Abstract

An evaluation on the effects of DROUGHT STRESS on plant height, height of first capitul from land surface, capiltul diagonal, the number of the lateral branches, nucleus ratio to total seed, seed YIELD and OIL PERCENTage in SPRING SAFFLOWER was carried out in Research center of Agricultural and Natural Resources in East Azerbaijan, during 2007. The experiment was factorial including 2 safflower CULTIVARs (local in Arak-2811 and local in Isfahan) and 4 irrigation levels (non stress and DROUGHT STRESS during stem elongation, flowering and seed filling stages) based on complete randomized block design with 3 replications. The results indicated significant decrease by DROUGHT STRESS on plant height, height of first capiltul from land surface, capiltul diagonal, nucleus ratio to total seed and seed YIELD. The influence of irrigation cutting at stem elongation stage caused the plant height and height of first capiltul from land surface to be reduced; also DROUGHT STRESS affected on capiltul diagonal and nucleus ratio to total seed, and its decrease, by irrigation cutting at seed filling stage. Under the influence of DROUGHT STRESS the rate of seed YIELD was also reduced, which reached from 3263/5 kg per hectare at normal irrigation to 2388/5 kg per hectare by irrigation cutting at flowering stage squinty. The attained results showed that, the number of lateral branches and OIL PERCENTage weren’t affected by DROUGHT STRESS and that there was a significant effect between CULTIVARs about seed YIELD and OIL PERCENTage. Generally it can be concluded that Isfahan local CULTIVAR with average of 2978/75 kg per hectare having most seed YIELD excelled over Arak-2811 local CULTIVAR with average of 2735/66 kg per hectare, so is recommended.
