A morphological and karyometric study of the secretory cells in mint
Morphological and karyometric peculiarities of oil-synthesizing secretory structures in mint forms differing by rate of oil biosynthesis were investigated. Significant similarity in morphology of secretory structures in investigated forms during differentiation and functioning was shown. Character of changes in karyometric properties of oil-synthesizing cells also was similar: nuclear and nucleolar volumes increased and then decreased during differentiation of secretory structures. A functional increase of nuclear and nucleolar volumes was found at the stage before essential oil secretion. Higher parameters at all stages of differentiation and before secretion were revealed in highly oil-production mint. This fact may serve as indirect indicator of increased functional activity of oil-synthesizing cells and intensity of oil-producing process. The obtained results are discussing with well-known data.
