    • Figure 1. 

      Effects of different Agrobacterium rhizogenes strains on infection efficiency in (a) Cynanchum stauntonii, (b) Artemisia argyi, and (c) Chrysanthemum morifolium. This result was obtained using one-way analysis of variance. Lower-case letters above the columns indicate statistically significant differences among the indicated groups (p < 0.05, Duncan's multiple-range test).

    • Figure 2. 

      Effects of different inoculation methods on infection efficiency in (a) Cynanchum stauntonii, (b) Artemisia argyi, and (c) Chrysanthemum morifolium. This result was obtained using one-way analysis of variance. Lower-case letters above the columns indicate statistically significant differences among the indicated groups (p < 0.05, Duncan's multiple-range test).

    • Figure 3. 

      Acquisition of positive materials in Cynanchum stauntonii via a tissue-free inoculation method. (a) The inoculation process of Cynanchum stauntonii without tissue culture. (b) Growth status of positive materials at different stages in Cynanchum stauntonii explants.

    • Figure 4. 

      Acquisition of positive materials in Artemisia argyi via a tissue-free inoculation method. (a) The inoculation process of Artemisia argyi without tissue culture. (b) Growth status of positive materials at different stages in Artemisia argyi explants.

    • Figure 5. 

      Acquisition of positive materials in Chrysanthemum morifolium via a tissue-free inoculation method. (a) The inoculation process of Chrysanthemum morifolium without tissue culture. (b) Growth status of positive materials at different stages in Chrysanthemum morifolium explants.
