Authors:Wang Xiaohong; Zhang Hong; Zhou Zuji

Abstract:Bamboo is not only an important forestry resource, but is also food for the Giant Panda in China. Wild bamboo typically flowers synchronously and gregariously and dies at the end of the event. Bamboo flowering is a serious problem in conservation of the endangered Panda. In order to find environmental factors that can influence bamboo flowering, a survey and analysis of climatic factors was undertaken in Yaan district in China, where bamboo flowered from 2001 to 2007. The result showed that both the average temperature in January and July in the FY (flowering years) were higher than that of NFY (non-flowering years), the annual precipitation in FY lower than that of NFY, and there were obvious drought years before bamboo flowering. The paper discusses the correlation between the climate factors and bamboo flowering based on the statistical analysis. The result showed that flowering had significant correlation with the average temperature in July and annual precipitation, high temperature in July and less precipitation contribute to bamboo flowering.
