Growth in Tree Nursery of Oil Palms Elaeis oleifera x Elaeis guineensisand Elaeis guineensis x Elaeis guineensis in Tumaco, Colombia
The knowledge of the growth in tree nursery of perennial plant species is important in order to develop good agronomical practices for the selection of the plants that will be taken to the fields. This information is required for the hybrids OxG of oil palms under the conditions of the palm growing Colombian region. In two soils with different moisture retention and air space, the growth and development in nursery of hybrid oil palms OxG F1 (Elaeis oleifera x Elaeis guineensis) and Tenera DxP (Elaeis guineensis x Elaeis guineensis) were evaluated. Plants of OxG material were larger and accumulated more biomass in most of its constituent bodies in comparison with plants of DxP material. Likewise, both plants were quite different in the order of preference distribution and accumulation of assimilated species at the petiole basis, stem and petiole. In comparison with DxP, the OxG material showed the differential characteristic to allocate more of their assimilated species growth the plant root system. Moreover, it was determined that OxG plants exhibit better growth and development compared with DxP plants in nursery stage with high moisture retention and low aeration soils. Additionally, we identified and selected three morphological features with discriminatory authority to differentiate the growth behavior of the two types of oil palms regarding the soil used in the nursery: section area of the petiole (PxS), rachis length (RL) and leaf emission (LE).
