The key technology for biomass production of woody species is propagation via micropropagation. Development of in vitro culture techniques has made it possible to commercially propagate useful trees, both forest and fruit trees. In this book comprehensive information is provided on micropropagation of economically important forest and fruit trees, which is usually available in scattered literature. Topics cover a wide range, from tropical forest and fruit trees for paper or food supply, to Prunus species for local craft bark production. Micropropagation of fagus, eucalyptus, acacia, aegle and fruit trees such as grapevine, bananas, apples, avocado, papaya, pistachio, olive, kiwifruit, litchi, and tea is described. General subjects on light quality, arbuscular mycorrhizal fungi, pathogen elimination, molecular markers, bioreactor, photoautotrophism, thin cell layer and in vitro germplasm conservation are also described.
