Averages of germination potential (GP), germination rate (GR), germination time (GT), germination index (GI), and seed vigor index (SVI) are given. Treatments that do not have the same letters are significantly different (p < 0.05) as determined by Duncan’s multiple range tests. Each point represents the mean of three replicates. The values presented are the mean ± standard deviation (SD). Significant differences among treatments were determined using a three-way analysis of variance (ANOVA).
