Summary of Biostimulant – Modulation of Morpho-Physiological and Metabolic Profiles of Lettuce Subjected to Salt Stress and Treated with Two Vegetal-Derived Biostimulants
Biostimulant Effects on Lettuce: Enhancing Growth Under Salinity Stress
Biostimulant effects on lettuce are increasingly relevant as agriculture faces soil and water salinity challenges. High salt concentrations limit nutrient uptake, impair photosynthesis, and reduce yields. Protein hydrolysate (PH) biostimulants offer a sustainable approach to reduce these losses. Recent trials show that different formulations can support lettuce productivity under both control and saline conditions.
Biostimulant Effects on Lettuce Growth and Yield
A greenhouse experiment evaluated two PH products—Trainer (T) and Vegamin (V)—on lettuce grown at 0 mM NaCl and 30 mM NaCl. Researchers measured yield, mineral content, pigments, and polyphenolics. The study revealed notable improvements: yields rose by 8.9% (T) and 4.6% (V), while photosynthetic performance increased by 14% compared to untreated plants. These findings highlight how the effects of PH biostimulants on lettuce can depend on formulation.
Biostimulant Effects on Lettuce Under Stress
Trainer provided stronger benefits under salinity stress. It boosted the accumulation of protective compounds such as lutein (+39.9%), β-carotene (+23.4%), and flavonoids (+27.7%) relative to Vegamin. These molecules play a vital role in oxidative stress relief, helping plants sustain growth. This shows that lettuce response to biostimulants goes beyond yield, extending to stress tolerance and metabolic resilience.
Agricultural Importance of Biostimulant Effects on Lettuce
The research confirms that PH-based inputs can enhance lettuce growth, photosynthetic efficiency, and stress protection. For farmers, this translates into better profitability and more sustainable production practices. As agriculture adapts to challenging environments, understanding biostimulant effects on lettuce provides valuable insights for improving crop performance. Beyond lettuce, these results encourage broader adoption of biostimulants in vegetable production, reinforcing their role in sustainable farming strategies worldwide.
