in order to comparison and determination of the best drought tolerance indices in sweet corn hybrids, an experiment was conducted using a randomized complete block design in split plot lay out with three replications at seed and plant improvement institute in karaj in 2006. three irrigation levels (irrigation after 75 as control, 100 and 125 millimeters cumulative evaporation from class a evapo...
As other crops, oilseed rape (Brassica napus L.) is severely affected under drought conditions. The mechanisms which reduce damages caused by oxidative stress have important roles in resistance of plants to drought stress and antioxidant enzymes have primed importance in this regards. In this factorial experiment 9 oilseed rape genotypes were compared under 3 stress levels (FC, 75%FC, 50%FC) in...
تجزیه ژنتیکی برخی صفات مورفولوژیک در گندم از طریق تجزیه میانگین نسلها در شرایط تنش و عدم تنش رطوبتی
Study of heritability, types of genes action and determination of effective breeding strategy to improve physiological and morphological traits especially under drought stress conditions are very important. For such purpose, an experiment was carried out using the generations of the crosses between two pure lines (Kavir × Roshan) under drought stress and non-stress conditions based on randomiz...
earliness and drought escape are as a primary strategy for plant adaptation in regions that plants are subjected to terminal drought stress. plants react to drought through morphological changes and alteration in physiological behavior. accordingly, two separate experiments to assess the response of yield and morphophysiological characteristics of earliness chickpea genotypes to drought stress ...
In order to evaluate the effect of drought stress and determine of effective traits on grain yield and estimate of genetic parameters, 18 mutant rice lines were studied in normal and drought stress conditions. The experiments were carried out separately using randomized complete block design with three replications during cropping season 2014-2015 at Iranian Rice Research Centers in North of Ir...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
introduction drought stress is one of the most important abiotic stresses all around the world. the aim of breeding studies and breeding for resistance to drought is that breeders seek to identify varieties and genetic resources to drought resistant and comparison of drought resistance among the varieties and the introduction of superior varieties to farmers. drought or imbalance between supply...
in order to evaluate drought tolerance of cultivars and advanced grain sorghum lines, an experiment was conducted as split-plot on randomized complete blocks design with three replications at experimental field of seed and plant improvement institute, karaj in 2009. three levels of irrigation regimes including normal irrigation (ir0=60 mm), moderate stress (ir2=120 mm) and sever stress (ir3=180...
One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...
the responses of yield and yield components of 24 advanced bread wheat genotypes to pre- and post-anthesis drought stress conditions were studied at ardabil agricultural re-search station during the 1997-2000 cropping seasons. results showed that genotypes produced significantly lower spikes no./m2, seeds no./spike and grain yield under pre- than in post-anthesis drought stress conditions. howe...
