| چکیده | ||
| Micromorphological features regarding lower surface of leaf epidermis and seed surface in eight Crataegus taxa representing the series Pentagynae and series Crataegus subseries Erianthae were studied by scanning electron microscopy. All data were analyzed using Anova and PCA statistical methods. Qualitative traits of lower surface of leaf epidermis include relief of cuticle membrane, striations and kinds of crystalloid waxes allow distinct delimitation at infrageneric, inter- and infraspecific levels, whereas the quantitative characteristics are less informative. The seed traits compared to the leaf features provide less reliable characters in the taxonomy of the genus. | ||

| چکیده [English] | ||
| ویژگیهای ریز ریخت شناسی اپیدرم سطح زیرین برگ و سطح دانه در هشت تاگزون از جنس .Crataegus L مربوط به سری series Pentagynae وسری series Crataegus زیر سری subseries erianthae با استفاده از تصاویر الکترونی (SEM) مورد مطالعه قرار گرفت. تجزیه و تحلیل داده ها با استفاده از روشهای آماری تحلیل واریانس یکطرفه (ANOVA) و تحلیل مولفه های اصلی (PCA) انجام شد. صفات کیفی اپیدرم سطح زیرین برگ شامل تزیینات غشای کوتیکولی، نواره بندی و انواع واکسهای کریستالوئیدی در سطح زیر جنس، بین گونه ها و زیر گونه ها جدا کننده بودند در حالیکه صفات کیفی اهمیت کمتری داشتند. صفات مربوط به سطح دانه نیز اهمیت کمتری نسبت به صفات اپیدرم سطح زیرین برگ در تاگزونومی جنس دارند. | ||
