Table 3 Average length of development, size of 0 day buds (just prior to anthesis), and overall bud growth rates for the five Jaltomata species and S. pimpinellifolium

From: Heterochronic developmental shifts underlie floral diversity within Jaltomata (Solanaceae)

  1. Bud diameter was measured every other day, from 1 mm buds to anthesis. Growth rate was determined by dividing bud diameter of day 0 buds by the length in days. Significant differences among species are indicated by different letters (following ANOVA and Tukey’s HSD)
