图1 外源复合有机酸(OA)对铝胁迫下菊芋根长与株高的影响 Al0、Al350和Al700表示铝浓度分别为0、350和700 μmol?L-1; OA0、OA30、OA60和OA90表示复合有机酸浓度分别为0、30、60和90 μmol?L-1。XZ: 徐州菊芋; ZY: 资阳菊芋。不同小写字母表示同一时期不同处理组间差异显著(P<0.05)。

Figure 1 The effect of exogenous compound organic acid (OA) on the root length and plant height of Helianthus tuberosus under aluminum (Al) stress Al0, Al350, and Al700 indicating concentrations of Al are 0, 350, and 700 μmol?L-1, respectively; OA0, OA30, OA60, and OA90 indicating concentrations of OA are 0, 30, 60, and 90 μmol?L-1, respectively. XZ: H. tuberosus cv. ‘Xuzhou’; ZY: H. tuberosus cv. ‘Ziyang’. Different lowercase letters indicate significant differences among treatment groups at the same period (P<0.05).
