چکیده مقاله :

این آزمایش طی دو سال زراعی 89-1388 و 90-1389 در مرکز تحقیقات کشاورزی و منابع طبیعی استان اردبیل (مغان) با استفاده از 17 ژنوتیپ سویا و در قالب طرح بلوک‌های کامل تصادفی در سه تکرار به منظور ارزیابی کارایی مصرف نور در ژنوتیپ‎های سویا اجرا شد. بر اساس نتایج تجزیه واریانس مرکب، تاثیر سال بر تعداد غلاف و دانه در بوته سویا معنی‌دار بود. کلیه صفات مورد بررسی در میان ژنوتیپ‌ها تفاوت معنی‌داری در دو سال داشتند. بیشترین و کمترین ضریب استهلاک نوری در ژنوتیپ‌های Hsus-H116 (084/0 ± 62/0) و Apollo (031/0 ± 44/0) مشاهده شد. بالاترین و پایین ترین کارایی مصرف نور نیز در ژنوتیپ‌های Darby (134/0 ± 14/1) و L.17 (152/0 ± 91/0) مشاهده شد. ژنوتیپ‌های Zane و Apollo به ترتیب بیشترین تعداد غلاف و دانه در بوته را در هر دو سال داشتند. بالاترین وزن صد دانه در سال اول از ژنوتیپ Omaha و در سال دوم از NE-3399 به دست آمد. بالاترین عملکرد دانه در سال اول، از ژنوتیپ‌ Apollo (3513 کیلوگرم در هکتار) و در سال دوم از ژنوتیپ Zane (3774 کیلوگرم در هکتار) به دست آمد در حالی‌که ژنوتیپ‌های Rend و L.83-570 کمترین عملکرد دانه را در هر دو سال داشتند.

چکیده انگلیسی:

This experiment was carried out for two years (2009-2010) with using 17 soybean genotypes at Agriculture and Natural Resources Research Centre of Ardabil (Moghan) as a completely randomized block design with three replications. Eco-physiological and agronomic parameters such as extinction coefficient, light use efficiency, yield and yield components was investigated in soybean at second cropping. Based on analysis of combined variance, the effect of year was significant on number of pods and seeds per plant. All traits were differences significant among genotypes in both years. The maximum (0.62 ± .084) and minimum (0.44 ± 0.034) values for light extinction coefficients were obtained from Hsus-H116 and Apollo genotypes respectively. The highest radiation use efficiency (1.14 ± 0.134) was obtained from Darby, and the lowest (0.91 ± 0.152) from L.17 genotype. Apollo and Zane genotypes had the highest number of pods and seeds per plant in both years. The highest seed weight was obtained from Omaha and NE-3399 genotypes in first and second years, respectively. The highest seed yield was obtained from Apollo (with 3513 Kg. ha-1) in first year and from Zane genotype (with 3774 Kg. ha-1) at second year of experiment, whereas Rend and L.83-570 genotypes had the lowest seed yield in both years.
