Self-incompatibility is considered to be a growth limiting factor in fruit plants. In species with hermaphrodite flowers, S-locus (S-allele) has been accepted control self-incompatibility, and the genetic of this locus provided by multiple genes (alleles). Pear (Pyrus communis L.) belongs Pomoideae from Rosaceae family found have great potential terms ecological features Turkey. To protect thes...

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.

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...

Defense elicitors are products that activate acquired defense responses in plants, thus rendering the plants less susceptible to attack by a broad range of pests. We demonstrated previously under laboratory conditions that foliar applications of the defense elicitors Actigard (acibenzolar-S-methyl), Employ (harpin protein), or ODC (chitosan) to potted pear trees (Pyrus communis L.) each caused ...

Some local cultivars and wilds of Iwateyamanashi (Pyrus ussuriensis var. aromatica) that grows wild in Northern Tohoku, Japan have good aromatic fruit. Iwateyamanashi may be valuable germplasms as a donor of odor compounds in breeding of Japanese pear (Pyrus pyrifolia), because almost all Japanese pear cultivars have faint odor. Fruits odors from a local cultivar 'Sanenashi', a wild accession (...
