چکیده

به‌منظور دست‌یابی به کلن‌های پرمحصول و سازگار با شرایط آب‌وهوایی خرم‌‌آباد و معرفی آن‌ها برای کشت و تولید انبوه، 10 کلن صنوبر (Populus nigra L.) تاج‌بسته در قالب طرح آماری بلوک‌‌های کامل تصادفی با سه تکرار و فاصله کاشت ٣×٣ متر در ایستگاه باغ کشاورزی خرم‌آباد در یک دوره پنج‌ساله (1393-1389) ارزیابی شدند. نتایج تجزیه واریانس نشان داد که اثر عامل‌‌های سال و کلن بر صفات رویش جاری ارتفاع، رویش جاری قطر برابر سینه و رویش جاری حجم در هکتارمعنی‌‌دار بود. مقایسه میانگین‌ها نشان داد که بیشترین (2/05 متر) و کمترین رویش ارتفاعی (0/14 متر) به‌ترتیب به P. nigra 135/63 در سال چهارم آزمایش و P. nigra 48/56 در سال دوم آزمایش اختصاص داشت. همچنین، P. nigra 135/63 دارای بیشترین رویش قطر برابر سینه (2/57 سانتی‌‌متر) در سال پنجم و P. nigra 48/56 دارای کمترین رویش قطر برابر سینه (0/26 سانتی‌‌متر) در سال دوم آزمایش بودند. ‌‌P. nigra 135/63 و P. nigra 154/62 نیز در سال پنجم آزمایش به‌ترتیب بیشترین (7/17 متر مکعب در هکتار) و کمترین مقدار رویش جاری حجم (0/4 متر مکعب در هکتار) را داشتند. بررسی کیفی کلن‌‌های مختلف صنوبر نشان داد که به‌استثنای‌‌ P. nigra 72/56 و P. nigra 23/49 که به‌ترتیب دارای انحنای تنه کم و متوسط بودند، کلن‌‌های دیگر، تنه صاف و مستقیم داشتند.

چکیده [English]

    In order to identify the most productive and adaptable clones to local climate and introduce them to people for mass wood production, ten clones of Populus nigra L. were selected and were planted in Khorram Abad Agricultural Garden Station for five years (2010-2014). Variance analysis showed that the year and cologne factors had a significant impact on height, diameter, and volume increment. The result of mean comparisons showed that the highest (2.05 m) and lowest (0.14 m) of height increment were dedicated to P. nigra 63/135 clone in the fourth year and P. nigra 56/48 clone in the second year, respectively. Also the P. nigra 63/135 clone had the maximum diameter increment (2.57 cm) in the fifth year (2014) and P. nigra 56/48 clone had the minimum diameter increment in the second year. The P. nigra 63/135 and P. nigra 62/154 clones had the highest (7.18 cm) and lowest (0.4 cm) of volume increment in the fifth year, respectively. The qualitative study of different P. nigra clones showed that except for the P. nigra 56/72 and P. nigra 49/23clones which had low and moderate curved trunks, respectively, the other clones had smooth and straight trunks.
