Figure 5.

Chromatograms of WSCs in the plant parts of perennial ryegrass that were subjected to 14 d of drought followed by 14 d of rewatering. Fructans from elongating leaf bases (0.15 mg), from leaf sheaths (0.20 mg), and from leaf blades (0.20 mg) were applied to the CarboPac PA100 column. Glc, Fru, and Suc were eluted between 2 and 5 min, fructans with low DP (<8) between 6 and 15 min and high DP fructans (DP < 8) between 16 and 30 min, according to the identifications obtained by Pavis et al. (2001).
