33P uptake and carbohydrate concentrations in P deficient poplar supplied with glucose in the nutrient solution. a The recovery of 33P in whole plants relative to the total amount of 33P added to the nutrient solution. b Soluble carbohydrate concentrations as the sum of fructose and glucose in roots of poplars. The plants were grown with three different phosphate concentrations in the nutrient solutions (HP: 641 μM, MP: 6.4 μM, LP: 0.064 μM) that were supplemented with 400 mM glucose for 2 h before adding 1 mL 33P labeled nutrient solution. Controls received no glucose. Different letters indicate significant differences between treatments (p ≤ 0.05, Two-Way-ANOVA and Tukey’s honest significance test, n = 5, mean ± SE)
