Averages of stem fresh weight (SFW), stem dry weight (SDW), root length (RL), and stem length (SL) are given. Treatments that do not have the same letters are significantly different (p < 0.05) as determined by Duncan’s multiple range tests. Each point represents the mean of three replicates. The values presented are the mean ± standard deviation (SD). Significant differences among treatments were determined using a three-way analysis of variance (ANOVA).
