Development and Ripening of Bunch in DxP palm (E. guineensis Jacq.) and Two Interspecific OxG Hybrids (E. oleifera x E. guineensis) at Unipalma S.A.
The criteria for harvest in OxG hybrids have been extrapolated from E. guineensis, being fulfilled without accurate knowledge about bunch growth and ripening. The physiological changes during bunch growth and ripening in a dxp material of Brabanta x Ekona.Nifor origin and two OxG interspecific hybrids of Ekona x Nifor (OxG1) and Brabanta. Deli x Yangambi.Nifor (OxG2) origin were analysed. At anthesis, 36 inflorescences were selected to analyse fruit growth and color changes and, as of 84 days after anthesis (daa), oil content in the internal, external, and parthenocarpic fruits of the bunch in a completely randomized design, three repetitions, and 12 sampling dates. OxG1 hybrid presented greater dry matter accumulation in the bunch and initiated oil accumulation 112 daa. OxG2 hybrid initiated oil accumulation 126 daa and it presented higher oil/bunch content (32%), being the parthenocarpic fruits those of greater participation. For dxp and OxG1 hybrid, oil percentage was 24%, being the external normal fruits those of greatest proportion. Fruit pigment changes initiated 112 daa and fruit detachment and splitting between 140 and 154 daa. When the bunch was fully ripened (168 daa), OxG2 hybrid presented fruit splitting with little natural detachment, whereas in OxG1 hybrid and dxp, fruit detachment was high and splitting was minimum.
