272 Chemical-thinning Asian Pears

Specific and Sensitive Detection of Venturia nashicola, the Scab Fungus of Asian Pears, by Nested PCR

The fungus Venturia nashicola is the causal agent of scab on Asian pears. For the rapid and reliable identification as well as sensitive detection of V. nashicola, a PCR-based technique was developed. DNA fingerprints of three closely related species, V. nashicola, V. pirina, and V. inaequalis, were obtained by random amplified polymorphic DNA (RAPD) analysis. Two RAPD markers specific to V. na...

Chemical Control / New Products Evaluation of Confirm for Codling Moth and Leafroller Control in Pears

A. Full Season Evaluation of Confirm for Coding Moth Control Methods and Materials A study was conducted in a commercial 'Bartlett' pear orchard in Hood, CA. Three unreplicated treatments of ca. five acres each were applied using an air-blast speed sprayer operating at 1.75 mph and applying 100 gal of finished spray per acre. The three treatments were: Confirm 2F applied four times, Confirm 2F ...

Effect of ethylene and temperature conditioning on sensory attributes and chemical composition of 'Comice' pears.

'Comice' is among the pear varieties most difficult to ripen after harvest. Ethylene, cold temperature, and intermediate (10 °C) temperature conditioning have been successfully used to stimulate the ability of 'Comice' pears to ripen. However, the sensory quality of pears stimulated to ripen by different conditioning treatments has not been evaluated. In this study, a descriptive sensory analys...
