Marino, P., Schicchi, R., Barone, E., Raimondo F. M. & Domina G.: First results on the phenotypic analysis of wild and cultivated species of Pyrus in Sicily. — Fl. Medit. 23: 237-243. 2013. — ISSN: 1120-4052 printed, 2240-4538 online. Phenotypic analysis of Pyrus in Sicily using a set of 19 characters on 71 accessions belonging to 7 species is here reported. Results show a high level of morphol...
رشد در گیاهان به مفهوم افزایش غیر قابل برگشت در حجم و وزن می باشد که براساس مرحله و زمان رشد، میزان فعالیت و نیازهای فیزیولوژیکی درخت متفاوت است. پژوهش حاضر به منظور تعیین الگوی رشد میوه در طول دوره رشد و نمو میوه، تعیین مرحله بحرانی رشد میوه و برقراری رابطه ریاضی بین قطر با حجم و وزن میوه انجام گرفت. به منظور اجرای دو آزمایش مجزا، از 4 ژنوتیپ میان رس (ks13 و ka14) و دیررس (ks8 و ks12) گلابی ...
Cultured pear (Pyrus communis 1. cv Passe Crassane) cells were subjected to temperatures of 39,42, and 45°C. Heat-shock protein (hsp) synthesis was greater at 39'C than at temperatures above 40'C and continued for up to 8 h. Both cellular uptake of radiolabeled methionine and total protein synthesis were progressively lower as the temperature was increased. Polysome levels decreased immediately...
Genetic maps for two pear cultivars ‘Red Bartlett’ (Pyrus communis L.) and ‘Nanguo pear’ (Pyrus ussuriensis Maxim.) were constructed using SRAP molecular markers. The mapping population consists of 74 F1 individuals derived from the cross of a cultivar ‘Red Bartlett’ with good fruit quality as the female parent and a cultivar ‘Nanguopear’ with good cold tolerance as the male parent. Linkage map...
We present a draft assembly of the genome of European pear (Pyrus communis) 'Bartlett'. Our assembly was developed employing second generation sequencing technology (Roche 454), from single-end, 2 kb, and 7 kb insert paired-end reads using Newbler (version 2.7). It contains 142,083 scaffolds greater than 499 bases (maximum scaffold length of 1.2 Mb) and covers a total of 577.3 Mb, representing ...
The Ussurian pear is the most important cultivated pear in the northern part of China. Cultivated Ussurian pears are considered to have derived from Pyrus ussuriensis Maxim. which is native to the northeast of China. In Japan, two varieties of P. ussuriensis, P. ussuriensis var. aromatica and var. hondoensis are native to the northern area and the central area of the main island respectively. I...
در این مطالعه، ساختارتشریحی برگ و دمبرگ 10 گونه ایرانی از جنس گلابی متعلق به چهار بخش Pashia , Pyrus, Xeropyrenia, Argyromalonبه همراه یک گونه کاشته شده نزدیک گونه Pyrus syriaca ارائه می شود. این گونه هاعبارتنداز: Pyrus kandevanica Gahreman & Khatamsaz, P. boissieriana Buhse, P. mazanderanica Schonbeck- Temesy, P. hyrcana Fedor, P. turcomanica Maleev, P. elaeagnifolia Pall., P. salicifolia P...
Establishing intensive plantations of fast growing hardwood tree species that have high market values in the forest industry can narrow the gap between Turkey's demand and the supply of quality hardwood products. Black cherry (P. serotina Ehrh.) is a fast growing hardwood species with a high market value. Introducing and intensively growing black cherry (BC) in Turkey may significantly reduce t...
The Middle Cambrian Spence Shale Member (Langston Formation) and Wheeler and Marjum Formations of Utah are known to contain a diverse soft-bodied fauna, but important new paleontological material continues to be uncovered from these strata. New specimens of anomalocaridids include the largest and smallest near complete examples yet reported from Utah. New material of stem group arthropods inclu...
