Investigation of foliar morphological features of Salvia greggii leaf


Parui Mondal and Sanjukta Mondal

Foliar micromorphology of Salvia greggii A. Gray was investigated using the scanning electron microscope (SEM). The leaves were characterized by anisocytic stomata which were more abundant on the abaxial epidermal surface. Short multicellular glandular trichomes were observed on both leaf surfaces. Uniseriate and multicelullar non glandular trichomes were also found but more abundant over the mid-rib. Crystal deposits were observed on the epidermal surfaces. Energy dispersive X-ray spectroscopy-SEM of the crystals showed Na, Cl, Ca, Cd, Zn, Mo, Pb, Pi, Si, and S to be the major components. These elements are very essential for plant growth. Glandular and non glandular trichome stability can be attributed to the presence of these elements in this species.
