This experiment was designed to examine the content of water, carbohydrate, minerals, phenols, ABA, and ethylene in fruit trees as affected by flooding. Young fruit plants were grown and tested in the pot under plastic house. The results are as follows.
1. Foliar moisture content showed decreasing tendency by flooding, especially remarkable in Prunus species.
2. The carbohydrate content was severely decreased by flooding.
3. Mineral content in leaves showed a decreasing tendency in all flooded fruit trees except Prunus species.
4. An increase in root phenolic compounds was noted only in apples, while no significant changes were noticed in pears, peaches, and grapes.
5. The flooded young fruit plants produced more ethylene in leaves and ABA in shoots as compared with unflooded plants.
