H anson , C. H. (U.S.D.A., Beltsville, Md.), W. A. C ope and R. M. B rinkley . Chemical changes in Lespedeza associated with induced polyploidy. Amer. Jour. Bot. 46(1): 36‐39. 1959.— Changes in the quantities of 5 chemical constituents which were associated with induced polyploidy were studied using leaves of the following polyploids: Autotetraploids— Lespedeza cuneata, L. latissima, L. stipulacea , and L. striata; amphidiploids— L. hedysaroides × L. cuneata and L. latissima × L. cuneata. L. stipulacea and L. striata were annuals with low concentrations of tannin; the other species were perennials and high in tannin content. The polyploids were generally lower in crude protein, P 2 O 5 , and CaO, and higher in K 2 O and total tannin. The greatest and most significant shift was in total tannin. Induced polyploids of Lespedeza did not appear promising as forage plants.
