| چکیده | ||
| قارچها یکی از اجزای مهم و اصلی در اکوسیستمهای جنگلی میباشند که نقش مهمی در فرایند تبدیل و بازگشت عناصر معدنی به خاک، چرخه مواد و حاصلخیزی رویشگاه جنگلی بر عهده دارند. به‌منظور بررسی و شناسایی قارچهای ماکروسکوپی درختان راش و ارتباط آنها با عوامل فیزیوگرافی (ارتفاع از سطح دریا، شیب، جهت دامنه) نمونهبرداری در فصول زمستان و بهار بعد از انجام جنگلگردشیهای مقدماتی، طی چندین برداشت در جنگل خیرود نوشهر در قطعه‌های 112 پاتم و 212 نمخانه از کلیه درختان راش آلوده به قارچ، آماربرداری صددرصد انجام شد. طی این برداشتها 75 نمونه قارچ ماکروسکوپی از روی درختان راش مناطق مورد مطالعه جمعآوری گردید که 36 نمونه مربوط به قارچهای عامل پوسیدگی چوب بود. ارتباط فراوانی قارچهای ماکروسکوپی درختان راش با عوامل فیزیوگرافی در محیط آماری SAS محاسبه گردید و اختلاف معنیدار بودن حضور آنها بر اساس جدول تجزیه واریانس در قالب آزمایش فاکتوریل پس از اطمینان از نرمال بودن دادهها با آزمون دانکن تعیین شد. نتایج این تحقیق نشان داد که فراوانی قارچها در طبقات مختلف شیب و ارتفاع از سطح دریا و همچنین در جهتهای مختلف دامنه در سطح اطمینان 99 درصد دارای اختلاف معنیدار بودند، به‌طوری‌که بیشترین فراوانی قارچهای ماکروسکوپی چوبزی به‌ترتیب در ارتفاع بین 870 تا 970 متر از سطح دریا، شیب 0 تا 20 درصد و در جهت شمالی میباشد. | ||

| چکیده [English] | ||
| Fungi are one of the major components in forest ecosystems and play an important role in converting processes as well as soil nutrients recycling and forest site fertility. The aim of this research was to identify beech macroscopic fungi and their associations with physiographic factors include altitude, slope and slop direction. Following winter and spring field surveys in parcels 112, 212 of Kheyroud forest, fungi samples associated with affected beech trees were collected. Totally 75 samples of macro fungi were collected of which 36 samples belong to wood-rotting y fungi. SAS statistical software was used to investigate any correlation between fungi abundance on beech trees and the physiographic parameters and The Duncan test was conducted to evaluate the differences. Results showed significant correlation between the physiographical factors and abundance of fungi (p<0.01). The highest macro fungi abundance was found in altitude of 870-970 m, 0 to 20 percent slope and in the Northern direction. | ||
