Study of a comprehensive appraisal method for a grain postproduction system.

Apples were pressure infiltrated with calcium chloride solutions at harvest during 3 separate growing seasons. In 1984, the calcium concn of Golden Delicious and Delicious apples ranged from 170 to 1600 and 200 to 2000 micro g/g, respectively. In 1988, the calcium concn of Delicious fruit ranged from 200 to 1050 micro g/g; similarly, that of Golden Delicious apples was 193-1046 micro g/g in 1989. Calcium concn was negatively correlated with decay caused by the 3 fungal pathogens tested during these 3 years. However, calcium reduced decay to a greater extent (70%) in fruit inoculated with Glomerella cingulata than in fruit inoculated with Penicillium expansum (37%) or Botrytis cinerea (50%). Thus, calcium-induced resistance to postharvest fungal pathogens is broad in spectrum.
