Pre-experimental results
By performing germination tests after immersion in different
concentrations of GA3 and
H2O2 solutions, we found that the final
germination rate (Fig 1a) and germination potential (Fig 1b) of the
seeds of V. negundo var. heterophylla were greatest after
treatment with a GA3 pre-treatment solution at a
concentration of 1‰, with the final germination rate of 68.60% and the
germination energy of 22, and thus in pre-treatment solution was most
favorable for seed germination of V. negundo var.
