Abstract:

Climate change is a global political,economic and social hot topic,and coping with climate change is an important mission for Chinese forestry. A clear understanding of the factors that influence wood cell structure is indispensable to the scientific support for Chinese forestry and the research of wood cell structure on response to climate change. In this paper the studies of wood cell structures,such as intra-annual tracheid numbers,dimensions and wall thickness and numbers of resin ducts in softwoods,and vessel numbers and dimensions in hardwoods,on responses to temperature and precipitation were reviewed. In the meantime,some non-climate influences on wood cell structure,such as terrain,soil,altitude, latitude,air pollution, insects,disease,planting density, fertilization and irrigation were discussed in the paper.

Key words: tracheid, vessel, temperature, precipitation, non-climate factor, climate change
