| چکیده | ||
| هدف تحقیق حاضر بررسی تیمارهای مختلف خراش‌دهی بذر بر سبز شدن بذر سنجد می‌باشد. این آزمایش در شهر سمنان صورت پذیرفت. تیمار خراش‌دهی بذر در قالب طرح کاملاً تصادفی با سه تکرار (هر تکرار12 بذر) انجام شد. تیمارهای مورد استفاده برای شکستن خواب فیزیکی بذر سنجد شامل تیمار شاهد، NaOH 60 % با مدت زمان 20 و 30 دقیقه، H2SO4 98 % با مدت زمان 20 و 30 دقیقه، آب‌اکسیژنه 1% با مدت زمان 10 و 20 دقیقه، خراش‌دهی فیزیکی، آب جوش با مدت زمان 15 دقیقه و یخ‌آب(5 روز در دمای صفر درجه و سپس24 ساعت در دمای 25 درجه به مدت 3 روز) بود. نتایج تحقیق نشان داد که در بین تیمارهای سبز شدن بذر سنجد شامل درصد سبز شدن ، سرعت سبز شدن ، شاخص بنیه بذر و میانگین زمان سبز شدن و نیز صفات سبز شدن بذر از جمله طول ساقه‌چه، تعداد برگچه، طول ریشه‌چه و شاخص‌های سبزشدن بذر مورد اندازه‌گیری اختلاف معنی‌داری وجود داشت. بیشترین درصد سبز شدن به میزان 67/88 درصد در تیمار اسید سولفوریک 98 درصد به مدت 20 دقیقه بود. همچنین بیشترین شاخص بنیه بذر (96درصد)، میانگین طول ریشه‌چه(48 میلی‌متر)، میانگین طول ساقه‌چه (60 میلی‌متر) و میانگین تعداد برگچه(7/5 عدد) نیز در این تیمار مشاهده گردید. در مجموع نتایج بدست آمده نشان داد که در تمامی پارامترهای مورد بررسی تیمار اسید سولفوریک 98 درصد به مدت 20 بالاترین مقادیر بدست آمد ولی دو تیمار یخ‌آب و تیمار آب جوش، سبب ممانعت از سبز شدن بذرهای سنجد شدند. | ||

| چکیده [English] | ||
| Due to the fact that Elaeagnus angustifolia seed has a hard shell, the present study was conducted to investigate the types of appropriate treatments for germination of Elaeagnus angustifolia seed. The experiment was done in Semnan. Seed scarification performed in a completely randomized design with three replications (12 seed per replication). Experimental treatments to break dormancy of Elaeagnus angustifolia seed included control, 60% sodium hydroxide for 20 and 30 minutes, 98% sulfuric acid for 20 and 30 minutes, 1% oxygenated water for 10 and 20 minutes, physical scraping, 90°C boiling water for 15 minutes and ice water(5 days at a temperature of zero degrees and then 24 hours at a temperature of 25 degrees for 3 days). The results showed that there was a significant difference at the level of 1 % between the germination treatments of Elaeagnus angustifolia seed including of germination percent, germination rate, and mean time of germination seed vitality index, and seed vegetative traits such as root length, stem length, number of leaflets and seed germination indices. The highest germination percentage was 88.67% in 98% sulfuric acid treatment for 20 minutes. Also, the highest seed vigor index (96%), mean root length(48 mm), mean stem length(60 mm) and average number of leaflets (5.7 number) were observed in this treatment. Totally, the results showed that in all parameters examined that Sulfuric acid treatment of 98% for 20 years obtained the highest values, but two treatments of ice water and boiling water prevented the germination of Oleaster seeds. | ||
