SOME OBSERVATIONS ON POLLINATION AND FRUIT SETTING IN ECUADORIAN CACAO
Notice bibliographique
Résumé
U H l N G a short stay at the Swedish Hacienda Clenientina in ihe D neighbourhood of Bnbahoyo, Ecuador, I had an opportunity to make some observations and experiments roncerning pollination and fruit setting in Theobromu cmxio.Four trees growing close to the hacienda and numbered 2, 3, 4 and 5 were used for the experiments.The origin of these trees is not quite clear, but they are most probably derived from crosses between ))Cacao National,, the widespread native cacao variety of Ecuador, and trees raised from seeds imported from Venezuela.A total of 156 flowers were pollinated, 81 with pollen froin the same tree, 75 with pollen from other trees.On account of the structure of the flowers, which normally prevents spontaneous self-fertilization, it was not necessary to emasculate the flowers.However, before pollination the virginity of the stigmata was controlled with the help of a strong lens.Only flowers newly opened were used, and these were pollinated in thr morning or some time before noon.Results of self-pollincrtions.-On trees Nos. 2, 3 and 4 all selfpollinated flowers were abscissed and fell to the ground before the end of the 3rd day.The numbers of pollinated flowers were 14, 29 and 13 respectively.A few of theso flowers, however, were used for fixation €or embryological studies before the flowers had yet fallen.Nevertheless the pollin:ction\ clearly sliow that these three trees are self-incompatible.The fourth tree, No. 5, on the contrary, was found to be self-compatible.Of 13 self-pollinated flowers, which were allowed to develop up to 12 days before they were fixed, 11 showed 2111 obvious fruit setting and an even and regular development.Twelve additional self-pollinated flowers were fixed within 3 days, before it was possible to decide whether the pollination had been successful.However, all ovaries in these flowers when observed more than 24 hours after pollination sliowed an obvious swelling, indicating a positive result also Commencing fruit development Cross combination Flowers abscissed 3 x 5 . . . . . .
