| چکیده | ||
| درجه حرارت یکی از مهم ترین عوامل محیطی موثر بر جوانهزنی بذور محسوب میشود و بنابراین اثر متقابل دمای محیط و جوانه زنی یکی از عوامل اصلی در پیش بینی زمان جوانه زنی و بویژه مدلسازی است. به این منظور آزمایشی در قالب طرح کاملا تصادفی با 4 تکرار و 11 سطح تیمار دما (3، 5، 7، 10، 15، 20، 25، 30، 35 و 40 و 45 درجه سانتیگراد) روی بذور همیشه بهار در آزمایشگاه تحقیقات بذر دانشگاه اسلامی واحد مهاباد به اجرا درآمد. به منظور تعیین دماهای کاردینال سه مدل رگرسیون غیر خطی تابع دو تکه ای، تابع بتا و تابع 5 پارامتره بتا مورد آزمون قرار گرفتند. نتایج نشان داد که تاثیر دما بر سرعت، درصد و یکنواختی جوانه زنی بذر معنی دار بود. بالاترین درصد و یکنواختی جوانه زنی در دمای 15 درجه سانتیگراد مشاهده گردید، درحالیکه بیشترین سرعت جوانه زنی در دمای 20 درجه سانتیگراد بدست آمد. اگرچه اختلاف چندانی بین مدل های برازش یافته در تخمین دماهای کاردینال وجود نداشت ولی مدل دو تکه ای به واسطه دارا بودن کمترین ریشه میانگین مربعات خطا و ضریب تغییرات و بیشنرین ضریب تبیین و ضریب همبستگی بهترین مدل برای تخمین دماهای کارینال همیشه بهار در نظرگرفته شد. بنابراین دمای پایه جوانه زنی گیاه همیشه بهار 3.35، دمای مطلوب 20.84 و دمای سقف 40.94 درجه سانتیگراد بدست آمد ضمن اینکه ماکزیمم سرعت جوانه زنی نیز(0.010: rmax بر ساعت) بود. | ||

| Temperature is one of the most effective and important environmental agents on seed germination, thus interaction effect of germination with temperature is very important in prediction of germination time and modeling especially. A completely randomized design experiment performed in seed research laboratory of Islamic Azad University, Mahabad Branch with four replications which temperature treatment were 11 levels as: 3, 5, 7, 10, 15, 20, 25, 30, 35, 40 and 45 0C. Three nonlinear regression models as Beta, 5-Parametric Beta and Segmented functions tested. Results revealed that temperature had a significant effects of rate, uniformity and germination percent. The highest uniformity and germination percentage were detected in 15 0C, but the highest value of rate of germination obtained in 20 0C. Although, there was no significant difference between practiced models in estimation of cardinal temperatures, however, the segmented model which had the less RMSE, CV and the more R2 and correlation coefficients than the others, was a better model and thus, cardinal temperatures including base, optimum and ceiling temperatures were 3.35, 20.84 and 40.94 0C, respectively. Also, the maximum germination rate (rmax ) was 0.010 h-1. | ||
