图2. 不同伸长时期甘蔗节间植物激素含量变化
(A) 生长素(IAA); (B) 油菜素甾醇(BR); (C) 细胞分裂素(CTK); (D) 脱落酸(ABA); (E) 乙烯(ETH)。不同小写字母表示差异显著(P<0.05), 不同大写字母表示差异极显著(P<0.01)。Ls1-Ls3同表2。

Figure 2. Changes of endogenous hormone contents in sugarcane internode during different elongation stages
(A) Indole acetic acid (IAA); (B) Brassinosteroids (BR); (C) Cytokinin (CTK); (D) Abscisic acid (ABA); (E) Ethylene (ETH). The different lowercase letters indicate significant differences (P<0.05), and the different capital letters indicate extremely significant differences (P<0.01). Ls1-Ls3 see Table 2.
