to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...

In the present study we investigated the comparative genotoxic potential of laser rays and gamma rays on somatic and gametic cells of safflower (Carthamus tinctorius L.). Mutagenic parameters like mitotic and meiotic consequences were accessed from the plants that showed a linear relationship between dose absorbed and chromosomal anomalies. A wide spectrum of chromosomal aberrations was encount...

The present study investigated the effects of dietary cholesterol and monounsaturated and polyunsaturated fatty acids on plasma lipids and glucose concentrations. Four groups of ten male Wistar albino rats were fed diets of different fatty acid composition for 40 days. The control group consumed nonpurified diet (containing fat 3.7 g/100 g diet), and cholesterol, olive oil, and safflower oil gr...

Arabidopsis thaliana was transformed with a plastidial safflower glycerol-3-phosphate acyltransferase (GPAT) and an Escherichia coli GPAT. The genes were used directly and in modified forms with, as applicable, the plastidial targeting sequence removed, and with an endoplasmic reticulum targeting sequence added. Seeds of plants transformed using only the vector were indistinguishable in oil con...

abstract this reasearch was conducted to study the phenotypic diversity of thymus kotschyanus populations. seeds were collected from natural inhabitats (guilan, mazandaran, west azarbaijan, semnan and qazvin) and planted in qom reasearch station in 2007. a number of some such different morphological and phenological traits of the plants as plant,s height, leaf length, leaf width, oil content, i...

although wild safflower (c.oxyacantha, 2n=24) has not been studied to a very large extent, yet it is believed that it can be used as an important source of biotic and abiotic stress resistance genes for improvement of cultivated safflower (c.tinctorius l., 2n=2x=24). in this study, the crossability between these two (cultivated and wild safflower) species was evaluated as based upon morphology ...

Safflower is one of the economically important oil plants. There are some studies on safflower, but none its seed properties. This study was carried out in Biosystem Engineering laboratories Faculty Agriculture Bingöl University 2021. The seeds four different proprietary safflower cultivars were randomly sampled, and their physical properties examined under two separate groups, that is, control...
