Fig. 2. — Abundance in carbon (C) units of water-soluble carbohydrates (WSCs). WSCs were measured in plants grown under high (HN) and low nitrate (LN) supply, 1 h and 48 h after defoliation. Relative abundance in C units was calculated by multiplying peak intensity by degree of polymerization (DP). WSCs with a DP from three to eight are referred to here as low molecular weight (LMW) WSCs, and DP9 to DP20 are referred to as high molecular weight (HMW) WSCs. The total concentrations of LMW and HMW WSCs are shown in (A) leaf sheaths and (B) roots after 1 h; (C) leaf sheaths and (D) roots after 48 h. Values are means ±SE (n=5 pools of five plants each). Means were tested for significance using a two-tailed t-test. Asterisks denote significantly different means between intact plants (grey) and defoliated plants (black) (*P<0.05, **P<0.01, ***P<0.001).
