Exploration of a plant architecture database with the AMAPmod software illustrated on an apple tree hybrid family

چکیده
This paper describes the constitution and the statistical exploration of a plant architecture database using the AMAPmod system. In AMAPmod, plant architectures are represented by a formal model, called MTG, which is the central data structure of the system. A dedicated querying language AML enables the user to access plant architecture data with efficient built-in primitives. By combining these primitives, the user can extract various types of data that preserve a more or less important part of the structural information of the plant. Specific statistical tools have been designed to analyse data samples extracted from the plant architectures. Most of these tools, ranging from (hidden) Markovian models to dynamic programming comparison techniques, apply to samples of sequences. AMAPmod methodology is illustrated on an actual-scale example concerning a hybrid family of apple trees. (© Inra/Elsevier, Paris.)

Ce papier décrit la constitution et l’analyse statistique d’une base de données contenant des descriptions d’architectures de plantes à l’aide du système AMAPmod. Dans AMAPmod, l’architecture des plantes est représentée par un modèle formel, nommé MTG, qui constitue la structure de données centrale du système. Un langage d’interrogation dédié, AML, permet à l’utilisateur d’accéder aux architectures des plantes à l’aide de primitives spécialisées et efficaces. En combinant ces primitives, des types de données variés permettant de préserver une part plus ou moins grande de l’information structurelle contenue dans la plante peuvent être extraits de la base de données. Des outils spécialisés ont été créés pour analyser les échantillons de données ainsi constitués. La plupart de ces outils, tant paramétriques (modèles markovien variés) que non paramétriques (algorithmes de comparaison de données fondés sur des techniques de programmation dynamique) s’appliquent à des séquences de données.

Effects of Sulfur Application on Soil pH and Uptake of Phosphorus, Iron and Zinc in Apple Trees
The main reasons for the fixation of some elements and consequently nutrient deficiencies, especially phosphorus, iron and zinc, are high levels of calcium (calcareous soils) and soil pH. Two sulfur fertilizers (sulfur alone and sulfur + organic material + Thiobacillus spp.) with two rates (2 and 4 kg sulfur/tree) were used to decrease soil pH and availability of P, Fe and Zn in apple trees dur...
متن کاملFloradig: a configurable program for capturing plant architecture
Floradig is computer software for measuring and recording plant architecture and how it changes over time. It is generic in that it can be configured to collect plant architecture data for any species of plant at any level of detail. It uses a systematic, hierarchical, approach to address the modular nature of plants in which complex architectures are constructed from limited sets of components...

متن کاملInvestigating the effects of climate change on the pattern of heat accumulation in apple trees cultivation areas in Iran during the future period
Climate change stand as the most important challenge in the future. Horticulture is one of the most sensitive and vulnerable sectors to the climate change. Climate change and global warming will endanger the production of agricultural products and food security. Because of required longer time to fruit production, fruit trees are heavily susceptible to damage from climate change. The purpose of...
