Damage caused by water shortages leads to physiological and biochemical changes in metabolism of plants and make them predispose to attack by pests and diseases and reduce the quality of the crops. In order to evaluate the effect of supplemental irrigation on safflower fly (A. helianthi) population of safflower cultivars, an experiment conducted as a split plot based on randomized complete bloc...

considering high alkalinity of iranian soils and lack of availability of some nutrients in those conditions, sulfur consumption is one approach to increase the availability of insoluble nutrients especially in calcareous and alkaline soils. effectiveness of sulfur depends on activity of sulfur oxidizing bacteria especially thiobacillus genus (t). in order to study the qualitative yield and morp...

safflower (carthamus tinctorius l.) of the family asteraceae is an annual broadleaf oilseed crop with 35-40 % oil. it was originated from southern asia and is known to have been cultivated in china, india, iran and egypt. in iran the safflower cultivation area has increased over 10000 ha in 2008. some pathogenic fungi such as pythium ultimum, phytophthora drechsleri, puccinia carthami, and fusa...

this study carried out to determine the differences between oil content and fatty acid compositions of 12 exotic and 6 local safflower genotypes. the experiments were arranged in randomized complete blocks design with three replications in research station of ferdowsi university of mashhad. the results of variance analysis showed that the differences of seed yield, oil content and fatty acid co...

Safflower is an important, traditional, multipurpose oil crop. This was to investigate the effect of different salinity levels on morphological, physiological, biochemical and antioxidant response of two safflower cultivars (Carthamus tinctorius L. cultivar TSF1 and cultivar SM) differing in salt tolerance. Salinity stress (0.0%, 1.0%, 1.5% and 2.0% of NaCl) was induced to safflower plants afte...

abstract the overall purpose in this study was to investigate extensional- educational factors that influencing on transgenic plants usage. the research design of the study was a survey utilizing descriptive-correlation technique. the target population consisted of 85 biotechnology experts at research institutes of tehran province which were studied by a census study (n=85). finally 63 experts ...
