چکیده

شناخت خصوصیات فنولوژی گیاه نیمه‌انگلی موخور (Loranthus europaeus Jacq.)گامی اساسی برای مدیریت کنترل آن در زمان مناسب است. برای این منظور جنگل‌های بلوط دامنه جنوبی کوه مانشت واقع در میان‌تنگ هیانان در شمال شرقی شهر ایلام انتخاب شد. در منطقه مورد مطالعه سه منطقه تحقیقاتی در ارتفاعات 1600 تا 1800، 1800 تا 2000 و 2000 تا 2200 متر از سطح دریا درنظر گرفته شد. در هر منطقه پنج درخت بلوط ایرانی مبتلا به موخور گزینش شدند و پایش صفات فنولوژی آنها طی پنج سال انجام شد. نتایج نشان داد که صفات فنولوژی موخور متأثر از موقعیت ارتفاعی بود. پدیده‌های فنولوژیک در ارتفاعات پایین با اختلاف چندروز زودتر از ارتفاعات بالاتر رخ داد. همچنین زمان ظهور پدیده‌های فنولوژیک و بازه زمانی آن‌ها در سال‌های متوالی با هم تفاوت داشت. براساس نتایج ظهور پدیده‌های فنولوژیک در ارتفاعات مختلف و سال‌های مختلف، می‌توان گفت که زمان پیش از رسیدن میوه که تا مردادماه است، مناسب‌ترین زمان برای قطع موخور است. در صورت توجه به زمان مناسب قطع، می‌توان پیش از رسیدن میوه موخور به حذف مطمئن کپه‌های موخور از روی درختان بلوط ایرانی کمک کرد و از بروز مشکلات جمع‌آوری و حذف میوه‌های موخور و احتمال پراکنش بعدی بذرها جلوگیری کرد.

چکیده [English]

Understanding the phenological characteristics of the semi-parasitic continental mistletoe (Loranthus europaeus Jacq.) is an essential step for a timely control management of its expansion. To this aim, a portion of oak stands of the southern slope of the Manesht mountain located in Hyanan region in the North East of Ilam was investigated. Three test sites located in altitudes of 1800-1600, 2000-1800 and 2200-2000 m above sea level were considered, in each of which five mistletoe-infested Persian oak trees were selected. The phenological traits were monitored over five years. The results showed that phenological traits are affected by elevation, i.e. the phenological events at lower altitudes occur a few days earlier than the higher elevations. In addition, the appearance time of phenological events was different during successive years. According to the results of our phenological analysis at different altitudes and in different years, it is concluded that the optimal time span for removing mistletoe is prior to its fruit ripening until August. In order to avoid the problems of collecting and dispersing of mistletoes seeds, we can remove the mistletoes on the Brant`s oak trees before the ripening of fruits in the proper time of cutting.
