| Popis: | In this experiment, the effects of two deficit irrigations (DI50, DI75) and full irrigation (FI100) together with control (Rainfed) treatment were evaluated. Irrigation was started when the midday leaf water potential reached −10 bars. Accordingly, irrigation was initiated after berry set and continued at weekly intervals until harvest time in the study area. To calculate water volumes applied to the irrigated plots, 50%, 75% and 100% of the cumulative evaporation from the class A pan for a week were considered. Considering gibberellic, salicylic and abscisic acid, organic acids, macro and micro elements, ‘Carignane’ had lower values than those of ‘Semillon’. The amount of fructose, xylose and arabinose were higher in ‘Carignane’. The amounts of all hormones, carbohydrates, organic acids and macro and micro elements were generally higher in control and DI50 treatments. But, no significant differences were found between irrigation levels considering hormones, indole acetic, citric, maleic and succinic acids. As a result of the study, it can be concluded that the amounts of compounds in the grape seeds increased with rainfed and deficit irrigation together with the rainfall under experimental conditions. |
