SEASONAL DYNAMICS OF FLAVONOID ACCUMULATION IN THE DIFFERENT SPECIES OF RHODODENDRON L. AS MARKERS OF ACCLIMATION RESPONSES
Quantitative flavonoids in Rhododendron L. species content during vegetative period is analyzed. There was found a quantitative dependence of flavonoids content upon the plant ontogenesis phase. The dynamics of flavonoids content is considered to be an indicator of acclimation ability of rhododendron species during their introduction.
