Abstract:Specific leaf weight, photosynthetic rate, photorespiration rate, as well as N, P, K contents were measured in the leaves of Dendrocalamopsis vario-striata grown in Chishan Forest Farm in Fujian Province during shoot development. Results indicated that specific leaf weight (SLW) was higher at shoot abundant stage (in mid July) than that at early stage (on 12, June) and late stage (on 10, September). SLW decreased as the bamboo age increased, and increased with the ascending levels of leaf location on bamboo stems． Net photosyn thetic rate at shoot abundant stage was higher than that at early stage．whereas photorespiration rate and dark respiration rate were higher at early stage．The contents of N，P and K in bamboo leaves decreased gradually during shooting period．N content in leaves was in the order of 1-year-old>2-year-old>3-year-old bamboo, and being the highest in leaves on mid part of bamboo stems， whereas the contents of P and K decreased with the ascending levels of leaves on stems，an d increased with the increase of the bamboo age．The results would provide guidance for scientific management of D．vario-striata plan ting.
