N ielsen , E. L., and J. N ath . (U. Wisconsin, Madison.) Somatic instability in derivatives from Agroelymus turneri resembling Agropyron repens. Amer. Jour. Bot. 48(4): 345–349. Illus. 1961.—Variations in somatic chromosome numbers of 4 to over 80 were observed in root tip cells of Agropyron repens ‐like plants derived from Agroelymus turneri. The latter presumably had out‐crossed to Agropyron repens. Split spindles in dividing nuclei and multinucleate cells were observed in the root tip meristem. The nuclear and mitotic behaviors observed can perhaps be attributed to an unbalanced ribonucleoprotein system resulting from the combination of distantly related genomes in the formation of the hybrid.
