摘要
油茶(Camellia oleifera Abel.)是中国特有的木本油料作物。近年来,国家大力提高食用油的自给率,油茶作为一种主推的木本油料作物,种植面积不断加大。油茶虽然其被归为耐旱树种,但其主要栽培于南方丘陵山地,极端缺水的干旱环境仍然成为限制油茶生产的主要障碍。综述了干旱胁迫下油茶形态指标、产量品质、渗调物质、保护酶系统、光合荧光及分子水平等方面的变化,在此基础上讨论了当前针对油茶干旱胁迫研究存在的问题和困境,并提出未来的展望,以期为油茶抗旱机制、抗旱栽培、抗旱育种等研究提供参考。
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.
