| چکیده | ||
| به منظور القاء جوانه‌زنی بذر و واکنش رشدی گیاهچه گل پامچال به تیمارهای مختلف خراش‌دهی مکانیکی و پیش‌تیمار شیمیایی، آزمایشی به صورت طرح کاملاً تصادفی با تیمارهای شاهد (بذر بدون تیمار)، خراش‌دهی بذر (سمباده نرم به مدت سه دقیقه)، تیمار بذر با آب گرم 70 و 90 درجه سانتی‌گراد، پرایمینگ با نیترات پتاسیم 2 و 4 درصد، اسید جیبرلیک با غلظت‌های 250 و 500 میلی‌گرم در لیتر در سه تکرار در سال 1392 انجام شد. نتایج نشان داد که تیمارهای خراش‌دهی، آب گرم 70 و 90 درجه سانتی‌گراد، جیبرلیک اسید 250 و 500 میلی‌گرم در لیتر درصد ظهور گیاهچه را نسبت به شاهد افزایش دادند. بیشترین درصد ظهور گیاهچه در تیمار جیبرلیک اسید 250 میلی‌گرم در لیتر بود. تیمار بذرها با نیترات پتاسیم 2 و 4 درصد متوسط زمان ظهور گیاهچه را نسبت به شاهد به ترتیب به میزان 2/61 و 7/51 درصد کاهش دادند. بیشترین ضریب سرعت جوانه زنی معادل 0946/0 و 0926/0 از تیمارهای نیترات پتاسیم 2 و 4 درصد حاصل شد. بیشترین طول گیاهچه (53/5 سانتی‌متر)، وزن خشک گیاهچه (0299/0 گرم) و شاخص بنیه وزنی گیاهچه (51/1) از تیمار جیبرلیک اسید 250 میلی‌گرم در لیتر حاصل شد. استفاده از تیمارهای خراش‌دهی، آب گرم 70 و 90 درجه سانتی‌گراد، تیمارهای جیبرلیک اسید 250 و500 میلی‌گرم در لیتر بطور معنی‌داری شاخص بنیه وزنی گیاهچه را نسبت به شاهد افزایش دادند. بطور کلی نتایج این تحقیق نشان داد که پیش تیمار بذر گل پامچال با جیبرلیک اسید 250 میلی‌گرم در لیتر باعث بهبود جوانه زنی و خصوصیات رشدی گیاهچه شد. | ||

| In order to seed germination induction and response of seedling growth of Primula vulgaris to different treatments of mechanical scarification and chemical pre-treatment, an experiment was carried out in completely randomized design with treatments of control, seed scarification (for 3 minute), warm water 70 and 90˚C, priming with potasium nitrate at the rate of 2 and 4%, gibberellic acid at the concentration of 250 and 500 mg/L with three replicates in 2013. The results showed that treatments of seed scarification, warm water 70 and 90˚C and gibberellic acid of 250 and 500 mg/L increased the seedling emergence percentage compared to the control. The maximum of the daily emergence percentage recorded from gibberellic acid of 250 mg/L. Seed treatment with potasium nitrate of 2 and 4% decreased the mean emergence time by 61.2 and 51.7% compared with the control, respectively. The highest emergence rate coefficient equal to 0.094 and 0.092 was achieved from seed treatment with potasium nitrate of 2 and 4% .The maximum seedling length (5.53 cm), seedling dry weight (0.029 g), seedling vigor weight index (1.15) was obtained at gibberellic acid of 250 mg/L treatment. Treatments of seed scarification, warm water 70 and 90˚C, gibberellic acid at the concentration of 250 and 500 mg/L increased seedling vigor weight index compared to the control, significantly. In general, seed pre-treatment of Primula vulgaris with gibberellic acid of 250 mg/L was improved germination and seedling growth indices. | ||
