Figure 1.
Rooting response in whip grass cuttings under treatment of NAA dosage and soaking duration in 2011.
Comparative graph of rooting percentage (A), number of adventitious roots (longer than 2 cm) per cutting (B) and root dry weight per cutting (C). 0 min soaking duration of different NAA dosages (0 mg/l, 100 mg/l, 200 mg/l, 300 mg/l and 400 mg/l) was without treatment and considered as control. Different small letters mean significant differences among treatments of NAA dosage and soaking duration at 30 DAP at α = 0.05. Values represent a mean of 3 replicates with SD. LSD Test.

Figure 2.
Effect of NAA dosage and soaking duration on some enzyme activity in whip grass cuttings in 2011.
Comparative graph of IAAO activity (A), POD activity (B) and PPO activity (C). 0 min soaking duration of different NAA dosages (0 mg/l, 100 mg/l, 200 mg/l, 300 mg/l and 400 mg/l) was without treatment and considered as control. Different small letters mean significant differences among treatments of NAA dosage and soaking duration at 10 DAP (induction phase) at α = 0.05. Values represented a mean of 3 replicates with SD. LSD Test.
