تشدید انباشتگی اسیدهای چرب و هیدروپراکسیدهای لیپیدی در طی زوال بذرهای آفتابگردان
Physiological and biochemical changes during sunflower seed deterioration were studied during incubation for 2, 4, 6 and 8 days at 43 °C and a relative humidity of 100%. Parameters such as germination percentage, germination rate, seedling length, seedling vigor and protein decreased whereas electrical conductivity, fatty acids and lipid hydroperoxides increased during seed deterioration. Incre...
متن کاملeffect 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...
Sowing time and irrigation scheduling effects on seed yield and fatty acids profile of sunflower in semi-arid climate
A research was conducted in Southern Italy to study the changes in seed yield, oil content andfatty acids composition, in response to irrigation at different stages of growing season (at sowing,Dry; from sowing to beginning of flowering, S-BF; from visible bud to 75% flowering, VB-FF;from beginning of flowering to seed ripening, BF-M; from sowing to seed ripening, Full), in astandard sunflower ...
متن کاملChanges in Cell Wall Polysaccharides during Sunflower Seed Development
Developing sunflower (Helianthus annuus L.) seeds were analyzed for their fresh and dry weights, water content and wall components viz. low and high molecular weight xyloglucan and pectic polysaccharides. Seeds from two rows (6th and 12th) differing in their final dry weight and position on the capitulum were selected for the investigation. The dry weight of seed from 6th row was 69 mg while th...
متن کاملFatty acids and fat soluble vitamins content of Black Sea round goby (Neogobius melanostomus, Pallas, 1814) during fishing seasons
The aim of the present study was to determine and compare the seasonal changes in the proximate composition, fatty acids profile and fat soluble vitamins content in spring and autumn goby (Neogobius melanostomus) caught from the Bulgarian Black Sea waters. The proximate composition (moisture, protein and total lipid) has been determined according to AOAC (1990). Analysis of fatty acid methyl e...
