Summary: | Abstract The objective of this work was to evaluate the viability of genipap (Genipa americana) pollen grain at room temperature in different culture media. The experimental design was completely randomized in a 3x11 factorial arrangement (culture media x incubation times) with four replicates. The number of germinated pollen grains was analyzed at 24-hour intervals up to 288 hours after incubation at room temperature. The culture medium with 100 mg L-1 H3BO3, 80 g L-1 sucrose, and 1.0 g L-1 agar results in a higher to intermediate germination percentage, being the most suitable for studies on the in vitro viability of genipap pollen grains.
Resumo O objetivo deste trabalho foi avaliar a viabilidade in vitro do grão de pólen de jenipapeiro (Genipa americana) à temperatura ambiente, em diferentes meios de cultura. O delineamento experimental foi inteiramente casualizado em arranjo fatorial 3x11 (meios de cultura x tempos de incubação), com quatro repetições. O número de grãos de pólen germinados foi analisado em intervalos de 24 horas até 288 horas após incubação em temperatura ambiente. O meio com 100 mg L-1 de H3BO3, 80 g L-1 de sacarose e 1,0 g L-1 de ágar resulta em alta à média percentagem de germinação in vitro, sendo o mais adequado para estudos da viabilidade in vitro de grãos de pólen de jenipapeiro. |
