Abstract

The effects of WATER DEFICIT on grain yield, yield components and the physiological characteristics of barley (Hordeu1Il vulgar L.) varieties were studied in a split plot design during the 1999-2000 growing season in Karaj, Iran. Five irrigation levels [0, 25, 50, 75, and 100% crop water requirements (CWR)] and six barley varieties KaroonxKavir , Reihani( drought tolerant), Torkman , C-74-9 (intermediate) , KavirxBadia and Gorgan-4 (2 rowed type, drought sensitive) were arranged in the main plots and sub plots respectively. Results showed that WATER DEFICIT induced stress and this decreased the grain yield and yield components. WATER DEFICIT increased the canopy temperature and those varieties showed a higher canopy temperature under. non-stress conditions, performed better. under drought conditions. Severe stress reduced the chlorophyll content (SPAD values) considerably, but the differences were not significant between the 50, 75 and 100% CWR treatments. In addition, no significant differences were observed in the chlorophyll content of barley varieties under drought conditions. The effect of irrigation on the photochemical efficiency of photosystem ll (Fv/Fm) and the other fluorescence parameters for all varieties were significant. Although the FvfFm values were not significant in barley varieties at any level of irrigation, in general Karoon x Kavir and Reihani varieties showed a better performance under WATER DEFICIT conditions. Proline content was significantly different in various irrigation treatments, but its accumulation at any level of irrigation did not differ significantly in barley varieties. It was concluded that the higher canopy temperature (less negative ~T) under well irrigated conditions and higher grain yield, 1000- grain weight, Fv/Fm values under water stress conditions could possibly be the proper criteria for screening the drought tolerant barley genotypes under field or laboratory conditions.
