petal micromorphology of some rosa species in iran

The micromorphological characteristics of the upper and lower epidermis of the petals of 15 rosa species in iran were investigated for the first time. the study used light microscopy (lm) and scanning electron microscopy (sem) to compare epidermal patterns of petals among different species. quantitative and qualitative characteristics related to the petals, including cell density, flower color, cell type, and stomata and trichomes on both surfaces, were compared between the rosa and hulthemia subgenera species in iran. no evidence of hairs and stomata was found on either surface of the epidermis. the arrangement of the adaxial surface in all species consists of conical cells called papillae with different degrees of projection and interconnected and a cuticle layer covers their surface. the abaxial surface pattern is often seen as flat cells with parallel lines or irregular folds. the cluster analysis using past software showed that, although the petal epidermis is a consistent feature within the species, this trait is unsuitable for classifying rosa species. in addition, in the present study it was found that, the difference in epidermal pattern in some species such as r. beggeriana and r. moschata was found to be useful to identify them from each other.
