| برای بررسی دمای کاردینال جوانهزنی سه گونه دارویی پونهسا Nepata haussknechtii، N. pogonosperma و N. glomerulosa subsp. staffina و تعیین شرایط دمایی و زمانی مناسب کاشت آنها، آزمایشی فاکتوریل در قالب طرح کاملاً تصادفی در 3 تکرار در سال 1402 در آزمایشگاه تحقیقات تکنواوژی بذر بانک ژن منابع طبیعی ایران اجرا شد. سه مدل رگرسیونی غیرخطی شامل دندانمانند، دوتکهای و بتا، در هشت سطح دمایی (5، 10، 15، 20، 25، 30، 35 و 40 درجه سانتی گراد) برای توصیف پاسخ سرعت جوانهزنی بذر سه گونه پونهسا به دما مورد ارزیابی قرار گرفتند. از شاخصهای آماری مانند ریشه نتایج تجزیه واریانس (RMSE) و ضریب تبیین (R2) برای مقایسه مدلها استفاده شد. نتایج نشان داد در گونه N. haussknechtii مدل دندان-مانند با دمای پایه 01/9، دمای مطلوب تحتانی 20، دمای مطلوب فوقانی 25 و دمای سقف 21/36 درجه سانتیگراد و مقادیر R2 و RMSE به ترتیب 94/0 و 11/0؛ در گونه N. pogonosperma مدل دو تکهای با دمای پایه 9 ، دمای مطلوب 23 و دمای سقف 14/36 درجه سانتیگراد و میزان R2 و RMSE به ترتیب 95/0 و 31/0 ؛ و در گونه N. glomerulosa subsp. staffina مدل بتا با دمای پایه 84/9، دمای مطلوب 95/24 دمای سقف 37 درجه سانتیگراد و R2 و RMSE به ترتیب 99/0 و 03/0 از اطمینان بیشتری برخوردار بودند. نتایج این آزمایش نشان داد در گونههای مختلف پونهسا مورد مطالعه به علت سرعت رشد اولیه مشابه، دارای اوج جوانهزنی مشابهی هستند. | ||

| To investigate the cardinal temperature of three medicinal species of Nepata haussknechtii, N. pogonosperma and N. glomerulosa subsp. staffina and determining the appropriate temperature and time conditions for their planting, a factorial experiment was carried out in the form of a completely randomized design in three replications in 2023 in the Seed Technology Research Laboratory of the Gene Bank of Natural Resources of Iran. Three non-linear regression models, including dent-like, segmented and beta, were evaluated at eight temperature levels (5, 10, 15, 20, 25, 30, 35 and 40°C) to describe the response of the seed germination rate of three Nepeta species to temperature. Statistical indices such as root mean square (RMSE) and coefficient of explanation (R2) were used to compare the models.The results showed that the parameters estimated using the dent-like model in N. haussknechtii include base temperature, optimal lower temperature, optimal upper temperature, ceiling temperature, R2 and RMSE values were 9.01°C, 20°C, 25°C, 36.21°C, 0.94 and 0.11, respectively; segmented model in the N. pogonosperma include base temperature, optimal temperature, ceiling temperature, R2 and RMSE values were 9°C, 23°C, 36.14°C, 0.95 and 0.31, respectively; and beta model in the N. glomerulosa subsp. staffina include base temperature, optimal temperature, ceiling temperature, R2 and RMSE values were 9.84°C, 24.95°C, 37°C, 0.99 and 0.03, respectively had more confidence. The results of this experiment showed that in the different studied species of Nepeta, due to the similar initial growth rate, they have the same germination peak. | ||
