To determine salinity-tolerant genotypes among the citrus germplasm present in Kotra collection, a greenhouse experiment was carried out as factorial, completely randomized design with three replications, at four levels of NaCl (0, 2, 4 and 6 dS/m) and 10 unknown genotypes, for 16 weeks. Cleopatra mandarin and Swingle Citromelo, as tolerant (control) and sensitive cultivars, respectively, were ...
Excessive application of P fertilizers, use of the bicarbonated water sources for irrigation concomitant to a low level of organic matter have resulted in widespread iron deficiencies in crop plants in Iran. One of the strategies to overcome this problem is to select tolerant genotypes to iron deficiency (i.e. iron-use-efficient genotypes) or bred genotypes with high-micronutrient-uptake abili...
BACKGROUND Haplotypes can increase the power of gene detection over genotypes and are essential to estimate linkage disequilibrium. METHODS Haplotyping was based on the minimum recombinant paradigm, whereby a phase is obtained only if it uniquely minimises the number of recombinants within a full sib family. Performance of this method was tested across three different data sets, consisting of...
Seed germination has an important role in the life cycle of plants and critical stages of the growth cycle, establishment and final yield. Seed germination is the most critical stage of seedling establishment which ultimately determines the successful production of the product. Salinity is one of the environmental factors reducing crop production in the world. Saline soils or irrigation the...
abstract prediction of death anxiety on the basis of demographic characteristics and sp پیش بینی اضطراب مرگ براساس ویژگی های دموگرافیک و مولفه های معنویت در سالمندان به کوشش الهام حسن زهی معنویت از جمله مفاهیمی است که سالیان متمادی در حوزه روان شناسی جایگاه خود را یافته است پیشینه پژوهش نشان داده است که با متغیرهای فراوانی در روانشناسی در ارتباط بوده است. هدف از پژوهش حاضر این اس...
abstract the first purpose of this study was to investigate the effect of consciousness-raising (c-r) activities on learning grammatical structures (simple present tense in this case) by iranian guidance school efl learners. the second one was to investigate the effect of gender on learning the simple present tense through c-r activities and tasks. finally, this study aimed to investigate the ...
in order to study the effect of trifluralin herbicide soil residues on growth and nodulation of chickpea genotypes, a greenhouse experiment was conducted at ferdowsi university of mashhad. a factorial experimental was conducted based on completely randomized design with three replications. treatments included of four genotyps of chickpea (hashem, ilc, kaka and kermanshahi) and seven concentrati...
Genetic divergence among 46 ash gourd genotypes from different origins was investigated to select the parents for hybridization using Mahalanobis D 2 statistics. Though the genotypes grouped into seven clusters, the pattern of distribution of the genotypes into different clusters were random indicating that the geographical isolation was not always related to genetic diversity. Characters like ...
The production of new and compatible cultivars to different environments is one of the most important goals for the breeders. The crossing new cultivars and the selection of superior genotypes for desirable traits among their offspring is a method that has always been used by breeders. 28 genotypes obtained from the crossing of a 7 × 7 one-way diallel experiment consisting of seven parents (Alv...
a module $m$ is said to be coretractable if there exists a nonzero homomorphism of every nonzero factor of $m$ into $m$. we prove that all right (left) modules over a ring are coretractable if and only if the ring is morita equivalent to a finite product of local right and left perfect rings.
