The antiscorbutic potency of apples. V

Abstract

CULTIVATED varieties of apples fall into two groups as regards the chromo- some number of their nuclei, the so-called diploids with 34 and triploids with 51 chromosomes respectively. Preliminary experiments [Crane and Zilva, 1931] have shown that triploid apples reveal a tendency to possess a higher vitamin C content than diploids. The number of varieties tested in the experiments mentioned was, however, small and it was felt desirable to extend it. In this communication the results of tests carried out with a further number of triploid varieties are given and are compared with those previously obtained with triploid and diploid apples.
