Abstract

The recognition of physiological relations is important for the analysis of factors which affect yield and its components of SAFFLOWER. YIELD COMPONENTS are affected by the management, genotype and the environment. They help researchers to recognize the reasons for the increase or decrease of yield too. Five SAFFLOWER genotypes, including two chosen lines from Esfahan SAFFLOWER landrace and cultivars Arak 2811, Gilla and Kooseh, were compared at two seeding dates (April 4 and July 6) and three planting densities (40,20 and 13 plants per square meter). The planting date had significant effects on the yield, YIELD COMPONENTS and other PHYSIOLOGICAL CHARACTERS, except the oil percentage. Head per plant, seed weight, seeds per plant and plot and plant yield in spring planting were higher than SUMMER PLANTING. Plant and plot yield, YIELD COMPONENTS, seed per plant and seed pith percentage were affected by the planting density. The mean comparison of this characters showed a decrease in planting density due to increased heads per plant, seed weight, seeds per plant, pith percentage and plant grain yield, but decreased seeds per head and plot grain yield significantly. Genotypes were showed to have significant differences in physiologic characters and YIELD COMPONENTS. Heads and seeds per plant, pith and oil percentage, harvest index and plot and plant grain yield in line 1 were clearly higher than other genotypes. The result of stepwise regression for the grain yield estimation shows that heads per plant described 73% of variation in seed yield. Seed number per head, total grains of plant number of days from planting to physiologic ripening and harvest index explained 8.7, 5.4, 5.0 and 1.5 percentage of seed yield variation, respectively.
