Evaluación de la viabilidad y germinabilidad del polen durante la labor de polinización asistida en campo: Evaluation of the Feasibility and Germinability of Pollen during Assisted Pollination in Oil Palm Crops
Assisted pollination is a priority task in the cultivation of the interspecific OxG hybrid that allows to maintain its yield and improve the formation of bunches. The pollen used in this work comes from African palm (Elaeis guineensis) and it is applied by trained operators who perform this activity during approximately eight hours of a working day. Given the importance of pollen on assisted pollination in the cultivation of the OxG hybrid, the ability of this compound to stay alive (viability) and to germinate (germinability) during 8 hours of a field work day was monitored. To do this, pollen was put to germinate in vitro in agar medium in Petri dishes. The dishes were incubated at 37 ° C for 120 min and germination verified by visual inspection under a microscope. In this evaluation, carried out in the Colombian Southwestern (Tumaco) and Central oil palm zones (Barrancabermeja), it was observed that the percentage of viability between the start and the end of the working day did not vary beyond 10%, while the germinability did not exceed 25% variation between the start and end of eight hours of the work day. Taking into account this range of variation, it is recommended to avoid the use of pollen with germination below 50% and ensure the quality of this input using pollen with germination close to or greater than 70% for the assisted pollination of OxG hybrids.
