The nodules are peren-nial and increase in size each year, eventually becoming over an inch in diameter. In some plants, such as alder, the individual lobes that make up the nodule are very tight and compact. In others, such as sweet fern, each lobe of nodule grows out into an upwardly growmg root creating a sort of witch’s broom effect. These nodules

That leads me to this question: since there are really no fungi in the soil and since the alder is a colonizing species, where does the fungi come from? Virtanen (1957) showed that when spruce was planted beside alder, it obtained N fixed in the root nodules of the alder. He calculated that, in a grove of alders about 2.5 m high and with 10,000 trees per hectare, the leaf fall and roots remaining in the soil would add about 200 kg ha –1 of N. Nitrogen losses were not considered in the Bacteria in their root nodules move nitrogen from the air into the soil, making it available to the tree and nearby plants. For this reason, alders can more readily colonize disturbed, nitrogen-poor landscapes than other trees that lack this adaptation, and are valuable for restoration projects. Speckled alder is used locally for fuel but the wood has no commercial value. Because root nodules of alders support nitrogen-fixing bacteria, yields of timber-producing trees can be enhanced when grown in association with alder, in the same way that leguminous crops increase production in agricultural crops. Root nodules present on alder and few other groups of woody plants contain Frankia.

It has been shown that nitrogenase activity is correlated with on alder vegetation phases and seasonal Citrulline is shown to be the predominant free amino acid in alder root nodules, while serine also occurs in relatively large amounts. Citrulline and glutamic acid are prominent free amino acids in alder xylem tissue. The activities of N 2 ‐ase, GS, GDH, and OCT in root nodule homogenates are reported.

3: The image on the left shows excavated roots from a living alder tree ( Alnus rubra ). There are many yellow-orange nodules in clusters on the roots where Frankia is actively fixing nitrogen. 2009-11-1 The root nodules of alder are capable of producing nitrogen. It helps in increasing the fertility of the soil.

Of 46 Alnus incana subsp. rugosa nodules prepared, 42 yielded isolates. A simple medium containing mineral salts, Casamino Acids, and sodium pyruvate proved to be the most effective for isolation. In general, colonies appeared 6 to 20 days after inoculation.
