| ارزیابی اثر منطقه تولید، تصفیه و کرک‌گیری بر جوانه‌زنی و بنیه بذر پنبه رقم ساحل استان گلستان، در تحقیقی به‌صورت فاکتوریل بر پایه طرح کاملاً تصادفی با 4 تکرار انجام شد. تیمارها تصفیه وش مناطق غرب و شرق استان با جین 8 و 16 اره، غلتکی و با دست و کرک‌گیری با اسید سولفوریک و عدم کرک‌گیری بودند. با آزمون جوانه‌زنی استاندارد تعداد گیاهچههای عادی، متوسط زمان جوانه‌زنی، طول و وزن خشک گیاهچه تعیین و هدایت الکتریکی بذرها اندازهگیری شد. اثر متقابل منطقه تولید بذر × روش‌های تصفیه × کرک‌گیری بر صفات معنیدار بود. بالاترین و کمترین تعداد گیاهچه عادی به ترتیب مربوط به بذرهای تصفیه شده با جین غلتکی و کرک‌گیری نشده و بذرهای تصفیه شده با جین 16 اره و کرک‌گیری شده شرق استان بودند. همچنین بذرهای شرق استان تصفیه شده با جین 16 اره و کرک‌گیری نشده و بذرهای غرب استان، تصفیه شده با جین غلطکی و کرک‌گیری شده به ترتیب دارای بیشترین و کمترین متوسط زمان جوانه‌زنی بودند. بذرهای کرک‌گیری نشده و شده غرب و شرق استان، تصفیه شده با جین غلطکی و جین 8 و 16 اره، به‌ترتیب بیشترین و کمترین طول گیاهچه را داشتند. بیشترین و کمترین وزن خشک گیاهچه به‌ترتیب به بذرهای شرق استان تصفیه شده با دست و جین غلطکی و کرک‌گیری شده و نشده بذرهای تصفیه شده با جین 8 و 16 اره و کرک‌گیری نشده این منطقه تعلق داشت. بذرهای غرب استان تصفیه شده با جین 8 اره و کرک‌گیری نشده و بذرهای تصفیه شده با دست و کرک‌گیری شده این منطقه به ترتیب دارای بیشترین و کمترین هدایت‌الکتریکی بودند. براساس نتایج، تصفیه رقم ساحل؛ خصوصاً تولید غرب استان، با جین غلتکی توصیه میگردد تا خسارت مکانیکی پوسته بذر و اثر نامطلوب کرک‌گیری با اسید بر جوانه‌زنی و بنیه بذر کاهش یابد. | ||

| چکیده [English] | ||
| Study of production region, ginning and delinting effects on cotton seed germination and vigor, in Sahel variety was conducted as factorial based on completely randomized design by 4 replications. Treatments were included ginning of cottonseed in west and east area of Golestan by hand, roller, 8 and 16 saw gin and also delinting by Solphoric acid and no delinting. By standard germination test, numbers of normal seedlings, mean germination time, seedling length and dry weight were determined and electrical conductivity of seeds was measured. The interaction effect of Seed production region× ginning methods×delinting was significant on studied traits. The highest and lowest of normal seedlings numbers were related to Seeds of east region ginned by roller, no delinted seeds and 16 saw gin, delinted seeds, respectively. East seeds of Golestan which ginned by 16 saw and no delinting and west of Golestan, ginned by roller gin and delinting had the highest and lowest mean germination time, respectively. Delinted and no delinted seeds in east and west of Golestan province and ginned by roller, 8 and 16 saw gin had the highest and lowest of seedling length, repectively. Seeds of east province which ginned by hand, roller gin and delinted and no delinted seeds which ginned by 8 and 16 saw gin had the highest and the lowest seedling dry weight. The lowest and the highest of electro conductivity were related to ginned seeds of west region by 8 saw gin, no delinting and ginned by hand and delinting, respectively. Based on results, Sahel cultivar seed ginning, especially produced in west of province by roller gin could be recommended for reduction of seed coat mechanical injury and destructive effects of delinting by acid on germination and seed vigor. | ||
