A hydroponic experiment was carried out to compare root anatomy and hydraulic conductivity of four barley cultivars including Valfajr, Karoon, Afzal and Zarjo under salt stress conditions. The results showed that under salt stress, the minimum diameter of vessels was observed in the peripheral metaxylem of seminal roots of Valfajr cultivar and in adventitious roots; Karoon with 19±3 µm had maxi...

chamran 2 cultivar with the pedigree attila 50y//attila/bacanora, originated from national cereal breeding program by crossing between chamran cultivar and  attila line in karaj (1996-97). the f1 plants were evaluated and selected in 1997-98 cropping season. the new cultivar was evaluated in six warm and dry southern research stations of the country (2004-2006). chamran cultivar with good adapt...

this study was carried out to investigation the possibility of using triadimefon (trd) in order to decrease the adverse effects of salt stress on medicago plant. triadimefon is a member of triazol compounds which enhances stress tolerance through physiological processes. two cultivars of medicago sitiva including hamedani and yazdi were used in this study. plants were treated with 1, 2 and 4 mg...

Large portions of the Great Plains and the western U.S. are regularly plagued by drought and diminishing water resources for irrigation. Alfalfa cultivars adapted to these regions, and that can remain productive under reduced irrigation allotments, are clearly needed. This study evaluated the potential of using DNA marker assisted selection (MAS) technology to improve alfalfa forage productivit...

a hydroponic experiment was carried out to compare root anatomy and hydraulic conductivity of four barley cultivars including valfajr, karoon, afzal and zarjo under salt stress conditions. the results showed that under salt stress, the minimum diameter of vessels was observed in the peripheral metaxylem of seminal roots of valfajr cultivar and in adventitious roots; karoon with 19±3 µm had maxi...

Cold stress is the main factor limiting rice production and distribution. Chaling wild can survive in cold winters. AP2/EREBP a known transcription family associated with abiotic stress. We identified members of rice, maize, Arabidopsis, conducted collinearity analysis gene analysis. used Affymetrix array technology to analyze expression genes cultivated cultivar Pei’ai64S, which sensitive cold...

A series of controlled-environment experiments were conducted to elucidate the effects of Meloidogyne incognita on host physiology and plant-water relations of two cotton (Gossypium hirsutum) cultivars that differed in their susceptibility to nematode infection. Inoculation of M. incognita-resistant cultivar Auburn 634 did not affect growth, stomatal resistance, or components of plant-water pot...

Phytohormones such as auxin are known to be involved in alleviating the detrimental effects of salinity by modulating the activity of enzymatic antioxidants and improving antioxidant system, which help in sustaining plant growth. The present study envisaged revealing the role of exogenous application of indole-3-acetic acid (IAA) in improving defense mechanisms in two genotypes (FL485 and IR29,...

Drought stress severely affects growth, development and productivity in most agricultural crops. Since ancient times, rootstocks have been used to enable crop cultivation unsuitable soil conditions. In the present study, three factors were evaluated: 1) cultivar: Vitis vinifera L. cv. ‘Horozkarası’ (drought-tolerant) ‘Kabarcık’ (drought-sensitive) used; 2) rootstock: each cultivar was self-root...
