INITIAL AND FINAL FRUIT SET IN PLUM (PRUNUS DOMESTICA L.) AS AFFECTED BY DIFFERENT TYPES OF POLLINATION

摘要

The paper presents two-year results (2010-2011) of the study of initial and final fruit set in newly bred plum cultivar 'Pozna Plava' grown under agroecological conditions of Serbia, which were subjected to different types of pollination. 'Investigation included self-pollination, cross-pollination (with 'Cacanska Najbolja', 'Hanita and Presenta' as pollenizers) and open pollination. During these two years, in vitro pollen germination were also monitored.Pollen germination ranged from averagely 17 26%(Pozna Plava) to 46.48% ('Presenta') The best result with 35.69% final fruit set was under cross-pollination variant, with Prezertta as pollemzer The lowest performance was observed open pollination variant with averagely 2.61% final fruit set.
