| Abstract The plant genes encoding ABCGs that have been identified to date play a role in suberin formation in response to abiotic and biotic stress. In the present study, 80 ABCG genes were identified in ‘Dangshansuli’ Chinese white pear and designated as PbABCGs. Based on the structural characteristics and phylogenetic analysis, the PbABCG family genes could be classified into seven main groups: classes A-G. Segmental and dispersed duplications were the primary forces underlying the PbABCG gene family expansion in ‘Dangshansuli’ pear. Most of the PbABCG duplicated gene pairs date to the recent whole-genome duplication that occurred 30~45 million years ago. Purifying selection has also played a critical role in the evolution of the ABCG genes. Ten PbABCG... |

| The objective of this paper is to describe different types of value chain, to capture value added activities of each chain, to discuss the organizational and institutional link in each value chain and its implications for the role of small farmers. We focus on two counties in Hebei and Zhejiang of China. Taking pear for example, analysis of value chain is conducted using data of representative samples of pear value chain. For each chain, value added activities, cost composition, profit distribution, organizational and institutional linkages are illustrated, and corresponding conclusions are indicated. After a systematic analysis of organizational and institutional linkage and value adding activities of every chain as well as cost-benefit analysis of... |

| Harmonia axyridis was detected for the first time in Brazil in 2002. Since then, it has been recorded from the South to the Midwest of the country. Until now, almost all the registered cases were associated with the presence of aphids, its preferred source of food. Due to the occurrence of this species in areas of fruit growing in the South and Southeast of Brazil, the aim of this study was to analyze the preference and use of three different cultivars of fruit. The tests were set at 25ºC ± 1ºC, RH 70% ± 10%, and in a photophase of 12 h and with apples (Gala and Fuji), grapes (Niágara and Rubi), and pears (Williams and Asian). In the undamaged fruit experiment, the insects did not cause any noticeable damage. In the damaged and undamaged fruit experiment,... |

| ABSTRACT The new SCS421 Carolina cultivar, belonging to the Pyrus pyrifolia var. culta species, is classified as an Asian pear type or more specifically Japanese pear type. It was obtained from the Kousui x Osanijisseiki crossing made at Epagri / Caçador Experimental Station. Its flowering occurs from the second half of September to mid-October, similarly to Housui cultivar. According to preliminary results, ‘Yali’ and ‘Housui’ may be used as pollinators. The harvest takes place in the first half of February and production is above 20 t / ha. Plants produce more rounded and symmetrical fruits compared to Housui cultivar. The fruit skin is golden, the pulp is crispy, soft, sweet, very juicy and slightly aromatic. Fruits can be stored for up to four months... |

| Pear (Pyrus communis), which is intensively cultivated in subtropical and temperate climates, has recently attained the 3rd position in the world fruit ranking, just after apple and peach. This fruit exhibits certain similarities to apple with respect to the pulp, but pear is used as a raw material only when apple is no longer available, which suggests that the same technology line may be utilized. Both fruits do have processing compatibilities, and it is permissible to add pear juice to apple juice at levels defined by law. Quality indicators, such as pH, total acidity, total phenolic compounds and antioxidant activity were used. The simple sugar analysis clearly defines fructose as the main component in pear juice, and lower figures were found when... |

| Recently, non-destructive techniques such as the Vis / NIR spectroscopy have been used to evaluate the characteristics of maturation and quality of pears. The study aims to validate the readings by the Vis / NIR spectroscopy as a non-destructive way to assess the qualitative characteristics of pear cultivars 'Williams', 'Packams' and 'Carrick', produced according to Brazilian conditions. The experiment was conducted at the Pelotas Federal University, UFPel, in Pelotas / RS, and the instrument used to measure the fruit quality in a non-destructive way was the NIR- Case spectrophotometer (SACMI, Imola, Italy). To determine pears' soluble solids (SS) and pulp firmness (PF), it was established calibration equations for each variety studied, done from the... |
