Effects of ZnO NPs on the content of chlorophyll (Chl.) in rice seedlings under chilling stress. Chl. a (A), Chl. b (B), and total Chl. (C) in leaves of rice seedlings subjected to 0, 25, 50, and 100 mg/L of ZnO NPs under chilling stress were measured, respectively. The tests were repeated three times. The data given are the averages of three replicates, with the standard deviation (SD) shown by the error bars. Different letters above or below error bars show the differences at p < 0.05.
