Optimization of Bonus-Malus Systems
Bonus-Malus System (BMS) is a risk managing method mostly used in liability insurances. The most general application of the BMS is in the Motor third-party liability insurance. In a BMS, there are finitely many classes, each having a different premium. At the start of the contract, each …

Untersuchungen zur Regulation der Flavonoidbiosynthese im Kulturapfel Malus x domestica
In contrast to many other plants where biosynthesis of flavonoids and regulation of the involved genes is well analyzed, only little is known in the cultured apple M. x domestica about this pathway. Although most important intermediates and their structural genes are identified, regulation and the …

Variabilidad genética en germoplasma argentino de manzano silvestre (Malus spp)
El manzano (Malus x domestica Borkh.) es una de las especies frutícolas más importantes y Argentina es uno de los principales productores de manzanas del hemisferio sur. Desde su origen, en el centro de Asia, ha experimentado una gran expansión y selección, producto de los objetivos de agricultores …

Characterization of malus germplasm and QTL mapping of fruit quality traits
… important to obtain knowledge of the genetics of Malus in order to efficiently maintain genetic diversity, as well as breed and select future apple cultivars. Germplasm characterization can reveal knowledge of genetic relatedness of accessions and is important towards the goal of increasing this …

Unraveling Molecular Mechanisms Regulating Dormancy and Bloom Time in Apple (Malus × domestica Borkh)
Bud dormancy is an essential characteristic of deciduous woody perennials, including apple, to cope with the low temperatures during winter. The release from dormancy and subsequent budburst in apple can only occur after fulfillment of chilling and heat requirements. In the Mid-Atlantic region, …

Laboratory evaluation of some Malus cultivars and hybrids to attack by pine voles
… the resistance of one-year-old stems of 111 Malus rootstock cultivars and hybrids to pine vole damage. The tank fest proved to be an excellent method for: testing several clones at one time; providing the animals with more of a natural environment; exposing all animals to each stem in the …

Cytokinins tolerance and in vitro selection for dwarfism in apple (Malus x domestica Borkh.)
… was developed for leaf segments of six apple (Malus Xdomestica Borkh) cultivars ('Wijcik', 'McIntosh', 'Macspur', 'Regal Gala' and 'M 26') grown in vitro using modified Murashige and Skoog (MS) medium supplemented with N-phenyl-N$\sp\prime$ 1,2,3,-Thidiazuron (TDZ). TDZ was found superior to …

Investigation of Regulatory Mechanisms of Chemical-Mediated Fruit Thinning in Apple (Malus X Domestica Borkh.)
… were examined in "Golden Delicious" apples (Malus x domestica borkh.). NAA at 15 mg·L-1 and shading increased fruit abscission and ethylene production of leaves and fruit when applied at a 12-mm stage of fruit development, whereas AVG, an inhibitor of ethylene biosynthesis, at 250 mg·L-1 …

MicroRNAs and Trans-acting siRNA pathways in Apple (Malus x domestica Borkh.) and Peach (Prunus persica)
The unveiling of small RNA (sRNA)-mediated gene regulatory pathways has profoundly shaped our understanding of the complexity of gene regulation. In eukaryotes, sRNAs have been found to control cellular metabolism, growth and differentiation, to maintain genome integrity, and to combat viruses and …

Sensor based determination of the fruit bearing capacity in Malus x domestica (Borkh.) aimed at precise crop load management
One major goal of commercial fruit production is a homogenous fruit quality throughout the whole orchard. For this purpose, crop load management practices in apples intend to reduce the number of fruit per tree in order to (i) optimise the carbon supply to demand balance and the (ii) fruit quality …

Fungicidal control and related studies on black root rot of apple (Malus pumila Mill.) caused by xylaria mali Fromme
Attempts were made to control black root rot of apple with the fungicides, benomyl, captan, thiabendazole and triarimol, and to determine their fungitoxic effects on the causal pathogen Xylaria mali. The pathogen responded differently in various bioassay methods, but all fungicides were inhibitory …

The Use of Tissue Culture to Separate Apple (Malus Sp.) Chimeras Into Their Constituent Genotype(s) and to Induce Anthocyanin Production
To assess somaclonal variation, 'Gala', 'Royal Gala' and 'Jonagold' trees obtained via axillary and adventitious bud formation were compared ex vitro to conventionally grafted trees. In general, tissue culture-derived trees were relatively erect and their branch angles were relatively narrower in …

Development of a pre-selection index for cider apple (Malus x domestica Borkh.) genotypes by phenotyping a low-chill requiring red-fleshed breeding progeny
ENGLISH ABSTRACT: The rapid growth of the cider industry in South Africa, coupled with wine grape producers in warmer regions seeking diversification options, led to the concept of developing low-chill, red-fleshed cider apples to support both industries. The low-chill trait allows apples to be …

Interaction Between Insects and Apple (Malus X Domestica Borkh.): Insect Behavior, Genotypic Preference, and Plant Phenolics With Emphasis on Japanese Beetle (Popillia Japonica Newman)
Leaves and fruit of nine apple (Malus x domestica Borkh.) genotypes were evaluated for insect injury in 1998 and 1999. Foliar and fruit injury from 12 insect species was inconsistently affected by genotype. Spraying trees with oil affected neither fruit insect injury nor fruit phytotoxicity. In …

Pollen Tube Growth Characteristics of Selected Crabapple Cultivars and Managing Apple (Malus x domestica) Crop Load and Early Season Diseases with Organic Bloom Thinning Chemicals
Reducing apple (Malus x domestica Borkh.) crop load during bloom is a reliable option for increasing fruit quality and return bloom. In this thesis, multiple approaches to improving bloom thinning practices are discussed. The first project analyzed the pollen tube growth of several crabapple …

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’
… temperate crops such as the domesticated apple(Malus x domestica Borkh.), peach (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. …
