| چکیده | ||
| انتقال مجدد هیدراتهای کربن از طریق اندامهای هوایی یکی از عوامل مؤثر در پُرشدن دانه برنج میباشد. به‌منظور تعیین سهم انتقال مجدد ماده خشک اندامهای هوایی بر عملکرد دانۀ برنج، پژوهشی با هفت ژنوتیپ امیدبخش و دو رقم شاهد در قالب طرح بلوکهای کامل تصادفی با سه تکرار در دو سال زراعی 1396 و 1397 در ایستگاه تحقیقات برنج شهید شیرودی شهرستان تنکابن اجرا شد. نتایج نشان داد که از نظر میزان انتقال مجدد ماده خشک از طریق برگ پرچم، ساقه و کل اندام هوایی در سطح احتمال یک درصد و از طریق سایر برگها در سطح احتمال پنج درصد تفاوت آماری معنیداری میان ژنوتیپها وجود داشت. مقایسه میانگین بیانگر آن است که بیش‌ترین میزان انتقال مجدد ماده خشک از برگ پرچم متعلق به ژنوتیپ 952 با 56 گرم در مترمربع بود. حداکثر انتقال مجدد کربوهیدراتها از طریق سایر برگها، ساقه و کل اندام هوایی به‌ترتیب به مقدار 123، 230 و 398 گرم در مترمربع به ژنوتیپ 953 اختصاص داشت. بیش‌ترین عملکرد دانه مربوط به ژنوتیپ 952 با 7206 کیلوگرم در هکتار بود. نتایج همبستگی نشان داد که عملکرد دانه با انتقال مجدد ماده خشک از راههای برگ پرچم، ساقه، اندام هوایی و وزن هزاردانه با ضریب 37/0، 55/0، 51/0 و 44/0 همبستگی مثبت و معنیدار داشت. با توجه به عملکرد و میزان انتقال مجدد ماده خشک دو ژنوتیپ 952 و953 ژنوتیپهای مناسبی برای ادامه فعالیتهای تحقیقاتی به‌منظور معرفی رقم جدید برنج به‌ویژه در شرایط کمبود آب و تنش گرما میباشند. | ||

| چکیده [English] | ||
| The remobilization of carbohydrates in shoots is one of the effective factors to grain filling in rice. To determine the contribution of dry matter remobilization of shoots in different rice genotypes, a research has been carried out with seven rice genotypes and two controls in RCBD design with three replications during 2017-2018 at rice research station of Shahid Shiroodi in Tonekabon county. Results show that among all genotypes, rate of dry matter remobilization via the flag leaf, stem, and total shoot has differed significantly at (p<0.01) percent and from other leaves at (p<0.05) percent level. Mean comparison among the genotypes indicates that the highest dry matter remobilization from flag leaf belongs to Genotype 952 with 56 g.m-2. The maximum carbohydrates remobilization in other leaves, stem and total shoots are assigned to Genotype 953 at 123, 230, and 398 g.m-2, respectively. Highest grain yield belongs to Genotype 952 with 7206 kg.ha-1. Correlation analysis results show that grain yield is positively and significantly correlated with dry matter remobilization from flag leaf, stem, and total shoots, as well as 1000-grain weight, having coefficients of 0.37, 0.55, 0.51, and 0.44, respectively. As a result of yield and dry matter remobilization rate, and the positive and significant correlation between them, both Genotypes 952 and 953 are suitable for continuing research activity and introduce a new rice cultivar especially in drought and hot stress conditions at the grain filling stage. | ||
