  1. The monosaccharide composition is expressed in μg anhydro monosaccharide per mg cell wall material, and DE as the molar ratio of methanol to uronic acid in %. Peelability stages: ND, detachability not developed; DD detachability developing; FD, fully detachable peel. TS, total non-cellulosic sugars (TFA-hydrolysable neutral monosaccharides plus uronic acid). Rha, rhamnose; ara, arabinose; gal, galactose; UA, uronic acid; fuc, fucose; xyl, xylose; man, mannose; glc, glucose. Data are means of n = 4 ± standard deviation. (^) and (^^) represent statistical significance (p value <0.05) between GP and PP at the same developmental stage (DD or FD)
  2. arepresents statistical difference of DD compared to FD
