For dendrochemical research, it may be important to aware of the effects stem asymmetry and intra-ring structure because these introduce unwanted dispersion in results. In studies, separate analysis elemental content early- latewood is rare. Also, explanations how relate originating from conditions at edges contrasting environments are largely lacking studies.
