A new ideology for direct auxanometric measurements is proposed, which allows to analyze growth dynamics at different developmental stages. The above measurements include long-term monitoring using optical analysis with direct mass spectroscopic and gas chromatographic detection. Based on the known flavor differences of blooming plants at various phenological stages, we propose to distinguish phenological stage dynamics of various plant species and groups according to modern trends in flavor chemistry. It is possible to perform a simultaneous chemical analysis and automatic classification of forest plants in model plant communities according to their phenorhythm types and phenological groups with the approach described using automatic pattern recognition and fingerprinting. The novel method can also provide phenospectral data ranging useful for establishing the dependence of plant growth and developmental stage phenology on the environmental factors. Since the method is based on combination of several different measurement sources, it possesses a wide application in laboratory climatic chambers as well as in natural field conditions with the equipment placed in meteorological nets.
