به منظور مطالعه و ارزیابی شاخصهای تنش خشکی بر عملکرد و اجزای عملکرد دانه، روغن، درصد روغن دانه و کارآیی مصرف آب دانه کنجد، آزمایشی به صـورت کرتهای یکبار خرد شده در قالب بلـوکهای کامل تصادفی با سه تکــرار در سال زراعی 98-1397 در ایستگاه تحقیقات کشاورزی بهبهان اجرا گردید. فاکتور اصلی، مقدار آب در آبیاری قطرهای نواری در چهار سطح 40، 60، 80 و 100 درصد نیاز آبی از شروع مرحله گلدهی و فاکتور فرعی...
to assess moisture stress tolerance at the reproductive growth stage in 11 promising genotypes of spring rapeseed (brassica napus l.), two field experiments were conducted in two growing seasons (2008-2010) at the agricultural research center of safiabad, dezful, iran. genotypes were sown under two non-stress (well-irrigated) and moisture stress (irrigation ceased at flowering) conditions using...
a two years (2006–2007 and 2007-2008) experiment was conducted at national salinity research center, yazd, to evaluate salt-tolerant genotypes of brassica napus, b. rapa and b. juncea. to screen genotypes in the first growing season, 58 genotypes were grown under two irrigation water salinity levels of 2 and 12 ds m-1 in an augmented randomized complete block design with six replicated checks. ...
1 Wheat Research Center, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh ABSTRACT. Twenty five spring wheat genotypes were evaluated for terminal heat stress tolerance in field environments in the Agro Ecological Zone-11 of Bangladesh, during 2009-2010 cropping season. The experiments were conducted at Wheat Research Centre, Bangladesh Agricultural Research Institute, using rand...
heat stress is a major environmental stress limiting wheat productivity in most cereal growing areas of the world. in order to map and characterize quantitative trait loci controlling heat tolerance, 144 recombinant inbred lines deriving from the cross of kauz and mtrwa116 were assessed in a greenhouse and growth chamber at 35°c. one hundred and sixty six ssr and 3 aflp markers were used to...
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...
this study was conducted to evaluate the effect of drought stress on 22 durum wheat genotypes. different characteristics such as grain weight per spike, plant biomass, 100 grain weight, free proline content in leaves, and percentage of cell membrane damage were studied in greenhouse and laboratory conditions. genotypes were sown under normal irrigation and moisture stress conditions. in stress ...
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...
