Analyses of the growth progress of shoots of TER (red boxes – full line) and END (blue boxes – dashed line) pea cultivars. The values derived from the green area on nth days (1, 5, 8,…, 21) are presented as medians (black bars) and quartiles (boxes). For better readability, the boxes are shifted in x-axes to not to overlap, but still represent the values measured on the same days. A) A total green area. B) A normalized green area. C) A relative growth rate. The error bars show minimal and maximal values.
