图1 UV-B胁迫下不同浓度Ca2+对颠茄初始荧光(A)和最大光化学效率(B)的影响 不同小写字母表示相同处理时间不同浓度Ca2+处理间差异显著(P<0.05)。T1至T5分别代表UV-B胁迫下不同浓度Ca2+处理组, 分别为0 mmol L-1、2 mmol L-1、4 mmol L-1、6 mmol L-1和8 mmol L-1。T0表示未进行任何处理, 即空白对照组。

Fig. 1 Effects of Ca2+ on Fo (A) and Fv/Fm (B) of Atropa belladonna L. under UV-B stress Bars superscripted by different letters are significantly different among different treatments of Ca2+concentration in the same treating days at the 0.05 level. T1 to T5 indicate different treatments of Ca2+ concentration (0, 2, 4, 6, and 8 mmol L-1) under UV-B stress. T0 indicates untreated blank control groups.
