| به منظور ارزیابی میزان جوانه زنی توده های بذر در مراحل اولیه شروع آزمون جوانه زنی، به عنوان یک روش سریع برای ارزیابی بنیه بذرها، نمونه بذر از بیست توده بذر کلزا، از چهار رقم مختلف (اکاپی، هایولا 401، اپرا و لیکورد) که در سالهای 1386 تا 1390 تولید شده بودند، تهیه شد. آزمون جوانه زنی استاندارد بذرها در آزمایشگاه تحقیقات بذر و آزمون توانایی ظاهرشدن گیاهچه این توده های بذر در خاک در گلخانه تحقیقاتی دانشگاه فردوسی مشهد انجام شد. نتایج نشان داد که درصد جوانه زنی نهایی، درصد گیاهچه عادی و متوسط زمان جوانه زنی توده های بذر به ترتیب با ضریب همبستگی (r) 0.84، 0.89 و0.82 با ظاهرشدن بذرها در خاک همبستگی داشتند. تعداد بذرهای جوانه زده در مراحل ابتدایی جوانه زنی، بطورمعنی داری با ویژگی های جوانه زنی و همین طور ظاهرشدن گیاهچه بذرها همبستگی داشت، به طوریکه درصد جوانه زنی توده های بذر در روز دوم و سوم، با متوسط زمان جوانه زنی به ترتیب با ضریب همبستگی (r) 0.97 و0.92، با درصد گیاهچه عادی 0.88 و0.81 و با درصد ظاهرشدن گیاهچه در خاک به ترتیب 0.83 و 0.83 همبستگی داشتند. بنابراین می توان نتیجه گرفت که درصد بذرهای جوانه زده در مراحل ابتدایی شروع جوانه زنی، می تواند به عنوان شاخصی برای ارزیابی بنیه بذر مورد استفاده قرار گیرد. | ||

| In order to evaluate of seed lots germination in early stages of germination test beginning as a rapid method to evaluate the seed vigour, seed samples from twenty seed lots of oilseed rape, from four varieties (Okapy, Hyola 401, Opera and Licord) produced in 1386 to 1390 was provided. Standard germination test carried out in Seed Research Laboratory and soil emergence of seed lots examined in the Research Greenhouse of the Ferdowsi University of Mashhad, Iran. The results showed that the percentages of final germination and normal seedlings and mean germination time had a high correlation (r = 0.84, 0.89 and 0.82, respectively) with the soil emergence of the lots. Germinated percentages in the early days of the test had significant correlation with characteristics of germination and soil emergence of the seedlots. So that, the percentages of germinated seeds on days two and three, correlated with mean germination time (r= 0.97 and 0.92) and with normal seedlings (r = 0.88 and 0.81) and with soil emergence (r = 0.83 and 0.83) respectively. Therefore, the percentages of germinated seeds in the early stages of germination can be used as an alternative and rapid method to assess the final germination, normal seedlings, mean germination time hence seed vigour of oilseed rape. | ||
