effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Canopy position has a profound effect on soybean seed composition
Although soybean seeds appear homogeneous, their composition (protein, oil and mineral concentrations) can vary significantly with the canopy position where they were produced. In studies with 10 cultivars grown over a 3-yr period, we found that seeds produced at the top of the canopy have higher concentrations of protein but less oil and lower concentrations of minerals such as Mg, Fe, and Cu ...
متن کاملRising Atmospheric Carbon Dioxide and Seed Yield of Soybean Genotypes
ally show less seed yield response than vegetative response with a subsequent decline in apparent harvest If intraspecific variation to rising atmospheric CO2 exists in soybean index as CO2 increases (Cure and Acock, 1986; Prior [Glycine max (L.) Merr.], such variation could be used to select for optimal, high-yielding cultivars. To quantify the range and determine and Rogers, 1995). This has b...
متن کاملeffect of canopy temperature on protein and sugar soluble content, oil and yield of soybean in karaj and moghan areas
in order to study the canopy temperature effect on protein and soluble sugar, oil percentage and yield of soybean in different planting dates, an experiment was conducted as factorial based on randomized complete block design with three replications in karaj and moghan areas during 2012-13. the studied treatments were included cultivar (‘williams’ and ‘l17’) and planting date (5th of may, 5th o...
متن کاملRunoff and sediment yield modeling using WEPP in a semi-arid environment (Case study: Orazan Watershed)
Water erosion is a major environmental problem in many parts of the world. Majority of semi-arid countries are concerned because of their specific climate and soils sensitivity, but also because of the recent intensification of human activities and agricultural practices. Accurate estimation of water erosion for various land-use and climate scenarios is so an important key to define sustainable...
