Abstract
The influences of succession and species diversity on fine root production are not well known in forests This study aimed to investigate i whether fine root biomass and production increased with successional stage and increasing tree species diversity ii how forest type affected seasonal variation and regrowth of fine rootsFine root biomass increased from 262 g·m−2 to 626 g·m−2 with increasing successional stage and species diversity A similar trend was also found for fine root production which increased from 86 to 114 g·m−2 yr −1 for Cunninghamia lanceolata plantation to 211–240 g·m−2 yr −1 for Choerospondias axillaries forest when estimated with sequential coring data Fine root production calculated using the ingrowth core data ranged from 186 g·m−2 yr −1 for C lanceolata plantation to 513 g·m−2 yr −1 for Lithocarpus glaber – Cyclobalanopsis glauca forestThis study was financially supported by the National Natural Science Foundation of China 31170426 and 30771720 the New Century Excellent Talents program NCET060715 the Program for Science and Technology Innovative Research Team in Higher Educational Institutions and the Furong Scholar Program of Hunan Province
