  1. Values are expressed as mean ± SE (n = 5). The different letters indicate significant differences between treatments (P < 0.05) based on Tukey’s multiple comparison test, two way ANOVA. Different lowercases and uppercases indicate significant differences among different treatment. PHI, plant height Increments in; BNI, blades number increment; LAI, leaf area increment; FSW, fresh shoot weight; FStW, fresh stem weight, DStW, dry stem weight; ARsFW, adventitious root fresh weight; ARsDW, adventitious root dry weight; PRsFW, primary root fresh weight; PRsDW, primary root dry weight. ARs roots were not found in CK group.
