抄録

The author has previously carried out field surveys and analyses of field samples and found that the manganese content in apple trees varies with the kind of rootstocks and soil conditions and also that the manganese content is closely related to the incidence and the degree of the physiological disorder, rough bark. In order to further substantiate this relationship, 2-year-old seedlings of Rails apple that had been grafted on Malus sieboldii (Ralls/sieboldii for brevity) or on Malus pruniforia (Rails/pruniforia) were prepared, and these were grown by sand culture solutions containing manganese in different concentrations (0.5, 30 and 45ppm) from the beginning of May to the middle of October, after which they were analyzed for manganese. The results were examined in relation to the occurrence of the disorder. From this, the following points seem to become clear.
