| چکیده | ||
| این پژوهش به منظور مقایسه عملکرد علوفه و شاخص سطح برگ ژنوتیپ‌های مختلف یونجه طی دو سال و برآورد شاخص سطح برگ از طریق وزن برگ و ارتفاع بوته طی سال‌های ۱۳۹۰ و 1391 به اجرا درآمد. در این آزمایش 20 ژنوتیپ داخلی (سردسیری و گرمسیری) و خارجی یونجه در سه تکرار در قالب طرح بلوک‌های کامل تصادفی در بهار سال 1390 در مزرعه مؤسسه تحقیقات اصلاح و تهیه نهال و بذر کرج کاشته شد. نتایج تجزیه واریانس دو ساله عملکرد علوفه تر و خشک بیانگر تفاوت معنی‌دار بین میانگین ژنوتیپ ها بود. ژنوتیپ‌های Bami ×Yazdi، Mesa sersa و KFA17 به ترتیب با 99/41، 84/39 و 15/39 تن در هکتار علوفه تر و 75/9، 41/9 و 16/9 تن در هکتار علوفه خشک بیشترین عملکرد علوفه را دارا بودند. علیرغم تفاوت معنی‌دار بین ژنوتیپ‌ها از نظر نسبت برگ به ساقه، تفاوت معنی‌داری بین میانگین ژنوتیپ‌های مورد بررسی از نظر شاخص سطح برگ مشاهده نشد. نتایج نشان داد که امکان برآورد سریع، دقیق و کم‌هزینه شاخص سطح برگ از طریق صفات وزن برگ و ارتفاع بوته میسر می‌باشد. در این بررسی، صفت وزن برگ (بویژه وزن تر برگ) نسبت به ارتفاع بوته کارآیی بیشتری در برآورد شاخص سطح برگ از طریق یک مدل خطی (بدون ثابت) با ضریب تبیین بالا (94/0R2 ≥) داشت. چنین نتیجه گرفته شد که در گیاه یونجه هر 100 گرم وزن برگ تر 35/0 متر مربع، هر 100 گرم وزن برگ خشک 51/1 متر مربع و هر 10 سانتی‌متر ارتفاع معادل 25/0 متر مربع سطح برگ دارا می‌باشند. | ||

| چکیده [English] | ||
| This study was executed to compare forage yield and leaf area index of different alfalfa genotypes for two years and also, to estimate of LAI via leaf weight and plant height during 2011 and 2012. Twenty local and forigen alfalfa genotypes were planted in a RCB design with three replications in spring, 2011 at Seed and Plant Research Institute (SPII), Karaj, Iran. Two-years analysis of variance indicated significant diferent among genotype's means for fresh and dry forage yield in which Bami x Yazdi, Mesa sersa and KFA17 genotypes with 41.99, 39.84 and 39.15 (t ha-1) fresh forage yield and 9.75, 9.41 and 9.16 (t ha-1) dry forage yield were the most forage production, respectively. Despite the significanat difference among genotypes for leaf to stem ratio, there was no significance difference for LAI. The results showed that the fast, accurate and low-cost estimation of LAI is possible through leaf weight and plant height. In this study, leaf weight trait (especially the fresh leaf weight) had more efficiency than plant height in estimating leaf area index through a linear model (without constant) with high coefficient of determination (R2 ≥ 94). It was resulted that every 100 gr of fresh and dry leaf and 10 cm of plant height of alfalfa had 0.33, 1.51 and 0.25 m2 leaf area, respectively. | ||
