apricot ( armeniaca vulgaris l.) is a popular and an economically profitable fruit of the temperate zone. various apricot genotypes grow in different areas in iran. the genetic diversity of 30 cultivars and genotypes of iranian apricot and as well, of two foreign cultivars (as control) was studied through morphological attributes and rapd markers. in a first experiment, 21 quantitative and qual...

in this research work, genetic diversity of 21 wild persian shallot (allium hirtifolium boiss.) accessions from south, southwest, west and center of iran was evaluated using morphological traits as well as aflp markers. results showed that khansar accession had the highest leaf width (5.42 cm), mean leaf number per plant (5.41), bulb diameter (10.84 cm), bulb height (4.95 cm) and mean bulb weig...

eight pollinators (as pollen parents) and four cms lines (as seed parents) differing in salinity and drought tolerance were evaluated using agro-morphological traits and microsatellite markers. root yield, leaf weight, sugar content, sodium content (na+), potassium content (k+), a-amino nitrogen content, alkalinity coefficient, molasses sugar, white sugar content, extraction coefficient of suga...

Plasma colloid osmotic pressure (COP) is an important determinant in edema formation. Three methods for assessing the COP were evaluated. Direct measurement of COP using the 4420 Wescor Colloid Osmometer was compared to the estimation of COP from both serum total protein and total serum solids (TSS) determinations. Blood samples from twenty adult patients (mean age = 64 years) undergoing card...

Background: The tan spot disease of wheat caused by Pyrenophera tritici-repentis has become a major disease in most wheat growing areas worldwide. Objectives: Here we used ISSR and RAPD markers to study the genetic diversity of 34 P. tritici-repentis isolates collected from North of Iran. Materials and Methods: The leaves having the typical symptoms of tan spot disease were collected and after...

In recent years, excessive use of chemical fertilizers and lack of organic fertilizers caused to reduce the rate of soil organic matter in Iran. The increased use of chemical fertilizers in agriculture causes environmental problems such as soil physical degradation and soil nutrient imbalances. This study was conducted to investigate the effects of foliar and soil applications of humic acid on ...

Date palm (Phoenix dactylifera L.) is a monocot, dioecious and high longevity tropical plant greatly considered due to its high economic importance in Middle East. This investigation was carried out to detect genetic relations among 34 cultivars of Iranian date palm, both males and females, using ISSR markers. Accordingly, total DNA was extracted using CTAB method and was subjected to PCR ampli...

relative resistance of 43 iranian as well as introduced apple cultivars to blue mold (penicillium expansum) was studied within years 2010-2011. the fruit physicochemical traits were also evaluated as measures of potential resistance to decay. local p. expansum strains were isolated from decayed apple fruits and the most aggressive isolate (5,000 spores ml-1) used as inoculum. fruits were wound-...

Physicochemical properties of banana peel flour (BPF) were studied in two varieties (Cavendish and Dream) and two stages of ripeness (green and ripe). BPF’s were analyzed for pH, total soluble solids (TSS), water holding capacity (WHC) at 40, 60 and 80C, oil holding capacity (OHC) at 40, 60 and 80C, colour values L, a and b, back extrusion force and viscosity, and the data were analyzed using...
