摘要：

The effect of water stress on cytokinin and ABA content was studied by immunoassay in durum wheat seedlings. Water deficiency was caused by submerging the roots in a polyethylene glycol (PEG) solution. Within two days after the treatment, PEG induced a considerable increase in root ABA content. Water stress initially decreased zeatin and zeatin riboside contents in both shoots and roots; however, by the third day, the level of cytokinins was restored. The importance of the changes in cytokinin concentration for plant adaptation to water stress is discussed.
