Piriformospora indica was significantly higher than that of the control, and the mycorrhizal growth effect was more and more obvious. With the increase of salt concentration, the growth-promoting effect after inoculation showed a downward trend. The biomass of walnut seedlings under different salt concentrations after inoculation was higher than that of non-inoculation. The results of comprehensive analysis by TOPSIS showed that the growth effects of inoculation under different salt concentrations were higher than those in the control group. Therefore, the symbiosis of Piriformospora indica and walnut seedlings could promote the growth of walnut seedlings and effectively improve the salt tolerance of walnut seedlings.
