| چکیده | ||
| گیاه گاوزبان (Borago officinalis L.) یکی از قدیمیترین گیاهان دارویی است که در ایران و سایر نقاط دنیا مورد توجه میباشد. لذا با توجه به اهمیت دارویی این گیاه، وفور اراضی خشک، بررسی توانایی مقابله با تنشهای محیطی توسط این گیاه، ضروری به نظر میرسد تا مطالعه ای با اهداف اثرات تنش آبی برمقدار پروتئین، پرولین و عناصر پرمصرف N,P,S ,K و رشد در شرایط هیدروپونیک انجام گیرد. نتایج نشان داد پروتئین و وزنتر و خشک ریشه و بخشهای هوایی گیاهان تحت تیمار تنش آبی نسبت به گیاهان شاهد کاهش یافت که این کاهش در بخشهای هوایی معنیدار بود، مقدار K در ریشه کاهش و در بخشهای هوایی افزایش و مقادیر عناصر پر مصرف S, P, N در ریشه افزایش و در بخشهای هوایی کاهش یافت. بیوسنتز پرولین در برگ و ریشه با اعمال تنش خشکی نسبت به شاهد افزایش معنیداری یافت. تنش خشکی باعث کاهش مقدار پروتئین در اندام هوایی و ریشه نسبت به گیاه شاهد شد. | ||

| چکیده [English] | ||
| Borago officilalis, one of the oldest medicinal plants that is consumed in iran and other regions word. The considering importance of medicinal Borago officilalis, abundance of dry land, confroting ability with environmental stress by this plant, it seems necessary until done one study with the folowing goals. The chief goal of this research is to look for any effects of hydro stresses on proline biosynthesis, protein quantity, growth and change high consumption elements like K, S, P & N at hydroponic conditions. According to the results, there was a reduction in the weight of dry / wet root and aerial sections in any plants under hydro stress treatment in comparison with witness ones. The mentioned reductions were significant at aerial sections. There was a decrease in K quantity at root section with an increase at aerial parts. Also there was an increase in quantity of high consumption elements like N, P & S of root and a reduction of the same at aerial sections. Drought stress decreases the amount of protein in the plant shoots and roots compared to control. Proline contents in leaves and roots significantly increased under drought stress compared to control. | ||
