Measurement of plant growth and biomass yield in transgenic poplar plant. a Images of 5-month-old transgenic poplar lines and wild type (WT); Scale bar as 10 cm. b, c Observation of plant growth in the transgenic lines and WT during time course of 6 months. d–f Plant height, stem diameter and dry weight (biomass yield) in the transgenic lines and WT of 6-month-old. Data represent mean ± SD of five biological replicates. Student’s t test was performed between the transgenic lines and WT as **P < 0.01
