BACKGROUND AND AIMS Oilseed rape (Brassica napus) is an important oil crop worldwide. The aim of this study was to identify the variation in nitrogen (N) efficiency of new-type B. napus (genome A(r)A(r)C(c)C(c)) genotypes, and to characterize some critical physiological and molecular mechanisms in response to N limitation. METHODS Two genotypes with contrasting N efficiency (D4-15 and D1-1) w...
This study aimed to evaluate the genetic variability of the teak germplasm bank, using morphological traits and inter-simple sequence repeat molecular markers. Thirty clones were evaluated in a randomized complete block design with three replicates, and each plot was composed of three plants. A joint analysis of quantitative and qualitative variables was performed using the Gower algorithm. Qua...
Drought occurrence is one of the most important reasons for reduced yield in crops. At least in arid and semi-arid areas an efficient approach to tackle this problem is to identify and grow tolerant genotypes with the help of drought tolerance indices. The main objective of this research was to study the effects of drought on the performance of six genotypes of lentil in order to evaluate some ...
A factorial completely randomized block design experiment with three replications was carried out in greenhouse to evaluate cereal genotypic variation in phosphorus (P) acquisition and utilization efficiency in a calcareous soil with low available P (4.6 mg P kg-1 soil) and high total P (1260 mg P kg-1 soil). Treatments consisted of eight bread wheat (Triticum aestivum L.), three durum wheat (T...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
Zinc deficiency in crop plants has been recognized as a worldwide nutritional constraint. A greenhouse experiment was conducted with the objective of developing a screening technique to evaluate lowland rice genotypes for zinc use efficiency. Ten lowland (Oryza sativa L.) genotypes were tested at low (0 mg Zn kg) and high (10 mg Zn kg) zinc levels applied to an Inceptisol. Genotypes differed si...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
In this study, variation of beta-glucan content was assessed in 20 barley line and cultivars based on complete block design with three replications. Genetic diversity of these genotypes was also evaluated using ISSR markers. Beta-glucan extracted by an enzymatic method. Significant differences were found at the level of 1% among barley genotypes for beta-glucan content. The beta glucan content ...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
Background and Aims: In this study, the effect of rs310441 polymorphism in the human leukocyte antigen (HLA) region on the development of susceptibility or resistance to Type 1 diabetes (T1D) among the people with T1D compared to healthy subjects has been investigated. Materials and Methods: This research, which is based on the examination of 130 cases with T1D and 98 controls, has been carrie...
