Creator:: Dolcet-Sanjuan, Ramon J.
Abstract:: Appropriate micropropagation regimes were developed for four Pyrus species (P. amygdaliformis Vill., P. betulaefolia Bunge, P. calleryana Dcne., and P. communis L.) and Cydonia oblonga L. Shoot multiplication was optimal at 10 or 20μM N⁶⁻ benzyladenine (BA) and high light intensity (135μm⁻²s⁻1). Root formation of the Pyrus species was stimulated...

Creator:: Suwanagul, Anawat
Abstract:: Volatile compounds of eight pear varieties were isolated and identified by GC/MS. A total of 112 components were identified from headspace of intact fruits, including 47 compounds reported for the first time in pear. The volatile profiles of these pear varieties were characterized by esters, alcohols, hydrocarbons, aldehydes and ketones....

Abstract:: The dynamics of N was studied in field grown Comice/Provence quince BA29 pears in Medford, Oregon. Total tree biomass, N content, and ¹⁵N evaluations suggest that young pears require little N (48 kg N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was remobilized into new...

Creator:: Strausz, Stanley Douglas
Abstract:: This investigation was undertaken to observe possible changes in growth substances in Pyrus throughout the dormant period. The primary objective was to determine if a correlation existed between growth substance content and the inherent chilling requirement of seeds and buds. Samples of whole buds were taken at intervals from the...
