The major research conclusions are summarized as follows: Naidong camellia cultivated in windbreak and shadow condition grow normally. As a result,the adaptability of Naidong camellia was evaluated to be the second degree,which means they could be adapted to Beijing and Tianjin areas. It is aslo observed that the drought soil,cold and dry wind and sunburning in winter and spring are the major factors affecting introduction of camellia.
