ملخص المقالة :
دما در دوره گلدهی و دانهبندی شاخص بسیار با اهمیتی برای تخمین پتانسیل عملکرد دانه کلزا محسوب میشود. به منظور ارزیابی تاثیر مواجهه با تنش گرمای ناشی از تاخیر در کاشت بر خصوصیات زراعی ژنوتیپهای مختلف کلزا (شامل هایولا420، هایولا50، هایولا60، سان37، سان34 و دلگان)، دو آزمایش جداگانه در دو تاریخ کاشت متداول (21 آبان ماه) و تاخیری (26 آذر ماه)، هر کدام در قالب طرح بلوکهای کامل تصادفی با سه تکرار در سال زراعی 96-1395 در مزرعه تحقیقاتی دانشگاه آزاد اسلامی واحد رامهرمز اجرا شد. هر تاریخ کاشت به عنوان یک محیط در نظر گرفته شد و دادههای حاصل در نهایت تجزیه مرکب شدند. نتایج نشان داد که با تاخیر در کاشت و وقوع تنش گرما در مرحله گلدهی و دانه بستن، تعداد گل باز شده روی ساقه اصلی، درصد گلهای منتهی به خورجین، تعداد خورجین در بوته، تعداد شاخههای فرعی، تعداد دانه در خورجین، وزن هزار دانه، طول خورجین، ارتفاع بوته و طول دوره زایشی ژنوتیپها کاهش یافت و منجر به کاهش معنیدار عملکرد دانه شد. کاهش تعداد خورجین در بوته بیشترین سهم در کاهش عملکرد دانه را به خود اختصاص داد. در تاریخ کاشت متداول، عملکرد دانه در هایولا 420 و سان 34 بیشتر از سایر ژنوتیپها بود و در شرایط تنش گرمای ناشی از تاخیر در کاشت، هایولا50 و سپس سان 34 بیشترین و دلگان کمترین عملکرد دانه را به خود اختصاص دادند. کمترین درصد کاهش عملکرد ناشی از تاخیر در کاشت به هایولا50 تعلق داشت (55 درصد) و بر اساس شاخص حساسیت به تنش، ژنوتیپی نیمه متحمل به تنش گرمای انتهای فصل شناخته شد. در تاریخ کاشت متداول، ژنوتیپهایی که سریع تر به مرحلهگلدهی رسیدند ولی دوره گلدهی طولانیتری داشتند از عملکرد بالاتری برخوردار بودند، در مقابل، در تاریخ کاشت تاخیری همبستگی منفی و معنیداری بین طول دوره گلدهی با تعداد خورجین در بوته، تعداد دانه در خورجین و عملکرد دانه مشاهده شد. ژنوتیپ سان34 در هر دو تاریخ کاشت متداول و تاخیری از عملکرد بالایی برخوردار بود و به عنوان ژنوتیپی مناسب برای دستیابی به عملکردی پایدار در منطقه رامهرمز می تواند مورد توجه قرار گیرد.
