Tomato wild relatives are important sources of resistance to many pests cultivated tomato [Solanum lycopersicum L. (syn. Lycopersicon esculentum Mill.)]. Eleven accessions previously identified at AVRDC—The World Vegetable Center as resistant Bemisia tabaci were evaluated for the two-spotted spider mite [Tetranychus urticae (Koch.)] based on egg numbers using leaf disc and Tanglefoot no-choice bioassays, damage scores in choice bioassays. Highest bioassays was AVRDC S. galapagense VI057400,...
Despite previous reports on the genotypic variation of architectural and functional traits in fruit trees, phenotyping large populations field remains challenging. In this study, we used high-throughput methods an apple tree core-collection (1000 individuals) grown under contrasted watering regimes. First, was achieved using T-LiDAR scans for estimating convex alpha hull volumes silhouette to total leaf area ratio (STAR). Second, a semi-empirical index (IPL) computed from chlorophyll...
Genetic studies of response to water deficit in adult trees are limited by low throughput the usual phenotyping methods field. Here, we aimed at overcoming this bottleneck, applying a new methodology using airborne multispectral imagery and planta measurements compare high number individuals. An apple tree population, grafted on same rootstock, was submitted contrasting summer regimes over two years. Aerial images acquired visible, near- thermal-infrared three dates each year allowed...
ISHS I International Symposium on Horticulture in Europe DOES KNOWLEDGE ON FRUIT TREE ARCHITECTURE AND ITS IMPLICATIONS FOR ORCHARD MANAGEMENT IMPROVE HORTICULTURAL SUSTAINABILITY? AN OVERVIEW OF RECENT ADVANCES IN THE APPLE
Tree architecture shows large genotypic variability, but how this affects water-deficit responses is poorly understood. To assess the possibility of reaching ideotypes with adequate combinations architectural and functional traits in face climate change, we combined high-throughput field phenotyping genome-wide association studies (GWAS) on an apple tree (Malus domestica) core-collection. We used terrestrial light detection ranging (T-LiDAR) scanning airborne multispectral thermal imagery to...
Genomic selection (GS) is a breeding approach which exploits genome-wide information and whose unprecedented success has shaped several animal plant schemes through delivering their genetic progress. This the first study assessing potential of GS in apricot (Prunus armeniaca) to enhance postharvest fruit quality attributes. predictions were based on F1 pseudo-testcross population, comprising 153 individuals with contrasting traits. They phenotyped for physical biochemical metrics climatic...
Water use efficiency (WUE) is a quantitative measurement which improvement major issue in the context of global warming and restrictions water availability for agriculture. In this study, we aimed at studying variation genetic control WUE respective role its components (plant biomass transpiration) perennial fruit crop. We explored an INRA apple core collection grown phenotyping platform to screen one-year-old scions their accumulated biomass, transpiration under optimal growing conditions....
It is generally postulated that at the tree scale a drought-related decrease in hydraulic conductance balanced by of leaf area. We hypothesized that, individual scale, drought affects allometry between area or mass and hydraulics, leading to non-linear relationships these traits. The study was conducted on well-watered water-stressed shoots several apple genotypes covering an extended range Working dried leaves, we measured lamina analyzed their with maximal xylem water pathway through...
• Background and Aims In several species exhibiting a rhythmic aerial growth, the existence of an alternation between root shoot growth has been demonstrated. The present study aims to investigate respective involvement emergence new organs their elongation in relation this phenomenon its possible genotypic variation young apple plants. Methods Two varieties, X6407 (recently named ‘Ariane’) X3305 (‘Chantecler’ × ‘Baujade’), were compared. Five plants per variety, issued from vitro culture,...
Fruiting and nonfruiting `Washington' peach trees were grown in 2.4 (small) or 9-liter (large) containers to determine the influence of root confinement fruiting on vegetative growth, fruit growth quality, CO, assimilation (A), carbohydrate content. Shoot length, diameter, A, leaf carbohydrates measured weekly. Thirteen weeks after transplanting, divided into roots, shoots, leaves, for dry weight measurement. The all organs except was reduced by confinement, only stems formed previous season...
Temporal and spatial variations of photosynthesis transpiration are particularly important when considering vegetative growth fruit variability in trees. Spatial variation physiological processes depends on light distribution, which turn the relative position main branches geometry their foliage. The general aim this research was to investigate capacity RATP (radiation absorption, transpiration, photosynthesis) functional-structural model adequately simulate within-tree behavior fruiting at...

The aim of this study was to estimate water flux apple tree branches, from measurements transpiration and stomatal conductance, made at the leaf scale. For purpose, we used model RATP (Radiation Absorption, Transpiration Photosynthesis) which simulates spatial distribution solar radiation leaf-gas exchange within crowns as a function canopy structure, microclimate physical physiological properties. In present application, one-hour time steps outputs were compared with field measurements....
