چکیده

بلوط ایرانی (Quercus brantii) یکی از گونه‌های اصلی جنگل‌های‎ زاگرس است که از اهمیت ویژه‎ای برخوردار است. ارزیابی جوامع مختلف این گونه به‎منظور شناسایی پایه‎های برتر و تجزیه روند رشد در نهال‌های به‌دست آمده از این پایه‌ها از اهداف این پژوهش بود. از 12 پایه سالم در یک جمعیت بلوط ایرانی واقع در استان لرستان بذرگیری شد و در قالب طرح آماری آشیانه‌ای با سه تکرار آزمون نتاج انجام شد. علاوه‌بر تجزیه بیومتریکی و ژنتیکی داده‌های به‌دست آمده از ویژگی‌های ریخت‌شناسی، روند تغییرات رفتارهای رویشی طی دو سال در بین خانواده‌های ناتنی مورد نظر بررسی شد. درختان مادری از نظر همه ویژگی‎های مورد مطالعه تفاوت معنی‌داری از خود نشان دادند. ضمن برتری مطلق نتاج یکی از پایه‌های مورد بررسی که از نظر بیشتر صفات فاصله زیادی با بقیه داشت، روند رشد در سال دوم در 340 نهالی که از این 12 خانواده مطالعه شد، مشابه روند رشد سال اول بود. ضمن اینکه، خانواده‎هایی که از نظر ارتفاع نهال، قطر یقه و تعداد برگ در سال اول رتبه‌های بالا را کسب کرده بودند، در سال دوم نرخ رشد بهتری داشتند. به‎عبارت دیگر، گزینش پایه‌های برتر بر اساس آزمون نتاج و در مرحله نونهالی می‌تواند به‌طور مؤثر مبنای انتخاب پایه‌های برتر برای استفاده در اهداف اصلاحی ازجمله تشکیل باغ بذر قرار گیرد. وراثت‌پذیری صفات مورد مطالعه در سال دوم رویش بین 48/0 تا 99/0 متغیر بود و همبستگی بیشتر صفات در سال دوم تقویت شد.

چکیده [English]

Brant`s oak (Quercus brantii Lindl.) is one of the most important tree species of Zagros forests. The major objective of the study was to assess various populations of the species for identification of plus tree individuals and growth trend analysis of the sapling of the selected trees. Therefore, seeds were collected from twelve single trees of one Brant`s oak populations located in Lorestan province. The selected trees were progeny tested based on a nested statistical design with three replications. Morphological data were biometrically and genetically analyzed, followed by investigating the trend of growth changes during the two years of the study. The selected trees were significantly different in the studied attributes. In addition, one of the progeny families showed outstanding domination over the others. Second year growth trend of 340 studied progeny saplings of the twelve families was similar to that of the first year. Meanwhile, the families with higher rank for the first-year growth based on seedling height, collar diameter and leaf number obtained better growth rates during the second year of the experiment. In other words, selecting plus trees based on progeny test at early years of sapling growth may effectively be used for selecting plus trees for breeding purposes such as seed orchard establishment. Furthermore, heritability of the studied characteristics varied between 0.48 to 0.99 and correlation coefficients between most of the paired characters increased for the second year.
