Summary

In field trials in 1961-2 the crowns and roots of the winter-hardy lucerne cv. Vernal contained greater quantities of water-soluble trichloroacetic-acid-precipi-table protein and nucleic acids than the non-hardy cv. Caliverde during the development and maintenance of cold hardiness. The relationship between each of these constituents and cold hardiness was closer for the hardy than for the non-hardy cv. Seasonal trends in cold hardiness, content of water-soluble trichloro-acetic-acid-precipitable protein and content of nucleic acids were markedly different for the 2 cv. In response to changing environmental conditions in the autumn, varietal differences were first noted for the DNA content, then for RNA and finally for the water-soluble trichloroacetic-acid-precipitable protein content and cold hardiness. Tissue pH appeared to be positively related to cold hardiness.
