Figure 2

Effects of different hormone combinations of leaf cuttings taken from Chinese fir clones. Treatment numbers 1–16 are shown on the x-axis, and values for the three different clones are represented by the three different colored columns. (a) Callus initiation rates; (b) rooting rates; (c) root length; (d) bud germination rates; (e) plantlet formation rates. Different lowercase letters above the columns indicate significant difference between treatments for the same clone (p < 0.05). Different capital letters indicate significant difference between clones under the same treatment (p < 0.05). Values are means and the error bars represent standard error.
