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. |

In previous studies we observed that the elimination of seminal plasma from ejaculated sperm before freezing was to obtain a good recovery of motility of spermatozoa (spz) after thawing. However, when the motility is tested immediately after ejaculation we find that seminal plasma obtained during the breeding season (BSSP), exhibits a positive effect on the maintenance of motility whether these spermatozoa are of breeding or of non-breeding season. In contrast, seminal plasma of non breeding season elicits a strongly negative effect. This negative effect is also observed when epididymal spermatozoa are used instead of ejaculated spermatozoa. Epididymal spermatozoa exhibit a much longer survival time than ejaculated spermatozoa in the absence of added material and, BSSP is without any effect. Thus the positive effect of BSSP on ejaculated spermatozoa is probably due to the inhibition of the negative factor from seminal plasma. Very likely, this negative factor acts rapidly explaining the shorter survival time of ejaculated spermatozoa compared to epididymal spermatozoa. This hypothesis is strengthened by the observation that a protein fraction from bulbourethral glands secretion exhibits a very strong negative effect on the motility of epididymal spermatozoa. The effect of this factor can be inhibited by material from the seminal vesicles. Thus variations of fertility of goat spermatozoa as a function of season might be controlled by the balance between these two factors. |
