Biostimulants Boost Tomato Resilience to Salinity, Offering Hope for Climate-Resilient Crops
August 12, 2024A recent study investigated the use of biostimulants, specifically arbuscular mycorrhizal fungi (AMF) and compost, to enhance tomato tolerance to salinity in a greenhouse setting.
Tomato seeds were treated with AMF, compost, or a combination of both under saline conditions, revealing that salt stress negatively impacted key growth parameters.
Results indicated that Fm inoculation significantly improved mycorrhizal colonization rates and root development under saline-alkaline stress compared to Ri.
Under saline-alkaline stress, Fm-inoculated plants exhibited better overall growth, photosynthetic pigment accumulation, and lower lipid peroxidation levels than non-mycorrhizal controls.
Both AMF and compost enhanced photosynthetic pigment concentrations and protein content, contributing to improved plant resilience under salt stress.
Salinity significantly challenges the development and metabolism of tomato plants, affecting growth metrics such as height, number of flowers, and fruit production.
As climate change increases soil salinity, finding crops that can thrive in these conditions is essential.
While salt-tolerant tomatoes may not be available soon, the research is a significant step toward a more resilient agricultural system.
Research highlights the potential of biostimulants to mitigate salinity effects, suggesting a sustainable approach to improve agricultural practices amidst climate change challenges.
The study is rooted in the context of rising global food demands, projecting a need for significant increases in agricultural production by 2050.
Endophytes, which live within plant tissues, provide benefits such as growth promotion and pathogen resistance, enhancing overall plant health in challenging conditions.
The findings support the potential use of black wolfberry and AMF in agricultural practices aimed at mitigating the effects of soil salinization in arid regions.
