Abstract: Xiangyang No.2 potted plant was used to study affecting carrot growth under various degrees of water stress and after freed from water stress. The results showed that canot growth was largely affeded by water stress, when being seriously short of water, the leaves growth and roots growth were distinctly restrained. Seedirg growth amount, dry matter accumulation and water content were effectively decreased. These targets were dffficultly recovered even though removed water stress. Water stress could large affected on cell structure of leaf, with enhanced degree of water stress, the karyon amount decreased, and the nucleolus reduced, distorted or degraded. As were difficultly recovered after removed water stress.

Key words: Carrot, Water stress, Relief stress, Growth, Cell structure
