چکیده

هدف این پژوهش تعیین ارتباط برخی عوامل فیزیوگرافی (جهت، شیب و ارتفاع) و مشخصه­های درختان دانه‌زاد بلوط ایرانی شامل ارتفاع، قطر برابرسینه و قطر تاج با مقدار زی‌توده ریشه­های مویین در جنگل هشتادپهلو-لرستان است. بدین منظور در امتداد دامنه­های جنگل، درختان سالم بلوط به روش تصادفی انتخاب و در زیر تاج و در جهت شمالی و جنوبی آنها نمونه­برداری از عمق صفر-15 و 15-30 سانتی­متری خاک انجام و سپس زی‌توده و کربن ریشه­های مویین اندازه­گیری شد. نتایج تجزیه واریانس و آزمون t مستقل به­ترتیب برای عامل جهت و ارتفاع نشان داد که این عوامل بر مقدار زی‌توده ریشه­های مویین درختان بلوط مؤثر بوده و بیشترین مقدار زی‌توده در جهت غربی و ارتفاع 1870-1670 متر از سطح دریا مشاهده شد (01/0>P). در رویشگاه نتایج تجزیه واریانس نشان داد که عامل شیب بر مقدار زی‌توده ریشه­های مویین درختان بلوط تأثیر­گذار نیست و ضرایب همبستگی پیرسون نشان داد با افزایش ارتفاع و قطر برابرسینه درختان بلوط مقدار زی‌توده و کربن موجود ریشه­های مویین آنها کاهش می­یابد (05/0>P).

چکیده [English]

The objective of the present research was to study the effect of some physiographical factors (Aspect, slope, elevation) and features of Persian oak (Quercus brantii Var. persica( including height, DBH and crown diameter on fine root biomass in Hashtad- Pahlu forest, Lorestan. For this purpose, fine roots of oak trees were sampled randomly at   soil depths of 0-15 and 15-30cm in north and south positions under canopy of trees, then the amount of biomass and carbon were measured in laboratory. Analysis of variance and independent t test results showed that aspect and altitude had influences on fine root biomass so the highest amount was observed in the west aspect and the altitude of 1670-1870 m a.s.l )p<0.01(. The slope factor had no effect on the root biomass of trees in the site, as well Pearson’s correlation indicated that with increasing height and DBH of trees, biomass and carbon content were decreased )p<0.05(.
