چکیده مقاله :
به‌منظور شناخت عوامل اکو فیزیولوژیکی مؤثر بر خواب و ایجاد شرایط بهینه برای جوانه زنی بذر گیاه دارویی کهورک (Prosopis fracta)، آزمایشی در قالب طرح کاملاً تصادفی با سه تکرار در آزمایشگاه علوم و تکنولوژی بذر دانشکده کشاورزی دانشگاه شاهد با تیمارهایی که شامل شاهد، 80WS (بن ماری 80 درجه سانتی گراد به مدت سه روز)، 65WS (بن ماری 65 درجه سانتی گراد به‌مدت سه روز)، 80W (آون 80 درجه سانتی گراد به مدت سه روز)، 65W (آون 65 درجه سانتی گراد به‌مدت سه روز)، (65 WS)+ (5CS) (چینه سرمایی با دمای پنج درجه سانتی گراد و سپس بن ماری 65 درجه سانتی گراد به‌مدت سه روز)، (80WS) + (5CS) (چینه سرمایی با دمای پنج درجه سانتی گراد و سپس بن ماری 80 درجه سانتی گراد به‌مدت سه روز)، (65W)+(5 CS) (چینه سرمایی با دمای پنج درجه سانتی گراد و سپس آون 65 درجه سانتی گراد به‌مدت سه روز) و (80W)+ )5 CS) (چینه سرمایی با دمای پنج درجه سانتی گراد و سپس آون 80 درجه سانتی گراد به‌مدت سه روز) بودند، اجرا شد. نتایج این بررسی نشان داد که بذور تیمار شده با (65 WS)+ (5CS)، بالا ترین وزن تر گیاهچه (63/1 گرم) و خشک گیاهچه (19/1 گرم) و تیمار های شاهد، 80WS و (80WS)+( 5CS) کمترین وزن خشک و تر گیاهچه (5/0 گرم) را به خود اختصاص دادند. بیش ترین بنیه وزنی بذر مربوط به تیمار (65 WS)+ (5CS) (26/245) بود. هم چنین تیمار (65 WS)+ (5CS) باعث شکست خواب سریع بذر و افزایش سرعت جوانه زنی گردید. لذا مؤثر ترین تیمار جهت شکست خواب بذر کهورک، تیمار بن ماری 65 درجه سانتی‌گراد توصیه می شود.
