Chaste plant extract is a promising biostimulant for tomato plants' growth under salt stress

Temperature change, global warming, and the ever-changing climate have made life extremely difficult for plants. Our research analyzed the effects of chaste plant extract on salt-stressed tomatoes. Three concentrations of chaste plant extract (CPE) were applied (0.25%, 0.5%, and 1%). The obtained results indicated that CPE-treated plants showed a higher ability to tolerate salt stress (75 mM) by a significant increase in plant growth and photosynthetic pigment content (p <= 0.05). Antioxidant enzyme activities such as superoxide dismutase (SOD), isocitrate dehydrogenase (ICDH), glutathione peroxidase (GPx), and glutathione reductase (GR) are also crucial in the case of treatments. Carbon-nitrogen enzymes such as phosphoenolpyruvate carboxylase (PEPC), malate dehydrogenase (NAD-MDH), and glutamine synthase have changed (GS). Our results suggest that the application of chaste plant extract could be used as a promising plant growth biostimulant for treating tomato plants under salinity stress.

Automated summary

Temperature change, global warming, and climate variability have adverse effects on plant growth. Our research suggests that chaste plant extract can enhance the salt tolerance of tomato plants, promote growth and photosynthesis. Antioxidant enzymes and carbon-nitrogen enzymes play crucial roles in this process.
