root rot disease of broad-bean caused by fusarium solani is a serious disease of this crop. due to high cost and difficulty of the disease control, interaction between root nodulating bacteria and fusarium. solani were evaluated to use for disease management. broad-bean root nodulating bacteria were isolated and their interaction with f. solani was investigated in culture medium in a completely...

abstract arsenic (as) contamination of soils is a global problem. legumes are often used in remediation of contaminated sites because of their capacity to fix nitrogen. in the present study, the effects of inoculation of bean (by rhizobium leguminosarum bv. phaseoli) on plant uptake and tolerance to arsenic were investigated. an experiment with a factorial arrangement, two levels of inoculation...

the evaluation of gene bank germplasm collection for morpho-physiological traits is important in the breeding programs. although phenotypic variation was considered, it is likely that this phenotypic variation is largely genetic and therefore directly useable for breeders, especially for those traits with high heritability such as heading and maturity time, plant height, kernel number and weigh...

A complete diallel cross using eight flax genotypes including four Iranian breeding lines and four Canadian genotypes was carried out to estimate genetic parameters for days to flowering, days to maturity, plant height, primary branches per plant, number of capsules per plant, number of seeds per capsule, seed yield per plant, 1000-seed weight, seed yield and harvest index. Analysis of variance...

The possible toxicity of a commercial chlorine dioxide preparation (Halox E-100) was evaluated on radish and lettuce seedlings growing in pots under controlled conditions. A single application of various dilutions to radish seedlings growing in a sterile or nonsterile commercial plant substrate only slightly decreased plant dry weight. At the end of the experiments, the plants appeared unaffect...

In this study, plant height and plant dry weight of five wheat varieties (namely Da da 94, K nac 97, Konya 2002, Karahan 99 and Ahmeta a), collected for 20 weeks, were modeled via fitting generalized logistic (GLC), logistic (LC) and Gompertz (GC) growth curves. Growth curve selection was based on residual sum of square (RSS) and mean square error (MSE). Following growth curve selection, growth...

genetic variation of 20 genotypes (15 exotic collected from icarda, and 5 endemic collected from various regions of iran: ardebil, oshnaviyeh, qazvin, shahre kord and mashhad) were studied during the 2007-2008 growing season, using morphological and phenological traits. the resultant data were examined for normality test and were then analyzed according to randomized complete block design (rcbd...

Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...
