drought is considered as one of the most important limiting factors for oil seed canola plant(brassica napus l.) growth and productivity in iran. on the basis of root and shoot dry weight asaffected by water stress exerted by peg 6000, out of 9 canola cultivars, a relatively tolerant (cv. aghaii)and a sensitive cultivar (cv. po4) were selected. their responses to low water potential with respec...

In order to investigate the effects of salt stress on biochemical and physiological responses of two cultivars of alfalfa (Medicago sativa L.) namely, Diabolourde and Yazdi, chlorophyll content, growth parameters, and proline contents of roots and shoots, reducing sugars contents of roots and shoots, and membrane injuries of the plant samples were subjected to 0, 100, 150, and 200 mM NaCl treat...

Drought and salinity are the major environmental factors that affect rice productivity. Comparative transcriptome analysis between tolerant and sensitive rice cultivars can provide insights into the regulatory mechanisms involved in these stress responses. In this study, the comparison of transcriptomes of a drought-tolerant [Nagina 22 (N22)] and a salinity-tolerant (Pokkali) rice cultivar with...

This study was conducted on two canola (Brassica napus) cultivars, Okapi a winter type and cold tolerant and Rgs003 a spring type and cold sensitive. Seedlings were grown in an environmentally controlled growth room with 16 h d-1 photoperiod at 22/16 °C (day/night, control). At the 4-leaf stage, half of pots were transferred to a cold growth room for 7 d at 10/3°C (day/night, cold treatment) an...

A factorial experiment with forty one triticale genotypes and two wheat cultivars (‘Kavir’ bread wheat cultivar and ‘Dipper-6’ durum wheat cultivar as salt-tolerant genotypes) as the first factor and six salinity levels of 0, 0.5, 1, 1.5, 2 and 2.5 percent (0, 85, 170, 255, 340 and 425 mM) of NaCl as the second factor was conducted. Results indicated that the increase of salinity level has lead...

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...

This research was carried out to determine effect of sorghum cultivars and copper foliar spray on physiological traits under saline water situation via split plot experiment based on randomized complete blocks design with four replications during 2015 and 2016 year. The main plot consisted sorghum cultivars at three level (Kimia, KGS10, KGS4) and Copper foliar spray (C1: 0 or control...

St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] is the least cold-hardy turfgrass species. Development of freezing-tolerant St. Augustinegrass cultivars would greatly benefit home owners in many southern states of the US. Towards this breeding goal, 7800 plants regenerated through tissue culture and 36 germplasm accessions were screened for improved freezing tolerance. Among the con...
