Fig. 1. Shading strategies used for the chrysanthemum ‘Purple Reagan’. The capitulum, all leaves or the whole plant were 100% shaded during S1 (bud stage) using silver paper, and
seedlings treated with a fluorescent lamp were used as the control group. When the plants developed to S5 (fully open stage), the silver papers were removed, and the corresponding
color phenotypes of the ray florets were observed. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this
article.)
