| به‌منظور مطالعه رابطه میان اندازه و پیری بذر بر میزان دماهای کاردینال جوانه‌زنی کلزا رقم هایولا 50، آزمایشی به‌صورت فاکتوریل در قالب طرح پایه کاملاً تصادفی با 3 تکرار اجرا شد. عامل اول، اندازه بذر بر اساس قطر ( 4 /1، 8/1، 2 و 2/2 میلی‌متر) در نظر گرفته شد. عامل دوم سطوح مختلف کیفیت بذر با استفاده از 6 سطح پیری تسریع شده (0، 24، 48، 72، 96 و 120 ساعت در دمای 40 درجه سلسیوس و رطوبت نسبی %100) و عامل سوم نیز دمای جوانه‌زنی (0، 5، 10، 15، 20، 25، 30، 35 و 40 درجه سلسیوس) بود. به منظور برآورد دماهای کاردینال مورد نیاز برای 50 درصد جوانه‌زنی از مدل‌های بتا، بتای اصلاح شده، دندانه‌ای و دو تکه‌ای استفاده شد. نتایج نشان داد، مدل بتا نسبت به سایر مدل‌ها سرعت جوانه‌زنی را بهتر برآورد کرده است و پیری و اندازه‌های مختلف بذر بر مدل تغییرات تاثیری نداشت. دمای پایه در اندازه‌های 4/1 در حدود 15/1 درجه سلسیوس بوده و با افزایش اندازه بذر تا 2/2 میلی متر به 11/0 درجه سلسیوس کاهش یافت. نوسانات دمای بهینه در حدود 37/21 تا 58/21 درجه سلسیوس و دمای بیشینه 2/40 تا 8/40 درجه سلسیوس بود. همچنین مشخص شد، بذرها با اندازه‌های مختلف از نظر ترمال‌تایم دارای تفاوت معنی‌دار نبوده و پیری موجب افزایش دمای پایه جوانه‌زنی و ضریب ترمال‌تایم و کاهش دمای بهینه و بیشینه شدکه این می‌تواند ضرورت تاخیردر تاریخ کاشت در مناطق سردسیری و یا کشت زود هنگام در مناطق گرمسیری در این نوع بذرها را نشان دهد. | ||

| To study the relationship between seed size and aging on cardinal temperatures of canola cv. Hyola 50, seed germination an experiment was conducted based on a randomized complete design with three replications. Seeds were classified in to four groups based on their diameter (1.4, 1.8, 2 and 2.2 mm) and considered as the first experimental factor. The Second factor was various durations of accelerated aging treatment (0, 24, 48, 72, 96 and 120 hours (40oC, RH=100%) and the third factor was nine constant temperatures in which seeds were germinated (0, 5, 10, 15, 20, 25, 30, 35 and 40 ˚C). Cardinal temperatures were quantified for germination fraction of 50% using four nonlinear model: beta, beta modify, dent-like and segmented. The result indicted beta model better described responses germination rate to temperature compared with others models and accelerated aging and sizes did not affect the change model base temperature was about 1.15 OC in sizes 1.4 mm and increase in size to 2.2 mm deceased to 0.11 OC. The optimal temperature range was about 21.37 to 21.58 OC and the maximum temperature was 40.2 to 40.8 OC. it was also found that different seed sizes did not have a significant difference in terms of thermal time and deterioration increased the basal germination temperature and thermal time coefficient and reduced the optimal and maximum temperature, that it can show necessity delay in planting date in cold areas or early planting in tropical areas in these types of seeds. | ||
