Aluminum is one of the most abundant elements in soil that become soluble form as Al+3 in high acidic soils, absorbed through the roots and affect on plants growth. Evaluating plant tolerance to environmental stresses in seedling stage is an important factor for selecting plant to cultivate in different conditions. In order to evaluate tolerance of 83 durum wheat advanced line at aluminum toxic...

Plants of six wheat varieties (Damani, Hashim-8, Gomal-8, DN-73, Zam-04, and Dera-98) were grown under three water regimes i.e. 100% Field Capacity (FC), 35% FC and 25% FC. Results of this experiment showed highly significant difference among wheat varieties in all the studied traits and water stress conditions decreased them significantly. The superior variety Hashim-8 which indicated higher r...

Drought stress is the major problem in arid and semi-arid regions of the world. Investigating the response of different cultivars of crop plants to drought stress can help to select the tolerant ones for agriculture in arid lands. In this study, a greenhouse experiment was conducted as a factorial experiment based on completely randomized design with two common bean cultivars (Phaseolus vulgari...

Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...

Drought is an important factor limiting crop production in arid and semi-arid conditions. Drought indices which provide a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions. Ten barle...

This research was conducted to evaluate drought tolerance of safflower genotypes (Carthamus tinctorius L.) at the research farm of Isfahan University of Technology, Isfahan, Iran during growing season of 2012. One hundred genotypes including 81 foreign genotypes along with 19 Iranian genotypes were evaluated under normal and moisture stress conditions according to a simple lattice design with t...

Common bean is adapted to relatively cool climatic conditions and temperatures of>30 Cduring the day or>20 C at night result in yield reduction. The long-term goal of breeding for heat tolerance is the development of germplasm with improved field level tolerance under variable temperature conditions. Using previously developed stress indices, this studypresents results fromhigh temperature scre...

Drought stress is considered as one of the most important constraints to the crop production, including medicinal plants in many arid and semi-arid regions. This study was carried out to determine the most effective indices for drought tolerance and identification of tolerance genotypes under drought conditions in N. sativa. For this purpose, 36 genotypes of N. sativa were tested as a split plo...
