| به دلیل استفاده از بذور چمن وارداتی و به طبع تحمیل هزینه های سنگین خرید بذر و سازگاری کم آنها با شرایط اقلیمی کشور، توجه به اکوتیپهای چمن بومی ایران حائز اهمیت است. یکی از دلایل توجه اندک به بذور بومی، عدم سبز شدن سریع و یکنواخت آنها خصوصا در شرایط تنش خشکی است. هدف پژوهش، بررسی پیشتیمار اسید سالیسیلیک (1/0، 5/0، 1 و 5/1 mM)، کلرید سدیم (15، 30 و 45ds/m ) و آب مقطر و مقایسه آن با شاهد (بدون پیش تیمار) روی بذر چمن فتان بلند بومی منطقه گزبرخوار اصفهان در شرایط تنش خشکی شدید، متوسط و خفیف بود. بدین منظور صفات درصد سبز شدن، میانگین زمان سبز شدن، ارتفاع بخش هوایی، وزن خشک گیاه، محتوای آب نسبی برگ، نشت الکترولیت، میزان کلروفیل کل و میزان کاروتنوئید گیاهچهها اندازهگیری شد. نتایج نشان داد پیش تیمار با اسید سالیسیلیک 5/0 mM در شرایط تنش متوسط سبب افزایش معنیدار میزان سبز شدن بذور (10/96%) و در شرایط تنش خفیف سبب کاهش زمان سبز شدن گیاهچهها (70/3 روز) شد. اگر چه گیاهان تیمار ذکر شده در سایر صفات تفاوت معنیداری با تیمار شاهد نداشتند، نظر به اهمیت صفات میزان و زمان سبز شدن برای بذور بومی اصلاح نشده، میتوان این پیش تیمار را برای بهبود صفات سبز شدن بذور فتان بلند گزبرخوار توصیه نمود. | ||

| چکیده [English] | ||
| Due to high expenses of imported lawn seeds and low adaptability of them to climatic conditions of Iran, paying attention to native ecotypes of turf grasses is important. One of the reasons for paying less attention to the seeds of native turf grasses is their lack of rapid and uniform germination rate especially under drought stress conditions. The aim of this study was to investigate the effect of seed priming using salicylic acid (1/0, 5/0, 1 and 5/1 mM), sodium chloride (15, 30 and 45ds /m) and distilled water compared to the control treatment on tall fescue native to GazBorkhar (Isfahan province) under mild, moderate and severe drought stress conditions. For this purpose, seed emergence, mean emergence time, shoot height, plant biomass, relative water content, electrolyte leakage, total chlorophyll content and carotenoid content were measured. The results showed seed priming using salicylic acid 0.5 mM significantly increased the seed emergence rate (96.10%) in moderate stress conditions and reduced the time to emerge (3.70 day) in mild stress conditions. Although the plants treated with 0.5 mM salicylic acid did not show significant differences with the control treatment in other characteristics, considering the significance of the amounts and rates of seed emergence in native turf grasses, this prime treatment can be recommended to improve emergence percentage of the seeds of Festuca arundinacea ecotype Gazborkhar. | ||
