The Macroalgal Biostimulant Improves the Functional Quality of Tomato Fruits Produced from Plants Grown under Salt Stress

Among the most perilous factors affecting tomato plant functioning and yield is salinity. The efficacy of halotolerant marine macroalgal extract Chaetomorpha antennina (Seaweed Extract—SWE) in mitigating toxic effects salt stress (150 mM) plants to promote enhance both functionality was tested. It evident that undesirably affected germination growth terms quality quantity. Treatment with SWE improved salt-strained by enhancing their indexes, morphological traits, photosynthetic pigments, as well protein phenol concentrations. also exerted a positive influence on protecting against increasing synthesis accumulation antioxidant enzymes, superoxide dismutase lipoxygenase along contents lycopene vitamin C. increased nutraceutical quality, flavour organolepty emerged fruits. GCMS analysis fruit pericarp showed siloxane, phenol, indole acetic acid compounds, aromatic benzene compounds. These results indicate potentiality induced toxicities prompting protective compounds such siloxane enzymes. noted plays crucial role promoting survivability improving functionality, nutrition, cultivation saline soils an eco-friendly sustainable manner.
