As one of the Ca2+ sensors, calcium-dependent protein kinase (CPK) plays vital roles in immune and stress signaling, growth and development, and hormone responses, etc. Recently, the whole genome of apple (Malus × domestica), pear (Pyrus communis), peach (Prunus persica), plum (Prunus mume) and strawberry (Fragaria vesca) in Rosaceae family has been fully sequenced. However, little is known abo...
Vegetative propagation of pear rootstocks using semi hardwood cuttings The objective of this work was to evaluate the technical viability of the vegetative propagation of the pear rootstocks ‘Taiwan Nashi-C’, ‘Taiwan Mamenashi’ (Pyrus calleryana Dcne.) and ‘Seleção IAC-1’ (Pyrus spp.) using semi-hardwood cuttings. The experiment was conducted in a nursery with an intermittent mist system at the...
We have used new generation sequencing (NGS) technologies to identify single nucleotide polymorphism (SNP) markers from three European pear (Pyrus communis L.) cultivars and subsequently developed a subset of 1096 pear SNPs into high throughput markers by combining them with the set of 7692 apple SNPs on the IRSC apple Infinium® II 8K array. We then evaluated this apple and pear Infinium® II 9K...
AIM: The present study aims to investigate for the first time antitumor and antibacterial activities of Viscum album L. grown on different host trees. METHODS: Two different bioassays (antitumor and antibacterial) were performed to evaluate the biological activities of European mistletoe (Viscum album L.) plants collected from 13 different host trees (Crataegus tanacetifolia, Crataegus monogyna...
Once, Europe was one large natural area, across which species of animals and plants were able freely to move and disperse. Today, a satellite image of Europe looks like a Persian carpet cut into millions of small rectangular pieces, each fashioned by the plough and the spade over thousands of years of cultivation. The consequence of this change is that species have disappeared. For example, ani...
Crotches were cut out of red maple (Acer rubrum), callery pear (Pyrus calleryana), and sawtooth oak (Quercus acutissima) trees (2.5”-7” d.b.h.) and then pulled apart in an engineering testing machine to identify physical parameters correlated with crotch strength. Parameters measured included the diameter of the branch and of the trunk above and below the crotch, angle of the branch and branch ...
The disease brown spot of pear (Pyrus communis L.) (BSP) is caused by the fungus Stemphylium vesicarium (Wallr.) E. Simmons. The economical losses caused by BSP are very important in several pear production areas of Europe including Spain, Italy, France, Portugal, The Netherlands and Belgium (Llorente and Montesinos, 2006). Control of BSP is based on fungicide applications during the growing se...
Despite the increasing interest in organic products, knowledge about how different levels of fertilization affect nutritionally relevant components is still limited. The concentration of polyphenols and the activity of polyphenoloxidase (PPO), together with the content in ascorbic acid, citric acid, and alpha- and gamma-tocopherol, were assayed in conventional and organic peach (Prunus persica ...
گلابی (pyrus communis l.) همانند بسیاری دیگر از درختان میوه خانواده گلسرخیان دارای خودناسازگاری گرده بوده و برای باردهی مناسب نیازمند وجود ارقام گرده زای سازگار است. این تحقیق با هدف شناسائی گرده زای مناسب برای ارقام تجارتی بومی گلابی انجام شد. به این منظور طی دو سال متوالی، تلاقی های دوطرفه بین ارقام گلابی شاه میوه، شکری، نطنزی، سبری و درگزی از ارقام بومی و بارتلت انجام و میزان تشکیل میوه، بذر...
