Effect of Water Stress on Proline Content and Growth of Strawberry

Abstract

Effect of water stress conditions for 10 days under drought and waterlogging at the flowering and fruit setting stages were investigated on the proline content in leaves, growth response and yield of strawberry cv. ‘No. 70’ The results indicated that, during the sudden drought stress of strawberry in clay pots on proline content increased 57.76-fold at fruit setting stage. The growth response and percentage of fruit set under drought regime were not differed from the controls, however increasing of total soluble solids more than those of the controls. Under waterlogging condition at fruit setting affected to increase 5.53-fold of proline in leaves when compared with the controls, whereas, it caused a reduction in fruit set to 39.31%, fruit size and ascorbic acid content.
