摘要：

The uptake of nitrate, sulphate, phosphate, and potassium from a nutrient solution by young alder trees (Alnus glutinosa) was reduced during hypoxia. Such a decrease of ion uptake was not observed when the internal oxygen supply of the tree roots was improved by pressurized gas transport. These results demonstrate the beneficial effect of this gas transport phenomenon on the nutrition of trees growing on wet sites characterized by anaerobic soil.
