چکیده

انتخاب ژنوتیپ­های مناسب برای انبارداری می­تواند از هزینه­های هنگفت انبارداری بکاهد. به منظور بررسی تنوع پتانسیل انبارداری ژنوتیپ­های جو آزمایشی به صورت فاکتوریل سه عاملی در قالب طرح کاملا تصادفی و سه تکرار اجرا شد. عامل اول  شامل هشت ژنوتیپ بومی جو به همراه دو رقم، عامل دوم رطوبت بذر در سه سطح 7، 14 و 18 درصد و عامل سوم مدت زمان پیر کردن بذر (سه روز، یک هفته، چهار هفته) بود. نتایج نشان داد با افزایش رطوبت بذر از درصد جوانه­زنی بذرها کاسته شد به طوری که وقتی رطوبت به 18 درصد رسید فقط ژنوتیپ­های 3 و 4 پس از یک هفته پیری جوانه زدند و در طی یک ماه ذخیره­سازی با رطوبت بذر 18 درصد هیچ جوانه­ای مشاهده نشد. در این آزمون بعد از گذشت یک ماه ذخیره­سازی در بذرهای با رطوبت 18%  محتوای کل فنلی و میزان مالون دی آلدهید کاهش یافت و از بین ژنوتیپ­های مورد بررسی ژنوتیپ 8 (72747) طی سه روز انبارداری با رطوبت بذر 18% بیشترین میزان فنل و درصد جوانه­زنی (78/33)  را دارا بود. از بین ژنوتیپ­های مورد مطالعه ژنوتیپ­های 3 و 4 با منشاء چین و 7 و 8 با منشاء ایران برای مقابله با شرایط نامساعد رطوبت و دمای بالای انبار، سطح آنتی­اکسیدانی خود را بالا برده و  از بنیه و درصد جوانه­زنی  بالایی برخوردار بودند.

چکیده [English]

The expensive cost of seed storage could be reducing by using suitable genotypes. In order to evaluate the variety of storage potential of barley genotypes an experiment was conducted factorially with three factors as completely randomized design with three replications. The first factor was included eight genotypes with two native barley cultivars, the second factor was three levels of seed moisture content including 7, 14 and 18 percentage and the third was aging duration (three days, one week and four weeks). The results showed that germination decreased with increasing moisture content so that when moisture reached 18% only genotype 3 and 4 germinated after one week storage with 18% moisture content after four weeks storage there was no germination in this moisture level. Total phenolic content and malondialdehyde decreased after four weeks storage with 18% seed moisture content and the genotypes studied, genotype 72747 (8) had the highest amount of phenol and germination percentage (78.33%) during three days of storage with 18% seed moisture.The genotypes 3, 4 from China 7 and 8 from Iran showed anti-oxidant content increment in adverse conditions warehouse which imposed by high seed moisture content and temperature. These genotypes also showed the highest germination and seed vigor after storage.
