Abstract: In order to investigate the effects of water stress on the Carbohydrate Metabolism of the carrot storing organ and provide theory basement for culturing carrot in the water deficient area, the effects of water stress on fructose, glucose, sucrose and starch in carrot storing organ were studied with carrot cultivar "Xiangyang Ⅱ" (6 leaves). The results indicated that sucrose level significant decreased under water stress, the more water stress, the less sucrose. On the contrary, fructose and glucose level increased when water stress occurred. The tendency of starch content was same as that of sucrose (the change in xylem more than in phoem) change of starch in the xylem is more significant than in phloem.

Key words: Carrot, Water stress, Storing organ, Carbohydrate metabolism
