摘要

Soil salinization is a global challenge that severely limits agro-food production. Our approach to tackle this challenge involves using bioformulations containing halotolerant fungal endophytes to enhance plant tolerance against salinity stress. We evaluated the growth of Aspergillus sp. and Penicillium sp., two endophytic fungi, on culture medium with different NaCl levels. In greenhouse experiments using cucumber seedlings as model plant, we assessed the efficacy of our treatments. High NaCl concentrations in the culture medium stimulated hyphal growth but reduced sporulation and delayed spore germination. Cucumber seedlings treated with fungal bioformulations exhibited improved growth characteristics, higher chlorophyll content, as well as photosynthesis efficiency compared to control treatments. This plant-microbe association gives plant stress resilience through mitigating osmotic-deficit stress and provides a nutritional source for fungi. Our findings demonstrate that introducing halotolerant endophytic fungi in bioformulations is a sustainable approach in facing salinity.
