Abstract
Drought effects on the water loss by cuticular transpiration and alfalfa yield of twenty four alfalfa genotypes were evaluated. The experiment was conducted under vegetation house in 2006-2007 using special plots. Water stress was imposed before flowering by restricting watering, for 14 days. Exposure of plants to drought led to noticeable decreases in both leaf water loss by cuticle and biomass accumulation. There were significant negative correlations between water loss by cuticular transpiration and yield under water stress conditions for first and second year of alfalfa vegetation (r = -0.64*** , r = 0.62***), suggesting that low cuticular water loss could be used in selecting drought tolerant genotypes.
