Nutritional effects of salt stress on mycorrhized tomato (Solanum lycopersicum L.) plants
Main Article Content
Abstract
Soil salinity is one of the most widespread agricultural problems, inhibiting plant growth and productivity. Arbuscular mycorrhizal fungi (AMF) are considered an effective alternative for the biological improvement of salinity stress, the objective of this work being to determine the effect of inoculation with different strains of AMF on the nutritional status of tomato plants under salt stress conditions. In the experiment tomato plants (Solanum lycopersicum L.) of the Vyta variety were used, studying the effect of the inoculation of different strains of AMF and three different levels of salinity on the nutritional status of the plants. It was observed that the plants inoculated with the AMF strains had a better nutritional status, both under normal conditions and under salinity stress, with a notable decrease in sodium content in plants colonized by said strains under salinity stress conditions.
