Assessing genetic diversity of promising wheat (Triticum aestivum L.) lines using microsatellite markers linked with salinity tolerance
Narrow genetic variability may lead to genetic vulnerability of field crops against biotic and abiotic stresses which can cause yield reduction. In this study a set of 37 wheat microsatellite markers linked with identified QTLs for salinity tolerance were used for the assessment of genetic diversity for salinity in 30 promising lines of hexaploid bread wheat (Triticum aestivum L.). A total of 4...
متن کاملEffect of Water Deficit Stress on Physiological Characteristics in Wheat (Triticum aestivum L.)
Abstract Terminal drought stress is one of the most important environmental stresses affecting plant morphology and physiology and has major effects on agricultural production. The purpose of this experiment was to investigate the effect of water deficit stress on changes in physiological traits of wheat in a randomized complete block design with three replications in two cultivation years of ...
متن کاملImpact of Biotic and Abiotic Stresses on the Competitive Ability of Multiple Herbicide Resistant Wild Oat (Avena fatua)
Ecological theory predicts that fitness costs of herbicide resistance should lead to the reduced relative abundance of resistant populations upon the cessation of herbicide use. This greenhouse research investigated the potential fitness costs of two multiple herbicide resistant (MHR) wild oat (Avena fatua) populations, an economically important weed that affects cereal and pulse crop productio...
متن کاملWheat (Triticum aestivum L.) Growth and Yield as Influenced by Flooding and Salinity Stresses in Northern Iran
Salinity and flooding are as two very important factors of soil degradation. They often occur together and cancause severe damage to plants. However, plant response to environmental stresses may vary with growth stage atwhich exposure occurs. A pot study was conducted in 2005-2006 in northern Aq Qala (northern Iran) to studycombine effects of waterlogging and soil salinity at different growth s...
متن کاملInfluence of salicylic acid pre-treatment on emergence and early seedling growth of cucumber (Cucumis sativus)under salt stress
Salicylic acid (SA) is a common, plant-produced signal molecule that is responsible for inducing tolerance to a number of biotic and abiotic stresses. An experiment was therefore conducted to test whether the application of SA at various concentrations (0, 0.25, 0.50 or 1.0 mM) through a seed-soaking method would protect cucumber (Cucumis sativus L.) seedlings subjected to salt stress. Aft...
