FIGURE 4.

Narcissi flower total scent emission under six different light:dark and temperature conditions. Volatiles were sampled at four time points (ZT). To detect scent emission patterns, we analyzed each group along time (A–F). We also compared the emitted amount under six experimental conditions at each time point (G). Each bar represents the average ± standard deviation of five flowers. Letters over bars indicate differences among time points (A–F) and groups (G) (Dunn’s test, see Tables 2, 3), LD, light:dark; DD, continuous dark; fw, fresh weight.
