Abstract: Under the conditions of field and greenhouse, the influence of temperature, water supply and illumination on shooting, growth and abnormal culm rate was investigated. The results showed that temperature had no influence on shooting number per cluster, new culm number per cluster and abnormal culm rate under adaptive temperature. With the increase of temperature, shooting time was brought forward and shooting period was extended. Water supply had obvious influence on shooting time and shooting period. Shooting number per cluster and new culm number per cluster were increased with the water supply interval shortened, while abnormal culm rate was decreased obviously. Shooting time was brought forward, and shooting number per cluster, new culm number per cluster and abnormal culm rate were increased along with the increase of illumination, while no influence was found for illumination on shooting period. It is concluded that water supply and illumination were the principal environmental factors for shooting, growth and abnormal culm rate of Bambusa ventricosa.
