图5 不同多肽处理对拟南芥SAM大小的影响 1: 未添加多肽(a, b)、添加1 μmol L-1 Brclv3Asp12多肽(c)和1 μmol L-1 BrCLV3多肽(d)处理下的野生型ler (a)和突变体clv3-2 (b, c, d)生长9 d的SAM观察; SAM相对大小是通过测量SAM侧平面上2个对生叶原基(箭头指示处)以上的面积; 标尺为50 μm。2: 不同多肽处理9 d后拟南芥SAM大小比较(e), 每种处理至少统计20个单株; 大写字母表示0.01水平下差异显著。

Fig. 5 Effects of different peptides on the SAMs in Arabidopsis 1: ler (a) and clv3-2 (b, c, d) plants were grown on 1/2 MS liquid media (a, b) containing 1 μmol L-1 Brclv3Asp12 peptide (c) and 1 μmol L-1 BrCLV3 peptide (d), and 9-day-old Arabidopsis seedlings were observed; the area of the SAM was measured on a median plane by calculating the area above the straight line from the upper edges of two opposite leaf primordia (arrowheads); Bar = 50 μm. 2: area of the SAM after different peptide treatments for nine days (e), the data and error bars represent the mean ± SD (n ≥ 20 plants for each line). Bars superscripted by lowercase letters indicate significant differences at the 0.01 probability level.
