Abstract

Abstract: Camellia oleifera is a unique woody edible oil tree in China. In recent years,China is making huge efforts to improve the self-sufficiency of cooking oil. Though regarded as a drought-resistant plant,C. oleifera is mainly cultivated in hilly lands of southern China,however,the serious water shortage and drought environment are still the major obstacles of limiting C. oleifera growth. This paper reviewed the the morphological indexes,yeld and quality,osmotic adjustment substances,protective enzymes,photosynthetic characteristics and chlorophyll fluorescence,and molecular level of C. oleifera under drought stress. We also discussed the current issues and the focuses in the future studying the drought stress of C.oleifera. In order to provide some suggestions for the research of drought resistance mechanism,drought resistant cultivation and drought resistance breeding in C. oleifera.

Key words: Camellia oleifera, drought stress, morphological indexes, physiological indexes, molecular level
