Use of Microbial Biostimulants to Increase the Salinity Tolerance of Vegetable Transplants

Vegetable plants are more sensitive to salt stress during the early growth stages; hence, availability of poor-quality brackish water can be a big issue for nursery vegetable industry. Microbial biostimulants promote and vigor counterbalance in mature plants. This study aimed evaluate application plant growth-promoting microorganisms improving tolerance lettuce tomato seedlings irrigated with different salinity levels (0, 25, 50 mM NaCl) growth. Two commercial microbial were applied substrate before seeding: 1.5 g L?1 TNC BactorrS13 containing 1.3 × 108 CFU g?1 Bacillus spp.; 0.75 Flortis Micorrize 30% Glomus spp., 1.24 Agrobacterium radiobacter, subtilis, Streptomyces spp. 3 105 Thricoderma Many morpho-physiological parameters suffered negative effect salinity. The use modified seedling its response stress. They had on unstressed increasing fresh dry biomass accumulation, leaf number, area successful especially when using Micorizze that enhanced up NaCl. inoculation could represent sustainable way improve transplant quality nurseries limiting
