چکیده مقاله :
شوری آب و خاک تهدیدی جدی برای کشاورزی در مناطق خشک و نیمه خشک مانند ایران محسوب می‌شود. در سال های اخیر بکارگیری روش هایی که موجب افزایش تحمل گیاه به تنش شوری گردد مورد توجه محققین قرار گرفته است. به منظور بررسی تأثیر اسید هیومیک تجاری بر جوانه زنی و رشد اولیه سورگوم علوفه ایتحت سطوح مختلف تنش شوری آزمایشی به صورت فاکتوریل در قالب طرح کاملا تصادفی در چهار تکرار در آزمایشگاه گیاه شناسی دانشگاه یزد در سال 1395 انجام شد. فاکتور اول تنش شوری با سه سطح شامل 0، 120 و 240 میلی مولار کلرید سدیم و فاکتور دوم اسید هیومیک با سه سطح شامل 0، 5/0 و 1 گرم در لیتر در نظر گرفته شد. نتایج نشان داد که با افزایش سطوح تنش شوری درصد و سرعت جوانه زنی، متوسط جوانه زنی روزانه، بنیه بذر، طول ریشه چه و ساقه چه و همچنین وزن تر و خشک آنها به‌طور معنی دار کاهش یافتند. به‌طوری‌که شاخص های درصد و سرعت جوانه زنی، بنیه بذر، طول ریشه چه و ساقه چه در تنش شوری 120 میلی‌مولار نسبت به تیمار شاهد به‌ترتیب 12، 24، 52، 51 و 33 درصد کاهش یافت. کاربرد اسید هیومیک با غلظت های 5/0 و 1 گرم در لیتر باعث کاهش اثرات منفی ناشی از تنش شوری به‌ویژه در سطح 120 میلی مولار شد. مصرف اسید هیومیک با غلظت 5/0 گرم در لیتر توانست سرعت جوانه زنی، شاخص بنیه بذر و طول ساقه‌چه و ریشه چه در تنش شوری 120 میلی مولار به‌ترتیب 20، 25، 32 و 28 درصد افزایش دهد. با این حال پیشنهاد می شود که مطالعات تکمیلی در این زمینه در شرایط گلخانه و مزرعه صورت پذیرد.
