Abstract The influence of TDZ on adventitious shoot regeneration from leaves the pear cultivars Conference and Abate Fétel, rootstock Farold ® 87 was investigated. Our main aim to set up efficient in vitro protocols for all these genotypes by using expanding elongated cultures as starting plant material. best results terms percentage were achieved half-strength Murashige Skoog basal medium supp...

'Jin Zhui' is a spontaneous self-compatible mutant of 'Ya Li' (Pyrus bretschneideri Rehd. S21S34 ), the latter displaying a typical S-RNase-based gametophytic self-incompatibility (GSI). The pollen-part mutation (PPM) of 'Jin Zhui' might be due to a natural mutation in the pollen-S gene (S34 haplotype). However, the molecular mechanisms behind these phenotypic changes are still unclear. In this...

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...

Pears are among the most economically important fruits in world that grown all temperate zones. Pyrus communis L., ‘Pyrodwarf®(S)’ rootstock is one of gene sources used to improve fruit productivity, resistance, and tolerance biotic abiotic stresses. Traditional propagation P. L. time-consuming limited by a short growing season harsh winter conditions. Therefore, vitro suitable alternative. Mur...

The phenolic composition of the exocarp, hypanthium, and endocarp from three pear cultivars: Jingbai, Korla Crystal were measured by high-performance liquid chromatography method with diode array detection (HPLC-DAD), while antioxidant activities investigated using DPPH radical andABTS cation scavenging activity, FRAP. Ferulic acid, chlorogenic caffeic acid detected as major components. exocarp...
