Abstract
PREPARATIONS rich in vitamin C made from the flesh of ripe Rosa receptacles are now being produced on an industrial scale, in Sweden as well as in other countries. The systematic examination of native and cultivated species of Rosa has shown that considerable differences occur in their content of ascorbic acid. One of the present authors (J. S.) published in 1941 a paper on the results obtained at Kärnbolaget AB, Stockholm, up to that year. In that publication the chemical methods used were described in considerable detail, as was also the relation of ascorbic acid to yearly fluctuations, chromosome number and taxonomical position. Previously, Gustafsson1,2 and Gustafsson and Håkansson3 were engaged in genetical and cytological experiments on canina roses and undertook in 1942, with the financial support of Kärnbolaget AB, a population analysis of ascorbic acid in the roses of south Sweden. By this joint work a relation was discovered that seems to be of general importance, namely, the influence of hip fertility on the amount of ascorbic acid.
