Authors
Abstract:
بومادران( Achillea L.) یکی از مهم ترین جنس های دارویی تیره مرکبان ( Asteraceae ) است که درنقاط مختلف جهان پراکنش دارد. بومادران هزاربرگ (Achillea millefolium) یکی ازگونه های این جنس است که دارای تنوع فنوتیپی وژنوتیپی زیادی درایران است.آنالیز سیتولوژیکی سه ژنوتیپ این گونه مربوط به سه استان مختلف کشور به منظور دستیابی به سیتوتیپ های جدید انجام شد. نشان ویژگی های کروموزومی وتقارن کاریوتیپی حاکی از آن است که دوجمعیت دارای 2n=6x=54 کروموزوم وهگزاپلویید است.جمعیت مربوط به استان تهران 2n=8x=72 کروموزوم واکتاپلویید می باشد. جمعیت Am4 متقارن ترین کاریوتیپ راداراست. براساس نتایج حاصل تغییرات ساختاری کروموزومی وتغییر شرایط اکولوژیکی نقش مهمی درتنوع درون گونه ای این تاکسون دارا می باشد.
