Abstract Pears (Pyrus) are one of the most economically important fruits worldwide. The Pyrus genus is characterized by a high degree genetic variability between species and interspecific hybrids, several studies have been performed to assess this for both cultivated wild accessions. These mostly limited resolving power traditional molecular markers, although in recent past availability referen...

background: the mechanism of hypoglycemic and hypolipidemic activities of pyrus biossieriana buhse leaf extract (pbble) and its phytochemical component arbutin, have not been well determined. the present study was performed to understand the hypoglycemic activity mechanisms of pbble and arbutin more clearly.methods: in vitro enzymatic carbohydrate digestion with pbble and arbutin was assessed u...

The nutritional value of the peeled and unpeeled fruit (peel plus flesh tissues) was studied using four peach (Prunus persica L.; Red Heaven, Maria Blanca, Big Top, Queen Giant), two pear (Pyrus communis Santa Maria, Pyrus pyrifolia N.; Nashi), three apple (Malus domestica Borkh.; Gala, Granny Smith, Chief) cultivars. Based on principal components analysis (PCA) models, there a clear differenti...

Pear psylla (Cacopsylla pyricola Foërster) is the most serious pest of the European pear (Pyrus communis L.) in the production regions of Europe and North America. Nine plant germplasm introductions of pear from Central Europe recently released from plant quarantine were evaluated for nymphal feeding antixenosis, a primary mode of resistance known to be correlated with ovipositional antixenosis...
