Abstract

In order to study the effect of WATER STRESS and MICRO ELEMENTS (B. Zn. S) on physiological aspects of RAPESEED varieties, 5 varieties, Hyola - 42, Syn1, Pf 7045.01, Symbol and Mohican, as a subplot have been studied under WATER STRESS and non stress condition (0, 25 and 75 percent of Fc) as main plot in split plot design with four replication on varamin. Results showed significant between irrigation treatment and varieties in pods per plant, grains in pod and yield. Between varieties most yield and yield component had been seen for Hyola 42 and lowest yield was for Symbol.1000 grain weight and another characteristics was effected by WATER STRESS, . there were no significant difference between varieties in response to Boron and Zinc in leaf dry matter. so there were in water deficit (O percent of Fc) treatment reduced than normal treatment reduced and showed significant difference between varieties in level %1 In split plot design, WATER STRESS Increased micro element concentration In leaved. Sulfur reduced from.0198 to.0101 and Zinc from 29.6 to 15.2 mg/kg of dry matter. Plant characters evaluated in this study were: Plant weight, number of pods per plant, number of grains per pod, 1000 grain weight, GRAIN YIELD, PERCENT OIL CONTENT and yield of oil. Analysis of data showed significant different cen between irrigation treatment and varieties in pods per plant, grains in pod and GRAIN YIELD. Between varieties the highest yield and yield component was for Hyola 42 (with 3377/5 Kg/ha) and lowest yield was for Symbol (with 1947 Kg/ha). 1000 grain weight and another characteristics was effected by WATER STRESS, so there were in water deficit (0 percent of FC) treatment reduced than normal treatment. and showed significant difference between varieties in level%1. In split plot design, WATER STRESS increased nitrogen concentration of %2.5 reached to %3.7 of leaved in dry matter. But decreased phosphor from 0/35% to 0/18% and Potassium percent from %2.73 reached to %1/09 in leaved dry matter. WATER STRESS (75%. 0% percent of FC) decreased GRAIN YIELD and OIL YIELD. GRAIN YIELD from 3340 Kg /ha decreased to (1788 Kg/ha) and OIL YIELD from (1343 kg/ha) reached to (753 kg/ha). cultivars were not significantly different in PERCENT OIL CONTENT. But WATER STRESS decreased PERCENT OIL CONTENT from %43/1 on %75 FC to %40/2 on %0 FC. In conclusion, differences is exist between RAPESEED cultivars and lines in response to WATER STRESS, and this may be due to different accumulation of compatible solutes, and physiological aspects example yield and yield component.
