Abstract

To determine the stability of grain weight using CHEMICAL DESICCATIONS and to sudy the gas relations in different advanced BARLEY lines, this study was carried out during 2002-2003 growing season at Ghamloo Agricultural Research Station in Kurdistan province. A split plot with two main plots (rainfed and irrigation), 24 sub plots (different BARLEY GENOTYPEs), with three replications was applied. Ten days after anthesis in irrigated plots, by spraying NaCLO3 0.4% on shoot organs, photosynthesis was disordered. In rainfed plots RELATIVE WATER CONTENT (RWC) was measured. Using IRGA, advice gas paremeters in rainfed and irrigated plots was also counted. The grain weight of all lines was reduced under spraying. There was positive and strong correlation between grain weight reduction in sprayed and rainfed conditions (r = 0.7**). Based on SSI (Stress Susceptible Index), three groups (tolerant, susceptible and medium) was indicated. Except water use effeciency, all gas parameters were reduced under rainfed, but this reduction was less in tolerant lines than those of susceptible lines. No significant difference was observed between tolerant and susceptible lines in RWC.
