Fig. 5From: Field evaluation of transgenic hybrid poplars with desirable wood properties and enhanced growth for biofuel production by bicistronic expression of PdGA20ox1 and PtrMYB3 in wood-forming tissueAltered bud dormancy phenology and survival rates of transgenic hybrid poplars grown in an LMO field for long periods of time encompassing changing seasons. a Measurement of winter bud set of transgenic hybrid poplars and WT poplars from September to October 2014. Percentage bud set was calculated from 5 to 8 trees per line. b Measurement of spring bud flushing of transgenic hybrid poplars and WT poplars in April of 2015. Percentage bud flush was calculated from 2 to 8 trees per line. c Survival rate of transgenic poplars and WT poplars after winter. Percentage survival rate was calculated from 4 to 8 trees per line in June 2015. d Representative photographs showing the growth of hybrid poplars in June 2015.
