in order to evaluate the physiological indices in relation to the screening of spring safflower genotypes for drought tolerance and productivity, seed and oil yields and yield components were measured for five genotypes including local arak, local esfahan, sina, kh23 – 57 and goldasht. the study was conducted in a loam soil in east azarbaijan, iran, during three successive years (2005-2007)...

seed and oil yields, its components and two physiological indices including leaf canopy temperature (tc) and relative water content (rwc) were evaluated in two spring oilseed rape cultivars (rgs 300 and hyola 401) under non-stressed and water deficit imposed during stem elongation, flowering and seed filing stages. the experiments were conducted as a factorial consisted of 2 factors including i...

safflower as an original crop in iran has high adaptability to different environmental conditions. iran is one of the original areas of safflower as a drought and salinity tolerant crop. therefor, safflower can be a suitable alternative crop for cultivation in marginal areas. the aims of research were studying the late season drought effects on seed and oil yields and its components of fall saf...

seed and oil yields, their components, and the relationships among trait performance were determined in 25genotypes of winter type oilseed rape (brassica napus l.). the experiment was carried out at the agricultural and natural resources research center of east azerbaijan, iran, in two consecutive growing seasons 2009-10 and 2010- 11. significant differences were observed in plant height, numbe...

safflower oil seed has high adaptability to different kinds of abiotic stresses such as drought and salinity. the aim of this study was to evaluate the effects of drought stress at different phenological stages on relative water content (rwc), leaf canopy temperature, seed yield and its components in spring types of safflower. the study was carried out in east azarbaijan research center for agr...

two field and laboratory experiments were conducted to investigate the effects of superabsorbent polymer (sap) and irrigation management on seed and essential oil yields of cumin, as well as the impact of water quality on water holding capacity of sap. salinity had a negative effect on the amount of water absorbed by sap (335 and 59 g h2o per g sap, for distilled water and solution of 0.5% nacl...

the stability of ten winter safflower cultivars and lines was evaluated in three different environmental conditions in karaj, isfahan and darab in iran, a randomized complete block design with 4 replications over three years (1995, 1996 and 1997). simple analysis of variances of grain and oil yields from each experiment showed significant differences among the genotypes. after conducting a homo...
