Anatomical and micromorphological studies on leaves of salvia l. species in ne iran

This study has examined anatomical and micromorphological characters of leaves of 10 Salvia species growing in the north east of Iran. For anatomical study, the matured dry leaves were selected and fixed in FAA solution. Manual cross sections of the leaves were prepared and stained by differential staining. For leaves micromorphological study, the epidermal cells and trichomes were noticed by SEM. Some differences were perceived in the shape of midribs outline, the number of collenchymous and parenchymous cell layers and the shape of sclerenchymous tissue above the phloem in the midrib. As to the leaves micromorphological findings, the differences between the shape of trichomes on the leaves surface were observed. According to the results, the shape of midribs outline were recognizable between the studied species.
