| Abstract:
The structural examinations of Prunus flowers are continued by the author, in the beginning the description of varieties and the relationship of structure and function of flowers interested him. In over 100 varieties there are important characteristics on parents and progenies of plums such as average of petal size, pistil length, diameter of stigma, stamen number, relative stamen number, germination of pollens, apistilly and polycarpy of kinds. The father's effect was very strong in genetic control of self-fertility, for which the relationship was evident with gynoecium and androecium. Large flowers and pistil form appeared dominant in the father's cultivars in progenies of Agen plum, there were father cultivars as Pond's seedling, Grand Duke and Pacific, quite like the role of plum Wangenheim affected in series of Cacanska cultivars. There are similitudes between morphological characters of the varieties Tuleu gras and Utility through Sermina as father component, but they have differences too and because cv. Tuleu gras is male sterile and cv. Jefferson (both mother component) has very suitable pollen. Parent's analysis with flower features of Ruth Gerstetter, Methley and Plovdivaja desertna gave some results, which will help more modern examinations of the hybrids as possibilities of new cultivars and moreover application of morphogenetic characters on selection and assortment analysis. | |
