Maximizing and minimizing pear (Pyrus sp.) chimeral segregation in vitro
A protocol has been developed for maximizing and minimizing chimeral segregation in vitro of three periclinal pear chimeras ('Louise Bonne Panachee' (p1092) ('LB'); 'Red Hardy' ('RH'); 'Red Comice' ('RC'). Among the factors involved in chimeral stabilization and segregation were growth regulators …

Studio molecolare dei meccanismi dell'autoincompatibilità gametofitica in pero europeo (Pyrus communis)
… the molecular mechanism of GSI in European pear (Pyrus communis) as well as in the other Pyrinae; it was divided in two parts, the first focusing on the characterization of male determinants, and the second on factors external to the S locus. The research of S locus F-box genes was primarily aimed …

The genetic determinants of vigour control and precocity by pear (Pyrus communis L.) rootstocks
… cultivars. Currently there is a lack of Pyrus rootstocks that are vigour-controlling and precocity-inducing. The development of such a rootstock is a major focus in pear rootstock breeding. Marker assisted selection (MAS) could help to shorten this time consuming and costly breeding …

Development of microsatellite (SSR) marker multiplexes for future construction of a genetic linkage map for pear (Pyrus communis L.)
… includes fruit species such as pear. Pears (Pyrus communis L.) are large edible fruit that are grown in cool climates, native to coastal regions in Africa, Asia and Europe. The external appearance of this fruit plays a vital role on its rate of sale potential. Thus it is important for the …

ΣΥΜΒΟΛΗ ΣΤΗΝ ΠΕΙΡΑΜΑΤΙΚΗ ΜΕΛΕΤΗ ΔΙΟΥΡΗΤΙΚΗΣ ΔΡΑΣΗΣ ΦΥΤΙΚΩΝ ΔΡΟΓΩΝ (PSIDIUM GUAVA, AGROPYRUM REPENS, PYRUS COMMUNIS). ΧΗΜΙΚΗ ΑΝΑΛΥΣΗ ΤΩΝ ΣΥΣΤΑΤΙΚΩΝ ΦΥΛΛΩΝ ΤΟΥ ΦΥΤΟΥ PSIDIUM GUAVA
… DIURETIC EFFECT ON RATS OF PSIDIUM GUAVA LEAVES,PYRUS COMMUNIS LEAVES, AND AGROPYRUM REPENS ROOTS IS STUDIED. MALE ALBINO WISTAR RATS (N=480) AGED FROM 70 TO 90 DAYS, WEIGHING 270 G WERE USED. ACCORDING TO THE TREATMENTS, GIVEN PER OS (3 ML/100 G B.W), THEY WERE DIVIDED INTO THE FOLLOWING GROUPS: …

Structural Features Related to Tree Crotch Strength
… out of red maple (Acer rubrum), callery pear (Pyrus calleryana), and sawtooth oak (Quercus acutissima) trees (2.5â -7â 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 …

Characterization of Polymorphic Microsatellites in Strawberry and Their Transferability to Other Genera in the Rosaceae Family
… for UDF-018 showed that three species, i.e., Pyrus calleryana, Prunus persica and Rubus idaeus contained the expected microsatellite whereas another four, i.e., Cotoneaster salicifolius, Rosa rugosa, Amelanchier arborea and Potentilla fruticosa had conserved regions resulting in generation of …

Estimation of the genetic parameters of boron and sorbitol concentration in fruit from a pear breeding population, and investigation of the relationship between these traits on the occurrence of flesh spot decay
Pears (Pyrus spp.) are among the oldest crops grown worldwide. They are cultivated in all temperate regions and world production is second only to apples among deciduous tree fruits. Flesh spot decay (FSD) is one of the most important physiological disorders of Asian pears. The causes of this …

Vegetation management along roadside and railroad right-of-ways
… roadside ROW's was determined. Callery pear (Pyrus calleryana) has escaped cultivation and invaded undisturbed areas such as roadsides and pastures from the mid-west to eastern United States. Experiments were initiated in 2015-2017 to determine the response of herbicides delivered by foliar, …

SSR-based genetic mapping of QTLs determining chilling requirements for time of initial vegetative budbreak in domesticated apple (Malus x domestica Borkh.) cultivar ‘Anna’ x ‘Austin’
… (Prunus persica L. Batsch) and European pear (Pyrus communis L.). However, despite its evident economic importance, it is generally poorly studied in genomic terms, relative to the other major crop groups. Microsatellite and Diversity Array Technology (DArT) genetic markers have been exploited …

Elucidation of the Function of Dihydrochalcones in Apple
… intergeneric hybrid between M. x domestica and Pyrus communis L. known to accumulate intermediate levels of DHCs compared to apple, in order to identify additional genes potentially involved in DHC pathway. We compared the physiological effect of reducing phloridzin through PGT1 knockdown by …

Salt stress responses in pear and quince: physiological and molecular aspects
… lands. Like almost all the fruit tree species, Pyrus communis is generally considered a salt sensitive species, but only little information is available on its behavior under saline conditions. Previous studies, carried out in the Department of Fruit Tree and Woody Plant Science (University of …
