图5. 海藻糖处理影响干旱胁迫下水稻叶片内信号分子的含量和相关酶活性
(A) 钙离子含量; (B) 一氧化氮含量; (C) 硝酸还原酶活性; (D) 己糖激酶活性。缩写同图1。图中数值代表来自3个生物学重复的平均值±标准差(n=6)。不同小写字母的柱值表示差异显著(P<0.05) (Student-Neuman-Keuls)。

Figure 5. Trehalose treatments affect the content of signal molecules and the activity of related enzymes in rice leaves under drought stress
(A) Ca2+ content; (B) NO content; (C) Nitate reductase (NR) activity; (D) Hexokinase (HXK) activity. Abbreviations are the same as those given in Figure 1. Values represent means±SD (n=6) from three biological replicates. Bars labeled with different lowercase letters indicate significant differences (P<0.05) (Student-Neuman-Keuls).
