Abstract

This experiment was conducted in 2000 to study the effects of four IRRIGATION INTERVALs on the seed yield and physiological indexces of three SUNFLOWER CULTIVARS. The experiment was performed on the experiment farm of Oil Seed Department, Seed and Plant Improvement Research Institute in Karaj. Cultivars were: Record, Golshid, and Hysun33. The IRRIGATION INTERVALs included; every seven, eleven, fifteen and nineteen days. The results indicated that with increasing IRRIGATION INTERVAL the PHYSIOLOGICAL INDEXES decreased. PHYSIOLOGICAL INDEXES including CGR, RGR, NAR in different cultivars had no differences. But LAI had a higher value in Hysun33 than other cultivars. Harvest index for this cultivar under water stress was higher affected less than other two cultivars. This cultivar produced a better yield even with use of less water. This might be -due to highest translocation during productive stage and grain filling. Cultivation (sowing) of this cultivar could give better yield by using less amount of water. It was concluded that these cultivars can be recommended to farmer.
