background and objectives: seed vigour is the resultant of a broad range of physiological processes which have genetic background. the study of genetic variation, play an important role in enhancing the ability of breeders in selection and breeding operation. this study aimed to evaluate rice genotypes with the physiological and morphological characteristics related to seed vigour and grouping ...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...

in order to determine the genetics of barley lines for freezing resistance based on crown survival percentage an experiment was carried out as a split plot design on the basis of randomized complete blocks with two replications. forty barley lines were assigned in subplots and five freezing temperatures (-8, -11, -13, -15 and -17 ˚с) were allocated in main plots. the results showed significant ...

BACKGROUND: Seed aging is an important problem in developing countries which seeds stored in inappropriate condition. OBJECTIVES: Current research was carried out to study the effect of seed aging on quantitative parameters of wheat seeds (Chamran cultivar). METHODS: Experiment was carried out based on randomized complete block desi...

To study drought stress on seedling dry weight, proline contents and evaluate of antioxidant enzymes activity in canola genotypes (Brassica napus l.), an experiment were evaluated at laboratory physiology, Shahed University. This experiment was carried out in factorial with CRD design with 4 replications in 2008. The first factor was including levels of dough stress, one without stress as check...

a pot experiment laid out in factorial arranged in completely randomized design with three replications was implemented to evaluate the effects of seed priming in ameliorating salinity stress in sesame (sesamum indicam l.) during seedling development and the early vegetative growth. factors included five priming treatments : control (non priming) , hydropriming, halopriming with nacl, kcl , cac...

Effects of cold plasma treatment on soybean (Glycine max L. Merr cv. Zhongdou 40) seed germination and seedling growth were studied. Seeds were pre-treated with 0, 60, 80, 100 and 120 W of cold plasma for 15 s. Results showed that plasma treatments had positive effects on seed germination and seedling growth, and treatment of 80 W had the highest stimulatory effect. Germination and vigor indice...
