Anise is an annual plant belonging to Apiaceae family and fruit essential oil of this herb is used in various pharmaceutical, cosmetic and beverage industries. Drought stress is one of the most critical limiting factors for anise production in worldwide. In this research, to finding interrelationships among different traits and performance, some anise genotypes were evaluated using the biplot m...
seedless barberry (berberis vulgaris l. var. asperma) is one of the few crops that is only cultivated in eastern parts of iran. as a new crop there has not been any study to identify phylogenetic relationships of this plant with other related species existing in iran. in this study, amplification fragment length polymorphism (aflp) markers based on four selected primer combinations (ecori/tru1i...
abstract the present study is concerned with the syntactic deviation in hafezs poetry. poems are known to be accompanied with various linguistic deviations. these deviations may be phonological, morphological and/or syntactic. the relatively high frequency of the cases of the syntactic deviation in hafezs poems makes this rhetorical feature as a main characteristic of his poetry. this thesis, ...
Breeders often use generation means analysis to obtain information about inheritance, gene action, and to determine effective breeding methods to improve important agronomic traits, especially under drought stress conditions. To investigate the genetic parameters of agronomic and morphological traits in durum wheat, a field experiment was carried out using F1, F2, BC1 and BC2 generations obtain...
to study the interaction effect of the salinity and salicylic acid on some morphological and physiological traits in clary sage (salvia sclarea), a pot experiment was conducted as factorial based on a completely randomized design with three levels of nacl and control (zero, 50, 100 and 150 mm), as the first factor and three levels of spraying the solution of salicylic acid and control (zero, 10...
1. Functional traits contribute to the success of invasive plants. These traits can reflect inherent properties or they can be new adaptations from evolutionary responses to escape from natural enemies of the introduced range. We tested the hypothesis that genetic shifts in morphological and physiological traits have occurred between native and invasive populations of Sapium sebiferum . 2. Sapi...
In order to evaluate the effect of foliar application of iron and magnesium nano-chelate fertilizers on morphophysiological characteristics of Vigna sinensis L., an experiment was conducted in Shahroud University of Technology in 2010-2011. The experiment was carried out in a factorial arrangement with randomized complete block design with three replications. Treatments included five levels of ...
Because sexual selection pressures are high in sexually dimorphic organisms, morphological, physiological and performance traits are often studied in a sexual selection context. The proximate mechanisms underlying evolutionary change in these traits, however, remain largely unstudied. Here, we examined the role of steroids in shaping morphology and physiological performance in males of a sexual...
In order to compare the efficiency of morphological traits and molecular markers in distinguishing the Consolida species, molecular analysis using nrDNA ITS and cpDNA trnL-trnF with maximum parsimony and Bayesian methods were done in a total of 34 species and forma representing 28 species of Consolida, 6 species of Aconitella, plus two species of Delphinium and two species of Aconitum as out gr...
the association between 140 microsatellite bands of 20 primer pairs and 13 quantitative traits recorded on 70 aegilops crassa from iran was evaluated. pearson’s coefficients showed significant correlations between some morphological traits. polymorphic information contents (pic) of loci were in the range of 0/16 (xgwm190) to 0/44 (xgwm161). the result of multiple regression analysis showed sign...
