Experiments were conducted to examine the growth and development of oil palm Elaeis guineensis Jacq. (Magnoliophyta: Arecaceae) seedlings subjected to shading, irrigation regimes and mycorrhizal inoculation in the dry season. Treatments were 2 x 2 x 2 factorial combination consisting of shade and no-shade (open sun), 7 and 14 day irrigation intervals and mycorrhizal inoculation or non-inoculation. Seedlings that were grown under shade and irrigated weekly produced highest number and length of fronds, and shoot, leaf and frond weights in addition to taller plants compared to open sun (unshaded) seedlings. Across irrigation treatments, unshaded seedlings had lower weights of leaf, frond and shoot biomass. The effects of shade treatments were significant on plant height and frond length from 2 to 20 weeks after planting. The seedlings irrigated fortnightly produced longer roots compared with the unshaded and weekly irrigated. Fortnight irrigation enhanced root development compared with weekly irrigation. Shading and weekly irrigation significantly enhanced soil moisture contents and seedling water use efficiency compared with the unshaded. Shaded seedlings irrigated weekly used larger amount of water compared with fortnight irrigation. Significant interactions were obtained between shade and irrigation regimes for most of the growth parameters measured. Mycorrhizal inoculation, shaded and weekly irrigated seedlings were more vigorous compared with the unshaded and non-inoculated.

El objetivo de este estudio fue realizar un análisis comparativo de las características físicas y químicas de racimos de genotipos de Elaeis oleifera y de sus híbridos interespecíficos OxG con Elaeis guineensis, determinando los componentes y el potencial del aceite del racimo, y la calidad de los aceites, analizando el contenido de ácidos grasos, vitamina E y carotenos. En el estudio se utilizaron racimos provenientes de inflorescencias sin polinización asistida con la presencia perimetral de E. guineensis. Se utilizó un diseño experimental completamente al azar con tres unidades experimentales, cada una conformada por tres racimos. Los mayores cuajados del fruto se encontraron en el genotipo de E. oleifera Sinú (76,53 %) y el híbrido OxG II (72,64 %). Los potenciales de extracción de aceite fueron superiores en los materiales híbridos OxG destacándose el II (20,82 %). Las palmas E. oleifera presentaron mejores perfiles de ácidos grasos, destacándose los materiales del genotipo Sinú (79,1 % de ácidos grasos insaturados) y los del híbrido II (70,2 %). Para el contenido de vitamina E se confirmó la alta calidad del aceite de los materiales de E. oleifera, sobresaliendo el genotipo Coarí (1.006,7 ppm) y el híbrido II (1.549,6 ppm); el material del genotipo Sinú registró el mayor contenido de carotenos totales (1.524,7 ppm).
