Specimens were pruned by the removal of aerial growth prior to harvest and starch granules were isolatend from the roots of pruned and control plants after harvest.The glassiness and hardness of cooked roots from the pruned plants showed an increase of 60-70% and 40-60% respectively compared with the controls. Although there was some reduction in the size of the starch granules derived from the pruned roots as compared with the control, pruning had negligible effects upon X-ray crystalinity, amylose/ amylopectin contents, the elution patternos of the isolamylase debranched starch,the susceptibility of the granules to enzyme digestion,their swelling power and solubility, the temperature and enthalpy of gelatinisation and their behaviour in the Rapid Visco Analyser. Minor differences were observed when pruned and control samples were examined in the Brabender amylograpph.  adigestibility  atexture  aamylose/ amylopectin ratio  aGlassiness  aX-ray crystallinity1 aBLANSHARD, J.
