physiological study of wheat varieties under abiotic stress conditions is a very important factor for improving their future productions. this research work was conducted in the research greenhouse of faculty of agriculture, tarbiat modarres university in 2006, to study leaf quantitative traits of durum wheat under different levels of carbon dioxide (400 and 900 ppm), ultraviolet radiation (uv ...

background: plants infection with microorganisms as well as physical factors such as osmotic stresses especially drought stress induced particular secondary metabolite production. objective: plant root and shoot hyoscyamine (hyo) and scopolamine (sco) variations were investigated under three water deficit stress (wds) levels as 30 (w1), 60 (w2) and 90 % (w3) water depletion of field capacity an...

BACKGROUND: Management of water deficit is a great factor to sustainable crop production, especially in arid and semi-arid regions. Vermicompost is an organic compound that is microbial active and rich in nutrients that results from the interaction of earthworms and microorganisms with organic matter decomposition. OBJECTIVES: This research was carried out to ...

some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...

At percent, Zn stress tolerance using novel genetic resources is an important mitigation strategy for plant breeding. In this study, thirty-five durum wheat genotypes with different growth habits were evaluated under normal (non-stress) and Zn deficient stress during the 2014-15 cropping season. A total of ten Zn stress tolerance indices including stress tolerance index (STI), relative zinc-def...

in order to evaluation the effect of zeolite application and selenium spraying on water relations traits and antioxidant enzymes in medicinal pumpkin (cucurbita pepo l.) at water deficit stress conditions, an experiment was conducted in factorial based on randomized complete block design with three replications during 2010 in takestan, iran. the three levels of irrigation factor include normal ...

expansion of oilseeds cultivation plays an important role in provision of the required edible oils for a country's population. iran is one of the origins safflower as a drought and salt tolerant crop, and therefore, it can be counted on as a suitable alternative crop for cultivation in marginal areas. the aims followed in the present research were on evaluation and selection of late season...

water deficit stress is the most important environmental constraint for growth, yield and productivity of crops, including the oil seed crops. this study was aimed at studying the influence of differing irrigation régimes on growth, chlorophyll , proline and some antioxidants content along with grain yield, yield components and oil content of sesame genotypes using a 4-replicate split plot rand...

A moderate water deficit stress (S1) applied 10 days after anthesis was found to induce acclimation to a subsequent more severe drought stress (S2) in Solanum lycopersicum L.. When plants were pretreated with S1, and then subjected to S2, fruit water status remained similar to controls. In contrast, S2 induced a decrease in both parameters of water status and diameter of fruits from non-acclima...

Drought is one of the most important environmental factors limiting the cultivation of ornamental plants in the green space. The effects of spermidine and salicylic acid on hollyhock (Alcea rosea L.)under drought stress were investigated. At first, the plants were sprayed with 3 doses of spermidine and 3 doses of salicylic acid (control, 100, 200 and 400 μM) for three consecut...
