Chemical Composition and Bioactive Properties of Purple French Bean (Phaseolus vulgaris L.) as Affected by Water Deficit Irrigation and Biostimulants Application

Biostimulants are a novel and eco-friendly agronomic tool with practical applications in alleviating negative effects of environmental stressors. The present work studied the three biostimulant products (Nomoren (N), Twin-Antistress (TW), X-Stress (XS)) under normal irrigation (W+) water deficit conditions (W−) on nutritional, chemical composition bioactive properties common bean fresh pods. A variable effect biostimulants was observed nutritional value parameters, while fructose sucrose were main detected sugars, especially NW+ CW− treatments. Oxalic, malic, citric acid organic acids, γ- total tocopherol content highest TWW+. (+)-Catechin (−)-epicatechin most abundant phenolic compounds, NW− treatment. antioxidant capacity for Thiobarbituric Acid Reactive Substances (TBARS) Oxidative Haemolysis assays (OxHLIA), TWW+ extracts showed best overall results against tested fungi. In conclusion, had positive bioactivities purple depending regime.
