چکیده
The main source of seed filling results from the photosynthesis green tissue closest to sinks in capitula. To evaluate role different leaf strata and capitula yield its components Safflower genotypes, a field study was performed as factorial experiment based on RCBD 3 replicates East Azarbaijan Agricultural Natural Resources Research Education Center 2008. used factors this were: two genotypes including (Mahalli Esfahan Goldasht) defoliation five levels: plants lower 1/3, middle upper 1/3 stem, capitulum covered with aluminum paper control (without defoliation). showed that did not affect plant height number pods. But, there highly significant difference between terms seeds per pod, plant, 1000 weight, oil percentage yield. interaction genotype×strata treatments harvest index significant. Among treatment levels both highest decrease compared were observed levels, whereas lowest level. rate reduction Mahalli higher than Goldasht. change Goldasht mostly due changes head. In addition, net photosynthesis, area, contribution ones higher, removal had effect through total whole plant. Also, covering caused So, head has major

Effect of plant growth regulators on oil yield and biodiesel production of safflower (Carthamus tinctorius L.)
The aim of the present investigation was to determine the effect of plant growth regulators viz., kinetin, chlorocholine chloride (CCC) and salicylic acid (SA) on achene yield and oil quality of safflower (Carthamus tinctorius L.) cv. Thori pertaining to biodiesel production. The growth regulators were applied at 10M as foliar spray during flowering (140 days after sowing). Kinetin was highly e...

Abstract Safflower is a minor oilseed crop in Australia where the market is dominated by canola, cottonseed and sunflower. Safflower however offers an alternative oilseed crop in marginal areas. This study was designed to evaluate current safflower lines and to determine their potential value both for edible oil and meal for animal feed. Two sets of samples were analysed. The first was a collec...

Nitrogen fertilizer management has a special priority for safflower economic production. Increasing the efficiency of this element, in addition to increasing economic benefits, also reduces environmental pollution. Therefore, a factorial experiment was conducted in the form of statistical design of complete randomized blocks with three replications at Safiabad Agricultural and Natural Resources...
