Figure 3
Association plot between cutting treatment and seed maturity on seedling emergence. This plot represents the signed contribution to Pearson’s χ2 for each cell in a two-way contingency table. Each cell constitutes the probability of seedling emergence for each treatment combination and is represented by a rectangle whose area is proportional to the difference in observed and expected frequencies. The rectangles are placed relative to a baseline (dashed line) indicating independence. If the observed frequency of a cell is significantly greater than the expected one, the rectangle rises above the baseline (colored blue). Conversely, if the observed frequency is significantly lower than the expected frequency, the rectangle falls below the baseline (colored pink). Light gray rectangles represent frequencies that do not differ from significantly from expected values. The figure shows that WIS from both mature and immature fruits emerged more than chance, and that seed fragments cut in four from immature fruits emerged less. Additionally, there were fewer non-emerged WIS from both types of fruits that was expected under independence.
