基　　金：support by the UK Department of Environment, Food and Rural Affairs (Project no.NF0424) for willow breeding from 2003-2010 and from the UK Biotechnology and Biological Sciences Research Council (BBSRC) Institute Strategic Programme Grant for Rothamsted Research's Centre for Bioenergy and Climate Change;BBSRC also provides the funding support for the BBSRC Sustainable Bioenergy Centre (BSBEC-Bio-MASS) and EraNet projects referred to in the article 摘　　要：Willows (Salix spp.) are a very diverse group of catkin-bearing trees and shrubs that are widely distributed across temperate regions of the globe.Some species respond well to being grown in short rotation coppice (SRC) cycles,which are much shorter than conventional forestry.Coppicing reinvigorates growth and the biomass rapidly accumulated can be used as a source of renewable carbon for bioenergy and biofuels.As SRC willows re-distribute nutrients during the perennial cycle they require only minimal nitrogen fertilizer for growth.This results in fuel chains with potentially high greenhouse gas reductions.To exploit their potential for renewable energy,willows need to be kept free of pests and diseases and yields need to be improved without significantly increasing the requirements for fertilizers and water.The biomass composition needs to be optimized for different end-uses.Yields also need to be sustainable on land less productive for food crops to reduce conflicts over land use.Advances in understanding the physiology and growth of willow,and in the identification of genes underlying key traits,are now at the stage where they can start to be used in breeding programs to help achieve these goals. 关键词：生物燃料生物能源遗传改良柳树可再生能源温室气体减排土地使用持续生产力
