To improve commercial grapevine cultivars, it is necessary to apply such methods that by cultivation of a certain number of vines in a certain area, higher yield could be harvested. To achieve such a goal, healthy stocks with resistant to pests and diseases, high fructification and high quality of vines are needed. All these properties can be obtained successfully through clonal selection. Viti...
به منظور بررسی اثرات تاریخ کاشت و سطوح تک‌آبیاری بر عملکرد ارقام مختلف گندم دیم، تحقیقی بر پایه طرح بلوک‌های کامل تصادفی و به صورت اسپلیت اسپلیت پلات در سه تکرار و به مدت دو سال زراعی (83–1381) در ایستگاه تحقیقات کشاورزی دیم، مراغه به اجراء در‌آمد. سه تاریخ کاشت (کرت اصلی) شامل: اوایل مهر، اواسط مهر و اواخر مهر، سه میزان تک‌آبیاری (کرت فرعی) شامل: بدون آبیاری (شرایط دیم)، تک‌آبیاری به میزان 50 ...
The positive and beneficial effects of mycorrhizal symbiosis on the growth of various plants have already been documented. Most arable crops can mutually establish symbiosis with endo-mycorrhizal fungi, however, mycorrhizal associations with almond (prunus amygdalus), particularly in calcareous soils of arid and semi-arid regions, have not been studied. Thus, to realize the symbiotic associatio...
Objectives: As the elderly population increases and their ability decreases, the need for nursing homes and formal caregivers becomes more significant. Caregivers are under the pressure and burden of care due to the provision of services. Therefore, the current study aimed to investigate the effect of cognitive-behavioral therapy-based social work intervention on the extent of care burden among...
Insects often leave the luscious flowers they frequent dusted in a coat of pollen, which bear to next bloom; insects and plants have struck mutually beneficial bargain. But some reneged on deal, sipping nectar from high using elongated mouthparts avoid carrying undue weight when pollen attaches their bodies limbs – has driven develop long pollen-bearing styles, protruding beyond anther, brush a...
Brown trout, Salmo trutta fario, has a wide range of distribution in the north of Iran and in Karaj, Lighvanchai and Karun Rivers, but there is no report about its feeding behavior in some water resources including the Lar Natural Park. In order to study feeding behavior of this fish during spawning season, a survey was carried out in the rivers of Elarm, Aab-Sefid, Kamardasht and Delichayi in ...
This study performs trend analysis of hydroclimatic varibles and their possible effects on the water resources variability. Nonparametric Mann-Kendall and spearman tests were used to investigate trend analysis of mean annual and 24-hr maximum rainfall, flood and low flow parameters of 23 hydrometery and 18 synoptic stations in Sefid-Roud basin. The results showed that mean annual and 24-hr rain...
Half diallel crosses of nine Iranian wheat cultivars were used to estimate the general and specific combining ability effects and other genetic parameters related to yield and its components. Parents with F2 generations were evaluated at Research Farm, College of Agriculture, University of Shahrekord, in a randomized complete block design with 3 replications. Partitioning of genotypes mean squa...
The above research evaluates the access and use of rural services of the villages in the province of Gilan, as examples of reducing inequalities and increasing the development. The method used in this article is applicable in terms of target, and cross-sectional in tems of identity. To do this research, morris model, indexing method, standardization and dividing by average are used. After compa...
In this study, an inversion method is conducted to determine the focal mechanism of Sefid-Sang fault by comparing interferometric synthetic aperture radar (InSAR) technique and dislocation model of earthquake deformation. To do so, the Sentinel-1A acquisitions covering the fault and its surrounding area are processed to derive the map of line of sight (LOS) displacement over the study area. The...
