چکیده مقاله :
به منظور بررسی تأثیر پیش تیمارهای مختلف بر ویژگی‌های جوانه‌زنی بذر و رشد گیاهچه چغندرقند (رقم فرناندو) تحت تنش شوری، پژوهشی در سال 1395 به صورت آزمایش فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار در آزمایشگاه علوم و تکنولوژی بذر دانشکده کشاورزی دانشگاه شاهد اجرا گردید. عوامل آزمایش شامل پیش تیمار سالسلیک اسید (3/0 و 6/0 میلی‌مولار)، هیدروپرایم (24 و 48 ساعت) و تنش شوری (0، 3-، 6- و 9- دسی زیمنس بر متر) بود. نتایج تجزیه واریانس اثر تسریع کننده‌ها بر ویژگی‌های جوانه‌زنی بذر چغندرقند نشان داد که اثر تسریع کننده‌ها بر صفات درصد جوانه-زنی کل، طول گیاهچه، وزن خشک گیاهچه، محتوی رطوبت نسبی، ضریب جوانه‌زنی و شاخص وزنی بنیه بذر در سطح احتمال یک درصد معنی‌دار بود. هم‌چنین اثر تنش شوری و نیز اثر توام پیش تیمار و تنش شوری بر تمامی صفات مذکور در سطح احتمال یک درصد معنی‌دار بود. نتایج مقایسه میانگین نشان داد که بیش‌ترین درصد جوانه‌زنی (9/12 درصد) مربوط به پیش تیمار هیدروپرایم 48 ساعت و تنش شوری 3- دسی زیمنس بر متر و کم‌ترین درصد جوانه‌زنی (75/6 درصد) مربوط به پیش تیمار سالسیلیک اسید 3/0 میلی‌مولار و تنش شوری 9- دسی زیمنس بر متر بود. بیش‌ترین و کم-ترین شاخص وزنی بنیه بذر به ترتیب مربوط به تیمار سالسیلیک اسید 6/0 میلی‌مولار و تنش شوری 9- دسی زیمنس بر متر (1/9850) و شاهد و تنش شوری 9- دسی زیمنس بر متر (730) بود. به طور کلی پیش تیمار سالسیلیک اسید 6/0 میلی‌مولار جهت افزایش بنیه بذر گیاه چغندرقند توصیه می‌شود.
