Leaf and stem traits of Rhus typhina and Vitex negundo var. heterophylla with different watering and cultivation treatments.
Ctotal Total chlorophyll content, LMA Specific leaf weight, γ The ratio of square of leaf perimeter to leaf area, ρstem Stem specific density. The different lower case letters indicate significant differences between the treatments for each species and ns indicates no significant treatment effects (P ≤ 0.05, Tukey’s test). Bars are means ± SE (n = 5 for Ctotal, n = 10 for LMA and γ, and n = 6–10 for ρstem).
