摘要
背景和目的土壤盐碱化阻碍了作物的生长和产量，对农业构成了重大挑战。方法将向日葵幼苗分别接种 Glomus mosseae（丛枝菌根真菌）和 Pseudomonas fluorescens（植物生长促进根瘤菌），并将其混合接种，然后将其置于盐度（150 mM）下 60 天。结果盐胁迫导致向日葵叶片营养失衡，促进氧化损伤，降低光合效率，并诱导相容性溶质和抗氧化剂的积累。生物肥料处理有效缓解了盐胁迫的不利影响。接种植物在盐度胁迫下表现出生长旺盛、养分和光合色素含量较高。在接种植物中，胁迫对光合量子产率的不利影响明显减弱。接种植株的抗氧化活性和类黄酮含量增加，H2O2 和 MDA 以及电解质渗漏随之减少。结论我们的研究结果表明，联合施用 G. mosseae 和 P. fluorescens 能最有效地减轻盐胁迫对向日葵幼苗的有害影响。基于这些结果，使用 G. mosseae 和 P. fluorescens 作为生物肥料提供了一种可持续的生态友好型策略，可提高作物对盐分有害影响的耐受性。
Biofertilizer-mediated salt tolerance in sunflower: synergistic effects of Glomus mosseae and Pseudomonas fluorescens
Background and aims
Soil salinization poses a significant challenge to agriculture by hindering crop growth and yield. The present study aimed to examine the potential of two biofertilizers to mitigate the adverse effects of salt stress on sunflower plants.
Methods
Sunflower seedlings were inoculated with Glomus mosseae (arbuscular mycorrhizal fungi) and Pseudomonas fluorescens (plant growth-promoting rhizobacteria) individually, as well as in combination and exposed to salinity (150 mM) for 60 days.
Results
Salt stress led to nutrient imbalance, promoted oxidative damage, reduced photosynthetic efficiency, and induced accumulation of compatible solutes and antioxidants in sunflower leaves. Biofertilizer treatments effectively alleviated the detrimental effects imposed by salinity. Inoculated plants exhibited promoted growth, and higher nutrient and photosynthetic pigment content under salinity stress. In inoculated plants, the adverse effects of stress on photosynthetic quantum yields were significantly attenuated. Antioxidant activity and flavonoid content increased in inoculated plants followed by a reduction in H2O2 and MDA, and electrolyte leakage. A higher accumulation of compatible solutes was stimulated in salt-stressed sunflower plants by the biofertilizer treatments.
Conclusions
Our results demonstrated that the combined application of G. mosseae and P. fluorescens was the most efficient treatment in diminishing the harmful impacts of salt stress on sunflower seedlings. Based on these results, the use of G. mosseae and P. fluorescens as biofertilizers offers a sustainable and eco-friendly strategy to increase crop tolerance against the deleterious impact of salinity.
期刊介绍：
Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
