In this study, one-year-old seedlings of Paeonia ostii ‘Fengdan’ were used as materials. The method spraying exogenous salicylic acid (SA), calcium chloride (CaCl2) and abscisic (ABA) was used. effects different concentrations SA, CaCl2 ABA on the heat tolerance peony under high temperature stress studied. optimum concentration mechanism SA-, CaCl2- ABA-induced discussed. results showed that 10...
Extended Abstract Introduction and Objective: Various environmental stresses, especially water deficit stress have several and major effects on maize growth and production. Drought is one of the abiotic stresses that due to the great variety of rainfall conditions, it is known from Iran as the most important factor limiting the growth and production of crops. Therefore, the effect of water def...
Hydrogen gas (H2) and carbon monoxide (CO) are involved in plant growth and developmental processes and may induce plant tolerance to several stresses. However, the independent roles and interaction effect of H2 and CO in adventitious root development under drought conditions have still not received the needed research attention. We hypothesize that there exists crosstalk between H2 and CO duri...
Salinity is an important abiotic stress that reduces growth and productivity of different crops. In many agricultural soils cyanobacteria or blue green algae are the prominent inhabitants, where they potentially contribute to improve soil fertility and crop productivity under normal and abiotic stress conditions. Glycinebetaine is an osmoprtectant compound improving plant tolerance to abiotic s...
Drought is one of most important factors in desert ecosystems that affect plant growth. In this study some of drought parameters in Calligonumpolygonoideswere studied under control and irrigated conditions in natural condition. Results showed significant differences in water potential between control and irrigated conditions. Proline content in control with the amounts of 3.1 mg /gfw was signif...
Few studies have investigated the alkali-based salt resistance aspect of plants. Here, we used 2 pumpkin cultivars (‘Cucurbita ficifolia Bouch.’ and ‘Chuandilong’) to study the growth and physiological response mechanisms of pumpkin to different levels of NaHCO3 stress. After second true leaf development, pumpkin seedlings were treated with varying levels of NaHCO3 stress (0, 30, 60 and 90 mmol...
the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
Raspberry leaf blotch emaravirus (RLBV) has become established in many Serbian raspberry orchards as the most prevalent virus of raspberries country. The aim this study was to evaluate impact RLBV on red ?Willamette? variety. A trial conducted four located Western Serbia. Fruits from RLBVinfected and uninfected canes were analyzed for fruit size (fruit length, width, height, shape, weight), sol...
Deficiency of nitrogen may lead to decrease in yield and yield potential of crop plants. An experiment was done under glasshouse conditions in order to investigate nitrogen levels and salicylic acid interaction on some physiologic traits of borage (Borago officinials L.). In this experiment various levels of nitrogen (including; 27.5, 55, 110, 220 and 330 mg/L from ammonium nitrate) and salicyl...
