pomegranate (punica granatum l.) is an important iranian-native fruit, whose many varieties are cultivated. fruits are widely consumed fresh and in processed forms as juice, jams and etc. pomegranate peel, as a by-product of the commercial juice industry, is a rich source of bioactive compounds. this research has been done to evaluate and compare physical characteristics, total phenolics, total...
Climate change has caused major changes in abiotic factors, with water stress as the greatest threat to agricultural production. The measures aimed at alleviating problems by this limiting production factor have occurred through adoption of sustainable strategies, especially microbial biotechnology, which uses interactions between microorganism and plant, ensuring productive quality inducing pl...
Enhanced nitrogen use efficiency (NUE) in turfgrass systems comprises several factors, including more efficient uptake and assimilation of applied (N), as well reduced N losses to the environment. The objectives current research were evaluate inter- intraspecific variation parameters two Agrostis species, creeping bentgrass (Agrostis stolonifera L.) velvet canina L.), under field controlled env...
In order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the College of Agriculture, Shiraz University, Shiraz, Iran during 2010 and 2011 growing seasons. Two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...
gerbera one of 10 important cut flowers in the world and iran. one of the most problems is low-life after harvest and neck bending. producers want to increase longevity of these flowers with using chemical solutions. with the aim of achieving the best chemical treatments to increase flower vase life gerbera goodtimming, nano silver (5 mg l-1), humic acid (50 mg l-1), gibberellic acid (2.5 mg l-...
poinsettia (euphorbia pulcherrima) is a potted plant, which its colorful bracts appear in short days. in thisexperiment, effect of different ammonium to total nitrogen ratios on quantitative and qualitative traits ofpoinsettia was studied. the experiment was conducted as a complete randomized design with threereplicates. the plants were irrigated with water containing of different ammonium to t...
Abstract In calcareous and saline soils, the adverse effect of some ions such as bicarbonate, boron, magnesium, and especially sodium, and the imbalance of nutrients’ concentrations are essential factors which reduce plant growth. A greenhouse experiment was conducted to study the effect of sodium (Na) and magnesium (Mg) on some growth traits and chlorophyll content of pistachio seedlings (cv....
The experiment was performed to study the seed germination and seedling growth in wheat under the influence of different concentrations of copper. The germination %, plumule and radicle length, and number of lateral roots decreased with increase in copper concentration (5, 25, 50 and 100 mgl(-1)). Total chlorophyll contents declined on 14th day from 1.605 of control to 1.581, 1.242, 1.275 and 1...
The effects of 4 different levels of nitrogen (0,120,150, and 180 kg nitrogen per hectare) and one level of poultry manure (10 tons per hectare) on the quantitative and qualitative characteristics of an autumn grown cultivar of cucumber [Cucumis sativus, cv.'super dominos] were studied in DarrehShahr, Ilam. The experiment was conducted in a completely randomized block design with 3 replications...
