L.  aIn vivo fertilization of banana.h[electronic resource]  c2014  aThe aim of this research was to study the in vivo fertilization process of banana cultivars. The diploid hybrid (AA) 091087-01 was the male progenitor. Flower samples were checked for fertilization from the fi rst to the twentieth day after pollination. The size of the diploid ovules increased gradually at the beginning of the seed formation process. On the other hand, in the AAA triploids (Cavendish subgroup), the not fertilized ovules were aborted. In the AAB triploids (Prata subgroup) some ovules were fertilized. The fl owers of Grand Naine, Nanicão and Pacovan cultivars presented necrosis in the distal part of the ovary on the fi rst day after pollination. Necrosis can hinder pollen tube growth towards the ovule, which might be related to the low seed yield in 'Pacovan' cultivars and to the absence of seeds in the Cavendish subgroup cultivars. hibridação, óvulos.  aBananas  aBreeding  aGenetic improvement  aIn situ hybridization  aMusa  aOvules  aBanana  aHibridação  aMelhoramento vegetal  aMétodo de melhoramento  aProdução vegetal1 aSOUZA, E.
