Study on Morphological Adaptability of Phyllostachys pubescens Plantations to Coastal Area Environment

A comparative study on the mophological characteristics of the Phyllostachys pubescens plants grown in the coastal and inland plantations managed with similar measures was conducted in order to provide the scientific management of P. pubescens plantation in the coastal area and application of P. pubescens plantation to the construction of coastal shelterbelt system with theoretical basis. The results indicated that the indices of total bamboo height, under branch height, the bamboo wall thickness at D.B.H. and the relative height under the lowest branch of the coastal P. pubescens plantations were all significantly or extremely significantly higher than those of the inland P. pubescens plantation. Whereas the relative crown length and relative internode length of the coastal P. pubescens plantation were significantly smaller than those of the inland P. pubescens plantation. There were no significant differences in the D.B.H, relative total height, relative wall thickness at DBH, crown length, the number of nodes and the internode length betrween the coastal and inland P. pubescens plantations. The study explained that the coastal P. pubescens plantation was stronger in wind resistance than the inland P. pubescens plantation mainly because the former had relatively larger values of height under the lowest branches and smaller values of relative crown length and relative internode length in the crown.
