Relative water content may be accurately estimated using the ratio of tissue fresh weight to tissue turgid weight, termed here relative tissue weight. That relative water content and relative tissue weight are linearly related is demonstrated algebraically. The mean value of r(2) for grapevine (Vitis vinifera L. cv. Shiraz) leaf tissue over eight separate sampling occasions was 0.993. Similarly...
The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...
physiological changes of wheat plants which seed pretreated by salicylic acid under late sowing date
wheat, cv. alvand, under late sowing condition and comparison with conventional sowing date was investigated in a field experiment in 2009-2010. the factors were seven levels of priming by sa, including control or untreated seeds, 400, 800, 1200, 1600, 2000 and 2400 µm sa and two sowing dates including conventional sowing date (23 october) and late sowing (22 november). results showed that prim...
Soil salinity is one of the important and determinant factors in land degradation and desertification. This study was undertaken to investigate salt tolerance in Salsola tomentosa under greenhouse conditions to choose a suitable species for saline conditions. The treatment solutions for salinity tests were different concentrations of NaCl (0, 100, 200, 300, 400, and 500 mM) with three replicate...
Drought Stress is one of the most important limiting factors in plants growth and development. Growth regulator, Trinexapac-ethyl, might improve drought stress resistance via reducing stem growth and improving osmotic adjustments. In present study Trinexapac-ethyl effect on some tall fescue var Rebel physiological and morphological traits under irrigation free conditions was studied. So, an exp...
This experiment was conducted in 2010 in order to study the effect of drought stress on proline, soluble carbohydrates, relative water content, concentration of potassium and sodium of leaf, electrolytes leakage from leaves and grain yield of spring rapeseed cultivars in Research Greenhouse of Yasouj University, Yasouj, Iran. The experiment was factorial, based on completely randomized design w...
evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...
drought stress is one of the most important problems of agriculture and an important factor of plant product reduction. application of absorbent materials can help usage of sporadic rain fall and cause more maintenance of water storage. in order to study the effect of super absorbent polymer, potassium sulfate and manure under drought condition and favorable irrigation on some traits of foxtail...
Drought is one of the most important environmental stresses that adversely affect plant growth and crop production will In order to study a factorial randomized complete block design with three replications in greenhouse Ardabil University mohaghegh was conducted in 2013. Treatments were water stress at three levels: 35%, 55% and 75% field capacity and seed inoculated with mycorrhiza growth pro...
this study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (triticum aestivum l.) cultivars (azar2, darab2, shiraz, and falat) inoculated with the fungus glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the school of agriculture, shir...
