Book excerpt: These studies demonstrated that the principal factors controlling the susceptibility of cultivars to physiological deterioration are environmental: plants defoliated due to severe stresses were markedly more resistant than non-defoliated plants of the same cultivar. Site and prevailing pre-harvest environmental conditions also affected the degree of susceptibility. Pruning experiments gave results which closely agreed with the defoliation effects and confirmed reports that pre-harvest pruning induced resistance to physiological deterioration. Such induced resistance was maintained for at least nine weeks after pruning and was unaffected by subsequent regenerative growth. A reduction in root dry matter content occurred following pruning but this was not causally related to resistance to physiological deterioration.
