| Abstract: | Principal component analysis was used to study and evaluate the geographical provenances of Dendrocalamus latiflorus in two pilot fields. Excellent provenances were selected according to different management purposes and different conditions of afforestation areas. The results showed that real gains of the selected provenances were significant. The average real gains of main characteristics of four selected provenances for bamboo shoots were between 1.19% and 32.46% ; those of four selected timber-use provenances were between 4.11% and 39.7%.
