Effects of different treatments on plant growth and chlorophyll contents. (A,B) shoot and root length; (C,D) fresh weight of shoots and roots; (E,F) dry weight of shoots and roots. (G), SPAD value; (H), maximum quantum efficiency (Fv/m) of photosystem II. Vertical bars represent the mean ± SD of four independent replicates. Different letters above error bars indicate the significant difference between treatments and genotypes at p ≤ 0.05. T, treatment; G, genotype; T × G, the interaction between treatment and genotype.
