abstract in this study, two wild iranian crocus species (crocus speciosus and crocus cancellathus) were examined using 16 morphological characters and 13 issr primers on 250 and 25 plant samples, respectively. the highest and lowest coefficient of variations were belonged to the thickness of the petals (71.25%) and the leaf length (15.08%), respectively. cluster analysis based on morphological ...

“any science seeks generalities; the aim is to transcend knowledge of particular cases by discovering general regularities or laws” (chesterman, 2001, p. 1). these were the words of chesterman whose paper has served as a typical example of numerous papers carried out on ‘translation universals’ since the mid-nineties. blum-kulka (1986) is among translation studies scholars who proposed ‘explici...

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 ...

Evaluation of genetic diversity is the key principal for plant breeding, providing an opportunity to discover novel characters and alleles for breeders. In the present study, 69 durum wheat genotypes were investigated for genetic diversity using several inter-simple sequence repeat (ISSR) markers. Sixteen ISSR primers amplified a total of 163 fragments, which out 160 fragments were polymorphic....

Analysis of the extent and distribution of genetic diversity in crop plants is essential for optimizing sampling and breeding strategies. Several methods were identified for the existence of diversity in maize for the aim of perfect selection based on great diversity among maize genotypes. In this study, Inter-simple sequence repeat (ISSR) markers were used to assess genetic diversity in a sele...

the effectiveness of irap, remap, ssr, and issr markers were investigated to assess genetic diversity among and within eight medicago sativa l. populations. a total of 101, 119, 117 loci and 31 alleles were amplified using 10 irap, 14 remap, 16 issr and eight ssr primers, respectively. irap markers generated the maximum proportion of polymorphic loci per primer (pplp) while the maximum value of...

  Study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. Since the hybrid canola have more yield than inbred lines, determine the genetic diversity of this have particular importance. In the present study, genetic diversity among 36 genotype of Brassica sp. were determined using inter simple sequence repeat (ISSR) markers...

the purpose of this study was to examine the comparative effect of story retelling and role playing on efl learners’ vocabulary learning and reading comprehension. to carry out the purpose of the study 90 female learners of tabarestan language school located in noshahr were non-randomly selected. they took pet test and among these 90 participants 62 students were selected as homogenous learners...

ISSR markers were used to determine the genetic variation and sex determination of the three life-stages of 41 samples of Gracilaria corticata from two regions of the Persian Gulf and Oman Sea namely Bostaneh and Lipar. The specimens were cultured in PES media to observe the different life stages. DNA was extracted by modified CTAB method. After screening of 20 ISSR primers, four primers were s...
