Abstract

Net photosynthetic rate (Pn) increased in bamboo (Phyllostachy pubescens) with increased atmospheric CO2 concentrations. Average maximum Pn was 17.76, 16.66, and 16.77 (μmol/m2/s) in lower, middle and upper layers canopy respectively at CO2 saturation point. Light use efficiency of leaves ranged from 0.15% to 2.25% on different days and at different times of year measured by LP-6400 at 900 m altitude in the Tianmu Mountain Natural Reserve (TMNR) in Northwest Zhejiang Province, China. At two distant locations (TMNR and Lingfeng Bamboo Farm, Anji County) annual radiation conversion efficiency was 1.43% and 1.62% into total biomass (ET), and 0–1% into harvestable biomass (Eh). Carbon sequestration rates were 14.8, and 16.7 t/ha/annum at the two locations. We argue that expansion of bamboo forests into marginal lands of China, with improved management, offers real potential and options to counter climate change. Copyright © 2011 The New York Botanical Garden.
