摘要
与气候变化有关的主要问题之一是受盐浓度升高和荒漠化影响的土地面积增加。寻找经济、环保的可持续解决方案,有效减轻盐胁迫对植物的损害,具有十分重要的意义。在我们的工作中,对一些天然产品和微生物生物控制剂在减轻莴苣(Lactuca sativa L. var. romana)植物盐胁迫方面的长期有效性进行了评估。通过生物计量(叶片和根的长度和宽度)、生理(叶绿素和脯氨酸含量)和形态学(显微镜下的制备)技术以及 NGS,对施加和不施加盐胁迫的土壤盆中的 14 种不同处理进行了分析,以研究受到不同处理的植物土壤中的微生物群落。在我们的长期实验条件下(90 天),结果表明盐胁迫对植物生长有负面影响。统计分析显示,不同生物刺激剂处理对植物生长的影响存在很大差异。值得注意的是,生物控制剂 Papiliotrema terrestris(菌株 PT22AV)、淀粉芽孢杆菌(菌株 B07)和 Rahnella aquatilis(菌株 36)可作为盐胁迫的缓解剂作用于荠菜。这些发现表明,微生物生物控制剂和某些天然产品都有望减轻盐胁迫对植物的不利影响。
Microbial Biocontrol Agents and Natural Products Act as Salt Stress Mitigators in Lactuca sativa L.
One of the major problems related to climate change is the increase in land area affected by higher salt concentrations and desertification. Finding economically and environmentally friendly sustainable solutions that effectively mitigate salt stress damage to plants is of great importance. In our work, some natural products and microbial biocontrol agents were evaluated for their long-term effectiveness in reducing salt stress in lettuce (Lactuca sativa L. var. romana) plants. Fourteen different treatments applied to soil pots, with and without salt stress, were analyzed using biometric (leaf and root length and width), physiological (chlorophyll and proline content), and morphological (microscopic preparations) techniques and NGS to study the microbial communities in the soil of plants subjected to different treatments. Under our long-term experimental conditions (90 days), the results showed that salt stress negatively affected plant growth. The statistical analysis showed a high variability in the responses of the different biostimulant treatments. Notably, the biocontrol agents Papiliotrema terrestris (strain PT22AV), Bacillus amyloliquefaciens (strain B07), and Rahnella aquatilis (strain 36) can act as salt stress mitigators in L. sativa. These findings suggest that both microbial biocontrol agents and certain natural products hold promise for reducing the adverse effects of salt stress on plants.
