| چکیده | ||
| این تحقیق به‌منظور بررسی اثر فرآیند پس از یرداشت بر کیفیت بذر 2 رقم تجاری سویا ویلیامز و صبا(L17) در منطقه مغان به صورت یک آزمایش عاملی 5×2، دو رقم×5 مرحله فرآیند پس از برداشت، شامل پس از برداشت، پس از خشک‌کردن، پس از بوجاری، پس از بسته‌بندی و پارت چینی و انبارداری، برپایه طرح کاملاً تصادفی با 3 تکرار انجام شد. صفات مورد بررسی درصد گیاهچه‌های عادی در آزمون جوانه‌زنی استاندارد و پس از آزمون پیری تسریع شده، شاخص وزنی بنیه گیاهچه پس از آزمون جوانه‌زنی استاندارد، درصد بذرهای شکسته، درصد بذرهای با پوسته ترک‌خورده و هدایت الکتریکی بودند. نتـایج نشان داد رقم ویلیامز از درصد گیاهچه‌های عادی پس از آزمون پیری تسریع شده و شاخص وزنی بنیه گیاهچه پس از آزمون جوانه‌زنی استاندارد بیشتر و درصد بذرهای با پوسته ترک‌خورده کمتری برخوردار بود. همچنین کمترین درصد گیاهچه‌های عادی در آزمون جوانه‌زنی استاندارد، درصد گیاهچه‌های عادی پس از آزمون پیری تسریع شده و شاخص وزنی بنیه گیاهچه پس از آزمون جوانه‌زنی استاندارد و بیشترین درصد بذرهای شکسته، درصد بذرهای با پوسته ترک خورده و هدایت الکترکی پس از مراحل خشک‌کردن و انبارداری مشاهده شدند. براساس نتایج این تحقیق بذرهای رقم ویلیامز از توانائی حفظ قابلیت جوانه‌زنی و بنیه بیشتری در خلال مراحل فرآیند پس از برداشت نسبت به رقم صبا(L17) برخوردار بود. همچنین کاهش قابلیت جوانه‌زنی و بنیه بذر پس از مراحل خشک‌کردن و انبارداری نامناسب بودن فرآیند خشک‌کردن بذرها را مشخص کرد. | ||

| چکیده [English] | ||
| This research in order to study on post-harvest process effect on 2 soybean commercial Williams and Saba (L17) in Moghan region was conducted as a 2×5, two cultivars× 5 post-harvest process stages including after harvest, after drying, after cleaning after packing and stacking and storage, factorial experiment based on completely randomized design by 3 replications. Studied traits were normal seedlings percent in standard germination test and after accelerated ageing test, seedling weight vigour index after standard germination test, broken seeds percent, cracked coat seeds percent and electrical conductivity. Results revealed Williams cultivar had more normal seedlings percent after accelerated ageing test and seedling weight vigour index after standard germination test and less cracked coat seeds percent. Also the least normal seedlings percent in standard germination test, normal seedlings percent after accelerated ageing test and seedling weight vigour index after standard germination test and the most broken seeds percent, cracked coat seeds percent and electrical conductivity investigated. Based on this research results Williams cultivar seeds had more germination ability and vigour preservation potential during post-harvest process stages than Saba (L17) cultivar. Also germination ability and vigour decrease after drying and storage stages revealed seed drying unsuitability. | ||
