The physiological response of wheat plants to exogenous application of gibberellic acid (GA3) or indole-3-acetic acid (IAA) with endogenous ethylene under salt stress conditions

Wheat (Triticum vulgaris) plants were grown without NaCl and under salinization levels of NaCl. Salinity decreased the fresh, dry matter, water content, length and leaf area. Phytohormonal treatments with gibberellic acid (GA3) or indole-3-acetic acid (IAA) caused a marked increase in these parameters; GA3 was more effective than IAA. This activation was concomitant with the increase of osmotically active solutes,...

Role of gibberellic acid (GA3) in improving salt stress tolerance of two wheat cultivars

Several environmental factors adversely affect plant growth and development and final yield performance of a crop. Drought, salinity, nutrient imbalances and extremes of temperature are among the major environmental constraints to crop productivity worldwide. Gibberellic acid (GA3)treatment has alleviated the drastic effect of salinity in growth parameters (leaf area, dry weight of grains and photosynthetic...
