Germinability and pollen viability of four improved cultivars of palm oil under laboratory conditions
The success of assisted pollination in oil palm is essential for oil production, since it determines the amount of well-formed fruits; in this process, the pollen quality, expressed as viability and germinability, is of great importance.

| description |
The success of assisted pollination in oil palm is essential for oil production, since it determines the amount of well-formed fruits; in this process, the pollen quality, expressed as viability and germinability, is of great importance. This work was carried out in the Salamanca Oleaginosas S.A. Laboratories, in order to determine the viability, germination and pollen tube growth of pollen grains of Guineensis, Amazon, Coari x Lame and Unipalma genotypes, stored during 0, 5, 15 and 30 days at room temperature, and -13 °C. Using an unrestrictedly randomized design with a factorial arrangement and four replications, the variables percentage of viability and germination, length and growth rate of the pollen tube were analyzed. Guineensis pollen had the highest germination and viability values, which ensure a good pollination efficiency, while the other cultivars had values below the recommended, although pollen tube growth of the few grains that germinated was similar to Guineensis. |

El presente trabajo se realizó en los Laboratorios de la empresa Salamanca Oleaginosas S.A., con el objeto de determinar la viabilidad, germinación y velocidad de crecimiento del tubo polínico de granos de polen de los genotipos Guineensis, Amazon, Coari x Lame y Unipalma, almacenados durante 0, 5, 15 y 30 díasa temperatura ambiente y a -13 °C. Se empleó un diseño DIA con un arreglo trifactorial (Genotipos, tiempo y temperatura de almacenamiento) con cuatro repeticiones. El polen del genotipo Guineensis presentó los mayores valores de viabilidad y germinación, asegurando una buen eficiencia en la polinización, mientras que los demás cultivares presentaron valores por debajo de los recomendados; sin embargo, el crecimiento del tubo polínico del polen germinado en estos genotipos, fue similar al del genotipo Guineensis.application/pdfspaUniversidad Nacional de Colombia - Sede Medellín - Facultad de Ciencias Agrariashttps://revistas.unal.edu.co/index.php/refame/article/view/69587Universidad Nacional de Colombia Revistas electrónicas UN Revista Facultad Nacional de Agronomía MedellínRevista Facultad Nacional de Agronomía MedellínCriollo Escobar, Hernando and Dominguez Chauza, John Jairo (2018) Germinability and pollen viability of four improved cultivars of palm oil under laboratory conditions.
