Sažetak
Development of glandular structures of xerophytes species Satureja montana L., Satureja cuneifolia Ten. and Satureja subspicata Vis., of Lamiaceae family, can be divided to pre-secretory, secretory and post-secretory stage of development. Plant materials were collected in sub-Mediterranean region of Croatia (Kozjak Mountain near Split). Conventional chemical fixation methods for Electron Microscopy were employed to examine the ultra structure of developing glandular trichomes of savory. Glands trichomes appear as epidermal foliar protuberances which divide asymmetrically to produce a basal cell, a stalk cell, and a cytoplasmically dense apical cell. Further divisions of the apical cell produce a glandular trichome with one basal cell, one stalk cell, and a twelve-cell head with subcuticular oil storage space. Presecretory gland cells resemble meristemic cells because they contain proplastids, small vacuoles and large nuclei. The secretory phase coincides with the intensive biosynthesis, separation and essential oil accumulation in sub-cuticular storage space. The ultrastructure of the post-secretory gland is fragile and tend to loose organizational integrity. Submicroscopic analyses of these cells showed well defined three-ply cell walls and the domination of plastids, mitochondria and endoplasmatic reticulum, all of them taking part in the metabolites production and transportation processes.
