Figure 3. The effect of MyA on the embryo mask areas during seed germination of Lepidium sativum.
Time course of mask areas of embryos extracted from seeds at different times during incubation (a) without (CON) and (b) with 5x10-4 M MyA, and 0, 10, 20 or 30 mM PEG in continuous light. Typical examples of embryo masks from each seed population at different times are shown below the graphs. Box-whisker-plots each representing data from 50 embryos are shown with the whiskers representing the minimum and maximum of the data distribution, the bottom and top of the boxes the 25th and 75th percentiles and the horizontal bar the median.
