Fig. 2From: Changes in growth and soil microbial communities in reciprocal grafting clones between Populus deltoides males and females exposed to water deficit conditionsHeight, diameter, total biomass, root biomass, root/shoot ratio, total root length, specific root length (SRL) and fine root activity in four graft clones under well-watered and water deficit. Values of different letters represent significant differences (P < 0.05) in different graft clones. Error bars SE (n = 5 individuals)Back to article page
