However, theconsequences of these procedures on the results are unknown. This study measured the germination processof Bowdichia virgilioides based on different seed sample sizes. The assay was conducted in a germinationchamber under continuous fluorescent white lamps and 26.2 ± 2.5 ºC. The design was completelyrandomized, as a 3 x 3 factorial (three sample sizes x three seed lots), with four replications per treatment.The sowing was done in gerbox, each one containing 25 seeds, making up 100, 200 and 400 seeds persample analyzed. Germinability, time (first, average and final), speed (mean germination rate and Maguire’sindex – VE or IVG), coefficient of variation of the germination time, uncertainty and synchrony of thegermination process were evaluated. Those seeds with embryo protrusion were considered germinated.Germination relative frequency graphics were also made. Among these measurements, the most fragile to size sample were VE and the uncertainty. VE was also influenced by the relation between germinability andmean germination rate, demonstrating its instability to measure the speed of the germination process whenthe lots have different germination capacity. Results of time measurements, uniformity, mean germinationrate and germinability were not affected by seed sample size. Germinability, however, was the most stablegermination measurement, and was not affected by sample size, even when analyzed by seed lots with verydiscrepant quality.</p> |
