Effects of low light on photosynthetic properties, antioxidant enzyme activity, and anthocyanin accumulation in purple pak-choi (<i>Brassica campestris</i> ssp. <i>Chinensis</i> Makino) - Fig 2

<p>Effects of low light treatment on chlorophyll a (A), chlorophyll b (B), carotenoid (C) and anthocyanin (D) content in leaves of purple pak-choi seedlings. The data are the mean of three replicates, and SDs are shown as <i>vertical bars</i>. The means marked with different letters indicate significant differences between treatments at <i>p</i><0.05, as determined with Duncan’s multiple range test. Different lower-case letters at each time point indicate significant differences between treatments. FW is the abbreviation of fresh weight.
