Agronomic and Photosynthetic Characteristics of Different Maize Hybrids in Response to Water Deficit Stress at Different Phenological Stages
The aim of present study was to evaluate the effects of drought stress on net photosynthesis rate (Pn), stomatal resistance, water use efficiency (WUE) and biomass (BM) of six maize (Zea mays L.) hybrids. Drought stress applied by withholding water supply at 4-5 leaf stage (S1, vegetative stage), anthesis (S2, reproductive stage), and dual stress condition (S3, combination of vegetative and rep...
متن کاملModeling the response of peach fruit growth to water stress.
We applied a semi-mechanistic model of fresh matter accumulation to peach fruit during the stage of rapid mesocarp development. The model, which is based on simple hypotheses of fluid flows into and out of the fruit, assumes that solution flow into the fruit increases with fruit weight and transpiration per unit weight, and decreases with the maximum daily shrinkage of the trunk, which was used...

متن کاملEffects of Deficit and Cutoff Irrigation During Different Phenological Stages of Fruit Growth on Production in Mature Almond Trees cv. ‘Mamaei’
Regulated deficit irrigation (RDI) is commonly used during different phenological stages of fruit growth and development in almond trees to reduce the amount of irrigation water applied without or with only very small reductions in yield. Therefore, to study the effects of deficit and cutoff irrigation during different phenological stages of fruit growth and development in almond cv. “Mamaei” p...
