Temporal variations of biomass, carbon and nitrogen of roots under different tree species

Abstract

Seasonal changes of root biomass, concentrations and masses of carbon and nitrogen in roots and root diameter classes (5mm) were evaluated under four adjacent coniferous plantation sites: Oriental spruce (Picea orientalis L.), Austrian pine (Pinus nigra Arnold), Turkish fir (Abies bornmulleriana L.), Scots pine (Pinus sylvestris L.) and natural Sessile oak (Quercus petraea L.) forest.
