Abstract

In the present  study, Onosma discedens Hausskn. & Bornm., Onosma tenuiflora Willd., Onosma aucheriana DC., Onosma roussaei DC., Onosma rigida Ledeb. and Onosma trapezuntea Boiss. & A.Huet ex Hand.-Mazz. were examined by light microscopy (LM) in terms of stem and leaf anatomy. The anatomical characters were numerically analyzed by cluster analysis (CA) and principal component analysis (PCA). Although general stem and leaf anatomical traits are very similar, some anatomical characters such as the ratio of cortex/diameter of stem and phloem/xylem, the average row number of collenchyma, palisade and spongy cells, and stomata index are more important for delimiting the investigated taxa. These results indicated that anatomical features would be useful in separating the examined species.

Abstract [Persian]

در مطالعه حاضر گونه‌های زیر از نظر آناتومی ساقه و برگ با استفاده از میکروسکوپ نوری مورد بررسی قرار گرفته است.
Onosma discedens, Onosma tenuiflora, Onosma aucheriana, Onosma roussaei, Onosma rigida, Onosma trapezuntea.
 ویژگیهای آناتومی از طریق تجزیه خوشه‌ای و تجزیه به عامل‌ها مورد تجزیه و تحلیل قرار گرفته است. اگرچه ویژگیهای آناتومی عمومی ساقه و برگ گونه‌ها شبیه است، لیکن برخی ویژگیهای آناتومی مثل نسبت پوست به قطر ساقه و آوند آبکش به آوند چوبی، متوسط تعداد ردیف‌های سلولهای کلانشیمی، نردبانی و اسفنجی و همچنین شاخص روزنه‌ها اهمیت بیشتری برای تعیین حدود گونه‌های مورد بررسی دارند. . این نتایج نشان داد که ویژگی‌های آناتومی در جدا کردن گونه‌های مورد بررسی می تواند مفید باشد.
