A major source of photoassimilates deposited into the seeds is the closest photosynthetic source to the latter sinks. While the contribution made to grain yield by floral parts and the adjacent photosynthetic surfaces has been determined for a number of crop plants, such information lacks regarding safflower. Thus the present study was aimed at estimating the contribution of photosynthesis of s...
Safflower having oil with high unsaturated fatty acids is a very valuable plant. However the sensitivity of safflower to some pests as safflower fly (Acanthiophilus helianthi), particularly in drought stress conditions has limited its production. In order to evaluate the effect of drought stress on population density and damage of important safflower pests, especially safflower fly, an experime...
in order to evaluate the effect of water stress and plant density on growth and seed yield of safflower, a study was conducted during 2009 growing season at agricultural college of shiraz university. the experimental design was split plot based on randomized complete block design with three replications. the treatments were deficit irrigation (100, 75, and 50% of field capacity-fc) as main plot...
It is already known that secondary metabolites in plants are affected by many parameters such as biotic and abiotic stress conditions can vary quantity. Sorbitol, which used to increase osmolality cells, an important source of stress. The present study was conducted determine the effects sorbitol applications at different doses foliar spraying on total phenolic, flavonoid, antioxidant activity ...

drought is considered as the most important constraint to world’s crop production. furthermore arid and semiarid climate accounts for nearly most of terrestrial areas of iran. therefore in order to study the effect of irrigation regimes on growth, physiological attributes and grain yield as well as components of such a crop plant as safflower a 4-replicate split plot rcbd field study was perfor...
The aim of this study was to assess the potential bacterial antagonists to control Macrophomina phaseolina root-rot of safflower by using screening methods. In total, 38 fluorescent pseudomonads isolated from rhizosphere soil of healthy safflower plants were collected from major safflower growing areas, 13 were initially selected based on dual culture technique on potato dextrose agar media. Fu...
The hepatic synthesis of sterol was measured in the male Mongolian gerbil (Meriones unguiculatus) in vivo following the administration of [3H]water by monitoring the incorporation of radioactivity into digitonin-precipitable sterol. A diurnal rhythm in cholesterol synthesis was exhibited under conditions of ad libitum feeding with alternating 12-hour periods of light (0200 to 1400 hr) and dark ...
Littele is known about the relationships of different traits in safflower using wild and cultivated species. In this study, 46 safflower genotypes from five different species were evaluated under normal and deficit irrigation and the relationship of traits was assessed. Results showed that water stress had significant effect on head yield per plant, number of seeds per head, head diameter and 1...
