A pot inoculation experiment was conducted under three abiotic stress conditions-drought, cold, and saline-alkali stress—to analyze the effects of rhizosphere inoculation on the growth indices, physiological characteristics, and root morphology of perennial ryegrass. The results showed that inoculation with B. paralicheniformis significantly alleviated the growth inhibition caused by abiotic stresses. Compared to the non-inoculated control, the inoculated plants exhibited significantly increased plant height, above-ground and below-ground biomass, along with markedly reduced leaf relative conductivity and malondialdehyde content. Additionally, the activities of superoxide dismutase, peroxidase, and catalase, as well as the contents of proline and soluble sugars, were significantly enhanced (P<0.05). Moreover, root system architecture was notably improved. In conclusion, inoculation with B. paralicheniformis can significantly enhance the resistance of perennial ryegrass to drought, cold, and saline-alkali stresses by synergistically strengthening its antioxidant defense capacity, osmoregulatory function, and root morphological configuration., authors=YU Qiao1, WANG He-tong1, YANG Wan-qiang1, MENG Qing-xian1, ZHANG Yu-jing2, PUBU Zhuoma3, HU Tian-ming1, FU Juan-juan1, authorsList=YU Qiao, WANG He-tong, YANG Wan-qiang, MENG Qing-xian, ZHANG Yu-jing, PUBU Zhuoma, HU Tian-ming, FU Juan-juan, authorCompany=1 College of Grassland Agriculture, Northwest A&F University, Yangling, Shaanxi Province 712100, China;

    为探究植物生长促生菌对多年生黑麦草(Lolium perenne L.)抗旱、抗寒及耐盐碱能力的生理调控机制,本研究以副地衣芽孢杆菌(Bacillus paralicheniformis, NCBI ID: PRJNA1402526)菌株为研究对象,采用盆栽接菌试验,设置干旱、低温、盐碱三种非生物胁迫处理,分析根际接种该菌株对多年生黑麦草生长指标、生理特性及根系形态的影响。发现接种副地衣芽孢杆菌显著缓解了非生物胁迫对多年生黑麦草生长的抑制。与未接种相比,接种处理的株高、地上部和地下部生物量均显著提高,叶片相对电导率和丙二醛含量显著降低,超氧化物歧化酶、过氧化物酶、过氧化氢酶活性及脯氨酸、可溶性糖含量显著上升,且根系形态构型得到显著改善(P<0.05)。综上,接种副地衣芽孢杆菌可通过协同增强多年生黑麦草的抗氧化防御能力、渗透调节功能及根系构型,从而显著提高其对干旱、低温和盐碱胁迫的抗性。

    To investigate the physiological regulation mechanisms of plant growth-promoting bacteria on the drought, cold, and saline-alkali stress tolerance of perennial ryegrass (Lolium perenne L.), this study used Bacillus paralicheniformis (NCBI ID: PRJNA1402526) as the test strain. A pot inoculation experiment was conducted under three abiotic stress conditions-drought, cold, and saline-alkali stress—to analyze the effects of rhizosphere inoculation on the growth indices, physiological characteristics, and root morphology of perennial ryegrass. The results showed that inoculation with B. paralicheniformis significantly alleviated the growth inhibition caused by abiotic stresses. Compared to the non-inoculated control, the inoculated plants exhibited significantly increased plant height, above-ground and below-ground biomass, along with markedly reduced leaf relative conductivity and malondialdehyde content. Additionally, the activities of superoxide dismutase, peroxidase, and catalase, as well as the contents of proline and soluble sugars, were significantly enhanced (P<0.05). Moreover, root system architecture was notably improved. In conclusion, inoculation with B. paralicheniformis can significantly enhance the resistance of perennial ryegrass to drought, cold, and saline-alkali stresses by synergistically strengthening its antioxidant defense capacity, osmoregulatory function, and root morphological configuration.
