Ecology of Alnus Glutinosa (L.) Gaertn: IV. Root System. McVean, D. N.
abstract   bibtex   
Analysis of the gas contained in alder roots from below soil water-table is described and the results shown to be comparable with those obtained by other workers on the submerged parts of herbaceous aquatics. The gas is largely contained in the xylem elements as in the genus Aeschynomene. The structure of the water lenticels on stems, roots and nodules is described and the suggestion made that they may play an important part in the root aeration mechanism of the species when growing on waterlogged sites. Root-cutting experiments to test the importance of different parts of the root system in the water supply of the tree have shown that the deep tap roots may well account for the success of the established alder on sites of deep water-table. The importance of the surface system (with its nodules and mycorrhiza) in the nutrition of the tree on infertile soils was also demonstrated by this method.
