Activity of polyphenol oxidase, concentration of 3, 4-
dihydroxyphenylethylamine (dopamine), and concentration of ascorbic
acid in the pulp of bananas as they ripened were measured and relationships
between these factors and both the extent of browning and the
susceptibility to discoloration of the fruit during a 30-minute holding
period were...

Conservation biological control involves manipulating farm landscapes or management systems to enhance populations of beneficial predators of agricultural pests. Farmscaping is one aspect of conservation biological control where predators of important pests are identified, the availability on the farm landscape of resources and habitat components needed by the beneficials to...
Grapes (e.g. Vitis vinifera L.) are one of the more important fruit crops from an economic standpoint with world market values over 550 million US dollars in 2007 and 2008, second to apples (United States Department of Agriculture).
