چکیده

در فصل رویشی سال‌های 1385 و 1386، با استفاده از روش‌های تجزیه چند متغیره، تفاوت‌های ریخت‌شناسی جمعیت‌های پیچک‌صحرایی در استان تهران مورد بررسی قرار گرفت. برای تعیین این تفاوت‌ها، 43 صفت ریخت‌شناسی و فیزیولوژیکی بررسی بیومتریکی شدند. مهم‌ترین صفات مؤثر در تجزیه صفات به مؤلفه‌های اصلی (PCA) برای تمایز بیوتیپ‌ها، وزن خشک برگ، وزن خشک اندام‌ هوایی و سطح برگ بودند. اما برای تمایز جمعیت‌ها، صفات آلومتریک بویژه نسبت وزن خشک ریشه معیار قرار گرفتند. نتایج نشان داد که اکوتیپ‌های پیچک‌صحرایی در اثر سازش با محل جغرافیایی خود بوجود آمده‌اند. تغییرات در فنولوژی و ریخت‌شناسی بیوتیپ‌های پیچک‌صحرایی ممکن است گویای ماندگاری و سازش یک جمعیت از این علف‌هرز بر حسب تغییرات شرایط‌محیطی و روش‌های مدیریت آن باشد.

چکیده [English]

Morphophysiological variations of field bindweed populations in Tehran province was studied during 2006 and 2007 growing seasons using multivariate analysis methods. To determine the variations, 43 morphological and physiological characters were considered biometrically.  The main characters at principal component analysis (PCA) consisted of leaf dry weight, shoot dry weight, and leaf area to identify the biotypes. But, the populations were identified based on allometric variables, particularly root weight ratio. The results suggested that field bindweed ecotypes have been formed while the species adapted to specific geographic locations. Factor analysis based on PCA revealed that twelve factors comprise almost 85% of total variations for field bindweed populations in three locations of Tehran province. Phenological and morphological variabilities among biotypes may explain the survival and adaptability of a population of this weed as a result of environmental and field management changes
