Anthocyanin content and UVB sensitivity in Brassica rapa
1996
Klaper, R. | Frankel, S. | Berenbaum, M.R.
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.
