The effect of dehydration on the specific activities and transcript levels of several glycolytic enzymes was determined in two chickpea (Cicer arietinum L.) cultivarsPusa362 (drought tolerant) and SBD377 (drought sensitive). Dehydration treatment was imposed on 6 days old chickpea seedlings by removing them from pots and keeping them on table top on 3MM Whatman paper at room temperature for 5 h...
Water shortage seriously threatens crop growth and development especially in semi-arid areas. Association of plants with beneficial soil microorganisms is a strategy for plant adaptation to environmental stresses. In this study, the effect of seed inoculation of rapeseed genotypes with mycorrhiza-like fungus (Piriformospora indica) and growth-promoting bacterium (Arthrobacter siccitolerans) was...
Changes in freezing injury percentage, lipid peroxidation (malonaldehyde formation), antioxidant enzymes activity and proline content were monitored in the leaves of olive cvs. ‘Fishomi’ and ‘Roughani’ under diff erent freezing temperatures (-5, -10, -15 and -20°C for 10 h). Th e results showed that freezing injury (determined by electrolyte leakage analysis) and malonaldehyde (MDA) content of ...
in this study, effect of different concentration of ascorbic acid (asa, 0, 2, 4 and 6 mm) on delaying senescence in cut rose flowers cv. royall class was investigated based on factorial design. the results showed that the greatest delay in senescence was obtained with 4 mm asa as compared to control (distilled water). therefore, fresh weight and diameter of flowers treated with 4 mm asa was mor...
This study was conducted to evaluate the effect of drought stress on 22 durum wheat genotypes. Different characteristics such as grain weight per spike, plant biomass, 100 grain weight, free proline content in leaves, and percentage of cell membrane damage were studied in greenhouse and laboratory conditions. Genotypes were sown under normal irrigation and moisture stress conditions. In stres...
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 ...
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...
In order to assess the effect of drought stress and various levels of potassium on solutes accumulation and chlorophyll of canola and Indian mustard, a field experiment was conducted in a factorial design based on randomized complete block design with three replications including three irrigation regimes (I1=irrigation after 50% depletion of soil water(control),I2 =irrigation after 70% water de...
A Thlaspi caerulescens (J. & C. PRESL) was used to study the effect of cadmium on the content of free amino acids and ability accumulation of Cd in ecotypes of this plant species. In pot experiment two ecotypes T. caerulescens were used: Ganges ecotype from France and Mežica ecotype from Slovenia. The plants were grown in soil (chernozem – Suchdol) spiked with NPK and three different concentrat...
