The flower organization properties of the C. 970 Besztercei plum clone variety on 10 myrobolan seedling stocks were examined between 1977 and 1981. The rootstock combinations greatly varied in the process of organization. The length of the petiole and the pollen germination, on the other hand, showed a considerable dependence on the year. Self- and open pollination similarly fluctuated during the years of observation. There is a relationship between the fertility /as a function/ and structure of the flower. Flowers with larger petals and small stigma diameters generally set better than those with the opposite characteristics. The examinations have proved that it is necessary and worth-while to place the variety testing on a sounder basis, especially to concretize it by the rootstock types. The rather infrequent flower organ teratomata could be explained by the correlation of reproductive organs. Fertility can thus be influenced by the rootstock, which is of great economic importance.
