STUDY REGARDING STOMATAL DENSITY IN MAGNOLIA SP.

The purpose of this study is to reveal the structural aspects of the leaf as occurring in the genus Magnolia. The leaves are bifacial and hypostomatic. Secretory oil cells are a constant presence. We have revealed significant dissimilarities in stomatal density and size as occurring in three ornamental species: Magnolia kobus, Magnolia x soulangeana "Soulange-Bodin" (M. denudata x M. liliiflora) and Magnolia x "Susan" (M. kobus var. stellata "Rosea" x M. liliiflora "Nigra"). The highest stomatal density was recorded in the diploid species Magnolia kobus. The stomata are significantly elongated in Magnolia x soulangeana "Soul.-Bod." and wide in Magnolia kobus.
