Biomass increment data - measured										
remarks:	data from Matteucci et al. (2000); method: Scarascia-Mugnozza et al (2000)									
	increment of branches obtained form the increment of branches basal area on a sample of ca. 80 branches									
	increment of roots calculated on the basis of root diameter increment									
	increment twig based on the ratio of  dry weight of 1 yr-old twigs to leaf dry weight of ca. 80 branches									
	increment stump calculated on the basis of the increment of circular area measured at the base of the stems
