Abstract The objective of this study is to describe the agronomic attributes SCS443 Isadora apple tree cultivar and highlight its potential use in Brazil. Obtained by hybridization made at Epagri 2001 between ‘Imperatriz’ ‘Cripps Pink’, after 20 years evaluations carried out Caçador-SC Fraiburgo-SC, ‘SCS443 Isadora’ was originated. This has a wide plasticity adaptation southern Brazilian climat...

The partial compositional characteristics were determined for apple juice from 175 non-commercial varieties of apples developed from scion wood collected from approximately 12 countries and several USA geographical areas. Juices from many of the varieties were high in malic acid and potassium. Mean values for many of the attributes did not match existing compositional database value means. Howe...

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is a highly destructive pest of onion, Allium cepa L., and its management relies on multiple applications of foliar insecticides. Development of insecticide resistance is common in T. tabaci populations, and new strategies are needed to relax existing levels of insecticide use, but still provide protection against T. tabaci without...

A range of possible substitutes for copper-based fungicides for control of apple scab (Venturia inaequalis) in organic growing were tested in laboratory and growth chamber experiments in the Danish project StopScab (2002-2004). Eighteen crude plant extracts, 19 commercial plant-based products and 6 miscellaneous compounds were tested for their ability to reduce scab symptoms on apple seedlings....

Atomic force microscopy (AFM) and Fourier transformation infrared (FT-IR) spectroscopy was used for assessment of structural differences of celluloses of various origins. Investigated celluloses were: bacterial celluloses cultured in presence of pectin and/or xyloglucan, as well as commercial celluloses and cellulose extracted from apple parenchyma. The crystallinity index (XC%) varied from 25 ...

Abstract Phenolic compounds in apples 17 cultivars ( Malus domestica Borkh.) and 3 wild forms sp.) were analyzed to study the impact of genetic background, growth site, fruit bagging. The altitude was studied nine by analyzing fruits collected from orchards at three altitudes. Procyanidin B2 (71–628 μg/g fresh weight), −)-epicatechin (35–357 μg/g), chlorogenic acid (28–563 μg/g) always most abu...

Fruit development in higher plants normally requires pollination and fertilization to stimulate cell division of specific floral tissues. In some cases, parthenocarpic fruit development proceeds without either pollination or fertilization. Parthenocarpic fruit without seed has higher commercial value than seeded fruit. Several apple (Malus domestica) mutants (Rae Ime, Spencer Seedless and Welli...

Apples are an important component of the diet and used in food industry production products beverages. The aim study was to determine changes biochemical composition physicochemical properties apples stored a controlled atmosphere. We studied (sugars, ascorbic acid, soluble solids, titratable acidity) (color coordinates, peel, flesh firmness) apple samples before placing them atmosphere chamber...
