图1 不同氮素供给条件下ACC处理对不同基因型玉米植株干重与根冠比的影响 A和B分别为ACC处理7 d后不同基因型玉米植株在不同氮素条件下根系和地上部的干重; C为ACC处理7 d后不同基因型玉米植株在不同氮素条件下的根冠比。

Fig. 1 Effects of ACC on the dry weight and the ratio of root and shoot in different maize genotypes under different nitrogen treatments A and B indicate the dry weight of roots and shoots of different maize genotypes under the different nitrogen conditions after 7 days of ACC treatment, respectively; C indicates the root-to-shoot ratio of different maize genotypes under different nitrogen conditions after 7 days with ACC treatment. LN: low nitrogen level; SN: sufficient nitrogen level.
