Bound Water in Durum Wheat under Drought Stress.
To study drought stress effects on bound water, adsorption isotherms and pressure-volume curves were constructed for two durum wheat (Triticum durum Desf.) cultivars: Capeiti 8 (drought tolerant) and Creso (drought sensitive). Plants were grown under well-watered and water-stressed conditions in a controlled environment. Differential enthalpy (DeltaH) was calculated through van't Hoff analysis ...
متن کاملVascular Architecture Alterations in Expanding Durum Wheat Leaf Under Salinity
The leaf growth and cross-sectional area of durum wheat during its development may be reduced under salt stress due to vascular architecture alterations of leaves. A hydroponic experiment was conducted to compare growth rate and vascular architecture changes of two durum wheat cultivars including Shabrang and Yavaroos under 0 and 100 mM NaCl. Plants were sampled at the three-leaf stage growth. ...
متن کاملRelationship between leaf stages and epistasis for resistance to Stagonospora nodorum in durum wheat
Ten varieties and eight generations (2F1, 2F2, 2B1 and 2B2) of durum wheat derived from two crosses were evaluated for resistance to natural infection by Stagonospora nodorum blotch (SNB) at the 2-3 and 6-7 leaf stages at two sites over two years. There were significant differences in the incidence of SNB between leaf stages in most of the wheat varieties, with resistance being most evident at ...
متن کاملSome Physiological and Biochemical Effects of NaCl Salinity on Durum Wheat (Triticum durum Desf.)
The main objective of this study was to examine the effects of NaCl on the leaf growth and some physiological and biochemical characteristics of an Algerian durum wheat (var. Waha) landrace. NaCl (150 mM), as compared to control plants, significantly reduced all the leaf-growth parameters as leaf area (33%), leaf dry weight (41%) and leaf fresh weight (32%), but did not induce any change in the...
متن کاملSystems Responses to Progressive Water Stress in Durum Wheat
Durum wheat is susceptible to terminal drought which can greatly decrease grain yield. Breeding to improve crop yield is hampered by inadequate knowledge of how the physiological and metabolic changes caused by drought are related to gene expression. To gain better insight into mechanisms defining resistance to water stress we studied the physiological and transcriptome responses of three durum...
