The phenotypes of the transgenic pear lines overexpressing PcDWF1 and control pear plants. a The expression of PcDWF1 in the transgenic pear lines and control pear plants. b The phenotypes of the transgenic pear lines and the control pear plants on rooting medium for 50 days. c The growth state of the transgenic pear lines and the control pear plants on subculture medium for 50 days. The plant height (d) and the root number (e) of the transgenic pear lines and the control pear plants on rooting medium for 50 days. (f) The pear height changes in the transgenic pear lines and control pear plants on subculture medium in 50 days. Data are the means ± SD of triplicate experiments. Asterisks (*) indicate significant differences from the control (Student’s t-test, *P < 0.05, **P < 0.01)
