An increased awareness of environmental protection and sustainable production raise the necessity incorporating selection low nitrogen-tolerant winter wheat cultivars for high yield quality in breeding process. This can be assisted by using stress screening indices. Our study aimed to evaluate compare a number indices determine select most nitrogen deficiency-tolerant further breeding. The expe...
For evaluation of the traits related to water deficit stress in 20 spring wheat (Triticum aestivum L.) cultivars and subsequently determination of the most tolerant and sensitive cultivars, an experiment was carried out in split plot based on randomized complete block design (RCBD) in the research farm of the University of Tabriz, Iran during 2010-2011 and 2011-2012 crop seasons. The first fac...
Powdery mildew (PM - Eryshpe necator) is one of the most important diseases threatening world viticulture. This study determined that gene expression levels Myc2, WRKY1, and DHN1a in Boğazkere (V. vinifera L. PM susceptible), Cabernet Sauvignon Kishmish Vatkana tolerant), Regent tolerant) cultivars after PM-Methyl jasmonate (MeJa) treatments by real-time polymerase chain reaction (RT-PCR). The ...
terminal drought stress during grain filling period has recently become more common in the semiarid mediterranean regions, where wheat (triticum aestivum) is grown as an important winter cereal crop. the objective of this experiment was to study the effect of terminal drought stress on grain yield, gas exchange variables, and some physiological traits of nine bread wheat cultivars. an experimen...
This research was conducted to evaluate 30 sainfoin cultivars in terms of yield, agronomic and morphological traits under water stress condition, using different drought tolerannce indices. A randomized complete block design with three replications was employed during two years at Isfahan University of Technology Research Farm, Isfahan, Iran. Effect of cultivars were significant for all of the ...
In order to study the tolerance mechanism of spring bread cultivars to wild oat competition, an experiment was conducted in research farm of Ramin Agricultural and Natural Resources University of Khouzestan as strip block with three replications during 2010-2011 growing season. Experimental factors were wild oat densities includ 0 (as control) and 80 plant/m2 as horizontal plots and ten wheat c...
Drought is the most significant constraint for crop production in arid and semi-arid regions. In order to assess drought tolerance in fifteen rapeseed (Brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of College of Agriculture, Shiraz University, Shiraz, Iran during 2009-2010 growing season. The cultivars were...
Plants are usually exposed to a range of environmental stresses. These stresses have undesirable effects on survival create growth, quantity and quality of agriculture products. Chilling stress is one of them that can damage cereals at the reproductive stage. The aim of present study was investigation of chilling effects on physiological traits, plant pigments (total, a and b chlorophyll and Ca...
Plants have developed multiple regulatory mechanisms to respond and adapt to stress. Drought stress is one of the major constraints to agricultural productivity worldwide and recent reports have highlighted the importance of plant sRNA in the response and adaptation to water availability. In order to increase our understanding of the roles of sRNA in response to water depletion, cultivars of su...
Salt stress strongly affects on plant growth and development, especially maize plant, which is reported as a salt sensitive species. The salt tolerant identification in the large genetic resources and breeding population is a profitable research topic for solving the salinity problem. Two maize cultivars, viz., sweet (Zea mays L. cv. Saccharata) and waxy (Z. mays L. cv. Ceratina) seedlings were...
