Fig. 4From: The effects of persistent drought and waterlogging on the dynamics of nonstructural carbohydrates of Robinia pseudoacacia L. seedlings in Northwest ChinaDynamics in the concentrations of fructose, glucose, sucrose and starch. The concentrations at the beginning of the experiments (initial, 0-day, black bar), first sampling (10-day, red bar), second sampling (20-day, green bar) and at the end of the experiments (third sampling, 30-day, yellow bar) water status treatments on the whole seedling level in 2015 (a, c, e and g) and 2016 (b, d, f and h). The treatments are ED: extreme drought, MD: 30% of the field capacity (FC), W70: 70% of the field capacity, FC: field capacity and WL: permanently waterlogged. Values are back-transformed averages, and the error bars represent 95% confidence intervals for fructose and glucose. Note that the upper-case letter refers to the significant differences among treatments and the lower-case letter refers to the significant differences within-subjectBack to article page
