   در یک تحقیق گلخانه‏ای، اثرات تنش شوری ناشی از سدیم کلرید بر روی برخی ویژگی‏های فیزیولوژیک و ترکیب شیمیایی در گیاه شوید در یک طرح آماری کاملاً تصادفی در پنج سطح شوری صفر، 25، 50، 75 و 100 میلی‏مولار با چهار تکرار مورد بررسی قرار گرفت. کشت دانه‌ها در گلدان‏های پلاستیکی و شرایط گلخانه و آبیاری گیاهان به کمک محلول غذایی هوگلند صورت گرفت. در پایان مرحله رشد، مقادیر وزن خشک گیاه، طول ساقه و سطح برگ، سدیم و پتاسیم و کلر برگ‏ها، کلروفیل کل برگ‏ها، کل قندهای محلول اندازه‏گیری شد. نتایج نشان داد که با افزایش درجه شوری، مقدار کلروفیل کل برگ‏ها، وزن خشک گیاه و سطح برگ کاهش معنی‏دار پیدا کرده است، ولی در مقابل میزان کل قندهای محلول افزایش یافت. هم‏چنین با افزایش درجه شوری، پتاسیم برگ‏ها به طور معنی‏دار کاهش پیدا کرد و مقادیر سدیم و کلر برگ‏ها به‏صورت معنی‏دار افزایش یافت که باعث مسمومیت یونی به ویژه در سطوح بالای شوری گردید. افزایش قندهای محلول همراه با افزایش سطح شوری اهمیت آن‏ها را در تنظیم اسمزی نشان می‏دهد.

چکیده [English]

In order to study the effect of NaCl salinity on some phisiological characteristics and accumulation of some mineral and organic matters in dill plant, Anethum graveolens L., a completely randomized design was arranged with five salinity levels (0, 25, 50, 75 and 100 mM NaCl) with four replications. Seeds culturing was done in greenhouse and plants irrigated by Hoagland nutrition solution. Total dry weight, stem length, leaf area, total leaf chlorophyll, total soluble sugars and Na+, K+ and Cl- were measured at the final leaf growth stage. Results showed that total chlorophyll, dry weight, K+ in leaves, leaf area, and stem length significantly decreased with increasing salinity levels, while total soluble sugars increased. In addition, the significant increase of Na+ and Cl- accumulation in the leaves, particularly at high salinity levels caused nutrient deficiency and ionic toxicity. The sugar accumulation at high salinity levels showed their importance in osmoregulation.
