Low quality of irrigation water along with increasing salinity level has reduced the olive yield over recent years in Iran. Screening of salinity tolerance in olive cultivars using gas-exchange parameters, water use efficiency, and relative leaf chlorophyll content are important in olive development programs. This study was carried out to assess the salinity tolerance of four olive cultivars (A...
Salt stress is one the major environmental stresses limiting quantitative and qualitative aspects of plant growth. One of the methods to overcoming the adverse effects of salinity is application of growth regulators. Salicylic acid is a plant growth regulator its positive effects in alleviating the adverse effects of stresses on plants have been reported. In order to study the effect of salicyl...
this experiment was conducted using 216 male chicken (ross 308) to evaluate the effects of organic selenium and sodium bicarbonate supplementation on blood parameters, growth performance and carcass characteristics in heat stress condition. birds were reared under same condition and fed with similar diets till 28 d of age. at 28 days of old, broiler with similar weight were regrouped within die...
cyphomandra betacea (cav.) is a native species from south america that is cultivated because its fruits have a high content of vitamins. in colombia, it is common to find periods of drought between the rainy seasons or during enso events such as el niño. an adequate nutritional status of k+ in plants helps to increase the chance of tolerating the negative effects of drought stress. regarding th...
Plant used different mechanisms to avoidance drought stress. This study was conducted to evaluate the role of exogenous application of glycine betaine in improving drought tolerance of Brassica napus. The study was performed on randomized complete block design with 3 replications. Different amounts of glycine betaine i.e. 0, 100 and 200 mM in combination with various irrigation periods i.e. 3, ...
The management of soil elements by biological fertilizers is considered as an important attribute of sustainable agriculture. In order to evaluate the interaction effects of Arbuscular mycorrhizal fungi and redroot pigweed (Amaranthus retroflexus L.) on growth and yield of sunflower (Helianthus annuus L.) under water stress conditions, a field study was conducted in 2015 at School of Agricultur...
in order to evaluate the effects of drought and salinity stresses on growth parameters and essential oil of lemon balm, two experiments with three replications in a randomized complete block design were applied. five levels of salinity including zero, one, two, three and four ds/m of sodium chloride solution, and five drought stress treatments including 50, 62.5, 75, 87.5 and 100% as available ...
in order to evaluate the effects of biofertilizer on soybean (glycine max l.) seed vigor that produced under water deficit condition and related traits, an experiment was conducted in a factorial layout based of complete randomized block design with four replications at the research greenhouse of aboureihan campus- tehran university, iran. experimental treatments were include biofertilizer (see...
introduction safflower is native to iran, and is cultivated for high adaptability, low water requirement, resistance to drought and useful unsaturated fatty acid (ashri et al., 1977). identification of effective agronomic traits and relationship between them are important aims under water stress conditions. among these characters, grain yield is the most important trait that is genetically poly...
drought and salinity are the most important limiting factors of plant growth and development in many regions of the world. in this regard, using of species that are able to have higher production in this condition is a suitable strategy. in order to study the effect of drought and salinity stresses on morphophysiological properties of kallar grass (leptochloa fusca l. kunth), a factorial experi...
