图3 不同浓度外源MeJA对UV-B胁迫下颠茄叶片多胺含量(A), 多胺总量(B)和(Spm+Spd)/Put比值(C)的影响 标以不同小写字母表示不同处理组间差异显著(P < 0.05)。处理同表2。

Fig. 3 Effects on Polyamine contents (A), PAs contents (B) and (Spm+Spd)/Put (C) under exogenous methyl jasmonate with different concentrations in A. belladonna leaves under UV-B stress Bars superscripted by different lowercase letters show significant differences among different treatment groups at P < 0.05. Treatments are the same as those given in Table 2.
