| چکیده | ||
| پرایمینگ نقش مهمی بر بنیه بذر و گیاهچه دارد. عامل اول این پژوهش؛ دو رقم برنج (خزر و هاشمی) و عامل دوم؛ ده سطح تیمار پرایمینگ (T1-T10) بود. آزمون‌های بنیه بذر و ارزیابی گیاهچه بر اساس دستورالعمل ISTA انجام شد. نتایج نشان داد که، رقم خزر از نظر وزن تر ریشه‌چه (7/14 میلی‌گرم) و تعداد ریشه‌چه (5)، نسبت به رقم هاشمی برتر بود. مدت زمان لازم (ساعت) برای رسیدن به 50% جوانه‌زنی (R50) در رقم خزر، 50 ساعت و در رقم هاشمی، 41 ساعت بود که بر این اساس رقم هاشمی از یکنواختی بالاتری در جوانه‌زنی برخودار است. تیمار پرایمینگ با KCl بالاترین مقدار هدایت الکتریکی را ایجاد کرد. کمترین زمان لازم برای رسیدن به 5، 10 و 50 درصد جوانه‌زنی به ترتیب با 13، 16 و 32 ساعت، مربوط به تیمار هایدروپرایمینگ بود. همچنین بیشترین سرعت جوانه‌زنی مربوط به تیمار هایدروپرایمینگ بود. کمترین زمان تا رسیدن به 95 درصد جوانه‌زنی با 66 ساعت، در تیمار هایدروپرایمینگ رقم هاشمی محاسبه شد. بیشترین استقرار گیاهچه در روز بیستم بعد از کاشت در مزرعه مربوط به بذر بدون تیمار پرایمینگ بود. تیمار هایدروپرایمینگ به دلیل هزینه پایین و اثرگذاری مثبت در سرعت و یکنواختی جوانه‌زنی در رقم هاشمی به کاربران توصیه می‌شود. | ||

| Priming has an important role on vigority of seed and plantlet. The first factor was two rice cultivars (Khazar and Hashemi) and the second one was ten priming treatment levels (T1-T10). Examination of seed vigority and seedling assessment was carried out according to the ISTA protocol. Results showed that the root fresh weight (14.7 mg) and root number (5) was higher in Khazar than those of Hashemi. The required time (hour) for reach to 50% germination (R50) was 50 hours for Khazar and 41 hours for Hashemi, accordingly Hashemi was more uniformity in germination than Khazar. Priming treatment with KCl created the highest electrical conductivity. The minimum time duration to reach to 5, 10 and 50% of germination with 13, 16 and 32 hours, respectively was related to hydro-priming treatment. Also, the highest germination rate was related to hydro-priming. Minimum required time duration until reach to 95% germination with 66 hours was calculated in hydro-priming of Hashemi. Most plantlet establishment on 20th day after cultivation in field was related to without priming-treated seed. Hydro-priming treatment is recommended to user due to low cost and positive effectiveness on acceleration and uniformity of germination in Hashemi. | ||
