Physiological comparison between the faster-growing Neva and control I-214. a The change in stem radius of the two genotypes from June to September, as measured using a point dendrometer. The three expanded plots provide higher resolution for variation in different growth stages. b Representative stems from the two genotypes in the pre-growth, fast-growth and post-growth stages. c The stem radial daily increment of the two genotypes in three growth stages. d The maximum daily shrinkage of the two genotypes in three growth stages. e The transpiration rates of the two genotypes in three growth stages. f The maximum net photosynthetic rates of the two genotypes in three growth stages. g The stem relative water contents of the two genotypes in three growth stages
