structure. So, it is possible to achieve the salinity-tolerant genotype in plants through creating changes in the genetic structure and breeding activities. Tomato is in the group of plants sensitive to salinity stress. Distinct studies have been explained different indicators for tolerance to salt stress in tomato. Identifying a reliable indicator in the early stages of plant growth under salt...
the subjects of the study are only the tefl teachers and students at gilan university. to obtain the desired data, a questionnaire which was based on the theories and disecussions gathered, was used as the main data gathering instrument. to determine the degree of relationship between variables, covariance and pearson product moment correlation coefficient were the formulas applied. the data we...
In the present investigation, an attempt has been made to evaluate the genetic variability of yield contributing characters, and the genetic diversity in forty-four genotypes of okra collected from the IIHR, Bangalore, India. Analysis of variance indicated significant differences among the genotypes for different morphological characters. High GCV and PCV were observed for plant height, inter-n...
the genetic diversity of a large number of pistachio genotypes grown in iran is not exactly known. most of the studies on genetic diversity of iranian pistachio varieties are based on morphological characteristics or isozyme markers. in the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by amplified fragment length polymorphism (...
this study was carried out to investigate the important characteristics in some cultivars/genotypes of persianwalnut (juglans regia l.), black walnut (j. nigra l.), and walnut inter-specific hybrids: paradox (j. hindsii × j.regia) and royal (j. hindsii × j. nigra) in kamalshahr research station in karaj in 2011-2012. in the study,vegetative vigor was evaluated based on trunk cross-sectional are...
abstract the present study was conducted in order to investigate the impact of an integrated model of form-focused and task-based instruction on iranian efl learners vocabulary learning and retention.it also aimed to detect efl learners attitude towards the implementation of form-focused task-based vocabulary instruction in the classroom. in order to address the purposes of this study, a sampl...
ziziphora tenuior, named kakooti in farsi, is one of the aromatic and medicinal plants of a wide distribution in iran. in this study, rapd molecular markers, (by utilization of 16 primers) was applied to determine the genetic diversity of 39 samples of ziziphora tenuior from 21 geographical regions in iran. a number of 100 polymorphic bands out of 110 amplified ones was produced and analyzed th...
background and objectives: citrobacter freundii is an opportunistic pathogen causing nosocomial infections and resistant to various antibiotics. we aimed to determine the clonal relationship of c. freundii isolates using pulsed-field gel electrophoresis (pfge). materials and methods: fifty clinical isolates of c. freundii were collected from the main hospital in kermanshah. after antibiotic sus...
Late spring frost usually damages flowers and reduces yield of almond trees. Due to natural sexual reproduction, in most of almond orchards of Qazvin province, Iran, which have been established through seedling propagation, a vast genetic variation has been occurred. This situation has been provided many possibilities to study different traits of native almond genotypes, to select superior geno...
