在存在和不存在高水平短波紫外线（UVB，280-325 nm）辐射的情况下生长三种花青素含量不同的快速循环甘蓝基因型。 41 天后，UVB 暴露降低了所有基因型的叶长和株高。花青素水平较低的植物的花朵数量减少是花青素水平正常或升高的基因型的两倍；然而，花青素水平正常和升高的基因型在开花结果上没有差异，这表明花青素色素沉着以外的因素也有助于该物种的 UVB 反应。
Three genotypes of rapid-cycling Brassica rapa that differ in anthocyanin content were grown in the presence and absence of elevated levels of shortwave ultraviolet (UVB, 280-325 nm) radiation. After 41 days, UVB exposure reduced leaf length and plant height of all genotypes. Plants with low levels of anthocyanin experienced a reduction in flower number twice as great as in genotypes with normal or elevated levels of anthocyanins; however, the absence of differences in flower production by genotypes with normal and elevated levels of anthocyanins suggests that factors other than anthocyanin pigmentation contribute to UVB responses in this species.
