Abstract

In other to investigate the effects of WATER DEFICIT on YIELD and PHOTOCHEMICAL EFFICIENCY OF PHOTO SYSTEM II of BARLEY varieties, an experiment split plot based on randomized complete block design with three replications was conducted in Farm Seed and Plant Improvement Institute Karaj in 2002. In this study the main plots were irrigation in five levels (0, 20, 50, 75 and 100 % of plant water requirement) and sub–plots were barely varieties (Torkaman, Karon×kavir, Rihany, C-74-9, Ghorghan-4, Kavir×Badia). The result showed that WATER DEFICIT caused an decreased in temperature of canopy, however varieties with warmer canopy under control treatment were tolerant to drought and showed higher YIELD than other varieties under drought condition. In WATER DEFICIT treatment, PHOTOCHEMICAL EFFICIENCY OF PHOTO SYSTEM II (ratio of Fv/Fm) declined significantly due to increasing of Fo and ultimately decreasing of Fv. WATER DEFICIT affected significantly on YIELD and YIELD components and it caused an decrease in all of their, although there was significant different among varieties under WATER DEFICIT.
