به منظور ریزازدیادی چهار پایة پر رشد گلابی شامل پایههای کنجونی، Pyrus betulifolia، درگزی و پایة Gh1 اثر چند محیط کشت پایه (MS، QL و QL تغییریافته)، سایتوکینین و اکسین بر میزان باززایی، پرآوری و ریشهزایی آنها در شرایط درون شیشهای در مؤسسة تحقیقات اصلاح و تهیة نهال و بذر کرج بررسی شد. نتایج نشان داد در بین محیطهای کشت پایه، بیشترین میزان پرآوری برای همة پایهها، در محیط کشت QL مشاهده شد. ...
With regard to the importance of antioxidants in foods, cosmetics and pharmaceutics, there are several studies on natural resources for finding rich sources of antioxidants and their role in protecting the body against oxidative stress injuries. The purpose of this study was to investigate the antioxidant stability of arbutin and the Pyrus boissieriana buhse Leaf extract and their effects on li...
Prunus and Pyrus species affected with phytoplasma diseases, as well as leafhopper species collected from Prunus and Pyrus fields in Ontario, Canada were tested for presence of phytoplasmas. Preliminary results showed that Graminella nigrifrons is a potential vector for phytoplasma groups 16SrI-W (‘Candidatus Phytoplasma asteris’), and 16SrVII-A (‘Candidatus Phytoplasma fraxini’) to a variety o...
The Pyrus species exhibit the gametophytic self -incompatibility which is considered to be the most widespread self-incompatibility system among flowering plants. This system prevents self-fertilization through a specific pollen-pistil recognition mechanism. The S-allele diversity in the Iranian genotypes indicates that the pear germplasm of Iran can be an excellent source of variability for br...
Bud exudates from twelve clones o f Populus nigra originating from seven countries were analyzed by gas chromatography-mass spectrometry and the principal compounds identified. Specimens o f P. nigra var betulifolia differed in bud exudate composition from the other speci mens analyzed, and were more similar in exudate composition to P. deltoides than were the other specimens. The range o f bu...
We developed retrotransposon-based insertional polymorphism (RBIP) markers based on the long terminal repeat (LTR) sequences of copia-like retrotransposon Ppcrt4 and flanking genome sequences, which were derived from 454 sequencing data from Japanese pear (Pyrus pyrifolia) 'Hosui'. Out of 40 sequences including both LTR and flanking genome regions, we developed 22 RBIP markers and used them for...
