Cell walls from flesh, parenchyma cells, stone cells and skin were isolated from ripe and overripe Pyrus communis L. cv "De Cloche" using the phenol-buffer method. Pear polysaccharides were solubilized from cell walls by sequential extractions with aqueous solutions of ammonium oxalate, Na2CO3, and increasing concentration of NaOH, to explore overripening impact. Cell walls were also differenti...

Herein, we report on the results of solventand sorbent-free HS-GC-MS (headspace – gas chromatography – mass spectrometry) analysis of the headspace volatiles (HSVs) of fruits of cultivated melon (Cucumis melo L. cultivar “ananas dinja” [pineapple melon]) and pear (Pyrus communis L. cultivar “Julska lepotica” [the beauty of July]), as well as of underground parts of carrot (Daucus carota L. cult...

Plant cell suspension cultures are widely used for the production of recombinant proteins and secondary metabolites. One of the most important steps during process development is the optimization of yields by testing different cultivation parameters, including the components of the growth medium. However, we have shown that the biomass yield of a cell suspension culture derived from the pear cu...

Bu çalışma, armut ağaçlarının bulunduğu topraklarda çeşitli bor fraksiyonlarının araştırılması amacıyla yapılmıştır. amaçla Türkiye'nin Bursa yöresindeki “Deveci” ve “Santa Maria” (Pyrus communis L.) bahçeleri ziyaret edilmiştir. Toprak örnekleri 0-30 cm 30-60 den alınmıştır. Ayrıca meyve yaprak numuneleri de toplanmıştır. Toplam toprak boronunun en büyük oranı kalıntı formda (% 94.28-94.51) me...

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...

Pyrus calleryana was intentionally introduced to North America from east Asia in the early 1900s as rootstock for edible pear tree, communis. It identified an ideal decorative, agricultural, and horticultural tree because of its small stature, spring flowering, fire blight resistance inoffensive fruits. P. escaped cultivation is now considered invasive species, typically found on roadsides, pra...
