Demonstration of branch rooting. (a) Morphology of roots after opening the high-pressure propagation box, with new shoots emerging from the branch. (b) The morphology of roots formed under the treatment of different A. rhizogenes strains, showing their growth from the girdling site. CK means the normally formed roots of T. media branches without the treatment of A. rhizogenes. (c) The rooting rate of T. media branches under the treatment of different A. rhizogenes strains that, without the treatment of A. rhizogenes, was as a control (CK). (d) The number of adventitious roots in T. media branches under treatments of different A. rhizogenes strains that, without the treatment of A. rhizogenes, was as a control (CK). (e) The growth status of the rooting branches induced by A. rhizogenes strains MSU440 and C58 after being transplanted into pots. Each experiment was repeated three times. Each replicate contains at least 35 branch rooting treatments. Asterisks indicate significant differences (*** p < 0.001).
