Abstract

The effect of DROUGHT STRESS on some morphological, physiological and biochemical responses of five grapevine cultivars (Gazney, Shahani, Muscat Gordo, Flame Seedless and Bidaneh Sefid) was evaluated. One year old rooted cuttings of each cultivar were used in a factorial experiment with complete randomized blocks design, under different levels of water deficit (80%, 50% and 30% of soils available water) using gypsum blocks, in green house condition. The results showed that the plant height, number of leaves and nodes, leaf area and the percent of dry weight related to each cultivar decreased with increasing water deficit rate. The highest decrease observed in 30% of soil available water treatment. Decreasing in plant height was significant only in Flame Seedless cultivar. The highest PROLINE accumulation occurred in Muscat Gordo and SOLUBLE CARBOHYDRATES accumulated most high in Gazney cultivar under 30% available water treatment. Flame seedless had the lowest level of PROLINE, SOLUBLE CARBOHYDRATES and CHLOROPHYLL content. Gazney and Shahani cultivars showed no significant decrease in CHLOROPHYLL content under water deficit stress. The relative water content (RWC) of leaves decreased due to water deficit. The highest decrease observed in Gazney and Bidaneh Sefid. There was negative correlation between RWC and PROLINE accumulation. The cultivars Gamey followed by Bidaneh Sefid and Shahani and then Muscat Gordo had better relative growth rate respectively under water deficit stress, but Flame Seedless was the most sensitive cultivar to this condition and is not recommended for cultivation in arid areas.
