چکیده مقاله :
به منظور بررسی جوانه‌زنی بذر تاتوره در شرایط متفاوت دمایی و نور پژوهشی در قالب طرح کاملاً تصادفی با 8 سطح دمایی (5، 10، 15، 20، 25، 30، 35، 40 درجه سانتی‌گراد) درشرایط نور مداوم و تاریکی مداوم با چهار تکرار در آزمایشگاه تحقیقاتی دانشگاه کشاورزی و منابع طبیعی رامین اهواز در سال 1395انجام شد. نتایج نشان داد که تیمار دمایی و نوری بر صفات درصد جوانه‌زنی، بنیه گیاهچه، طول ریشه‌چه و ساقه‌چه اثر معنی‌داری را نشان داد. دمای35 درجه سانتی‌گراد و شرایط نوری مداوم بالاترین درصد جوانه‌زنی را نشان داد. دماهای کاردینال جوانه‌زنی شامل دمای پایه، دمای بهینه و دمای حداکثر به ترتیب 6/7، 6/34 و 40 درجه سانتی‌گراد برآورد شد. بالاترین شاخص بنیه بذر در دمای 35 درجه سانتی‌گراد و شرایط نوری مداوم مشاهده شد. میانگین مدت جوانه زنی با افزایش دما روندی کاهشی را نشان داد و بیشترین میانیگین مدت جوانه‌زنی در 10 درجه سانتی‌گراد مشاهده شد. طول ساقه‌چه هم تحت تاثیر دماهای مختلف و شرایط نوری قرار گرفته و بیشترین طول ساقه‌چه در 30 درجه سانتی‌گراد مشاهده شد.
