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 ...
Drought stress is one of the most important factors limiting plant growth all around the world. Plant Growth Promoting Rhizobacteria (PGPR) can significantly reduce drought stress effects on plants growth. This study was aimed to investigate the influence of PGPR (inoculation by Azospirillum lipoferum, Azotobacter chroococcum, Pseudomonas aeruginosa, and Bacillus cereus) on seed germination, se...
Drought is the most important problems that restrict cultivation of horticultural crops in arid and semi-arid regions and olive (Olea europaea L.) as an important fruit trees grows in these regions. In order to investigate the effect of cycocel treatment on some physioligical characteristics of two olive cultivars (Mary and Mission), under the condition of drought stress, a greenhouse experimen...
Drought stress reduces the yield and production of tomato (Lycopersicum esculentum Mill.). Tomato does not naturally accumulate glycinebetaine (GB) in the cells under natural conditions. Effects of exogenous glycinebetaine on some morpho-physiological characteristics of Lycopersicum esculentum Mill. cv. PS was evaluated at different levels of drought stress. The experiment was conducted in a fa...
to study the effect of aquazorb super absorbent polymer (sap) on reducing drought stress of acacia victoriae seedling, a split plot experiment based on the completely randomized design was conducted. in this research, stressed treatment as the main plots and amount of superabsorbent were considered as sub plot. treatments were applied consisted of four levels of drought stress (15, 30, 60 and 1...
Water stress is a global crisis and is considered a serious threat for agriculture. Superabsorbent polymers, through improving soil physical conditions, prevent moisture stress in arid and semi-arid areas. To evaluate the effects of a natural superabsorbent (bentonite) and a synthetic superabsorbent (A200) on growth of lettuce, a factorial experiment in a completely randomized design with four ...
In order to investigate the effect of drought stress by application of hormone and nanoparticulate spraying on corn biochemical traits, a split factorial was used in a randomized complete block design with four replications at the Agricultural Research Faculty of Islamic Azad University, Varamin. Drought stress in two levels (drought stress and drought stress) and three growth regulators (appli...
salinity and drought stress are among the common environmental factors which adversely affect germination and growth of plants. this experiment was conducted to evaluate the effects of salinity and drought stress on turnip seed germination and early growth in seed lab of college of agriculture, university of tehran, during 2010. the experimental design was a complete randomized block with three...
this thesis attempts to measure learning styles, self efficacy and intrinsic motivation as predictors of iranian ielts reading comprehension. in order to address this issue, a quantitative study was conducted on some randomly selected intact students at ferdowsi university. these two groups were assigned as they were undergraduate (ba=91) and graduate (ma =74) students; they were all aged betwe...
in order to evaluate the effects of foliar application of methanol on some physiological characteristics of chickpea under drought stress, an experiment was conducted as a factorial based on completely randomized design with three replications in 2011 at the recearch center of plant for sciences in ferdowsi university of mashhad. the first factor was different levels of methanol including, 0 (c...
