Résistance aux inhibiteurs de l’ALS chez le séneçon commun (Senecio vulgaris) : la situation en vigne et en grandes cultures
2016
Resistance to ALS-inhibiting herbicides in common groundsel (Senecio vulgaris) : situation in franch vineyards and major field crops. Common groundsel (Senecio vulgaris) is a ubiquitous weed that is highly mobile and which seeds can germinate almost all year long. It also is the only weed species today in France that is officially acknowledged to have evolved a resistance to one same herbicide mode of action both in vineyards and major field crops. The purpose of this paper is to provide a picture of a few major aspects of this resistance: underlying mechanisms, detection, seed viability, spread and geographical extent of the resistance.
Fundamentals of Precision Agriculture
2023
Precision agriculture or precision farming is the targeted application of crop input according to the locally determined crop needs. Therefore, it is the geo-referenced application of crop inputs, whose rates should be those required by the crop. The most essential points of information about the topic being described are: overview; brief history of precision agriculture; theoretical basics of precision agriculture; precision agriculture cycle; geo-referenced measurement of within-field parameters; analysis and interpretation of geo-referenced data for mapping within-field parameters; spatially variable rate application of crop inputs; instruments for precision agriculture; current scenario…
Leaf spray with Ti(IV) ascorbate improves the iron uptake and iron activity in Capsicum annuum L. plants
1995
Leaves of paprika pepper (Capsicum annuum L., cv Negral) plants sprayed with Ti(IV)-ascorbate showed an important increase of iron and titanium concentrations, as well as of the activity of peroxidase and catalase enzymatic systems. Leaf-Ti increase is similar for both greenhouse and field crop experiments, but increases in leaf Fe are more marked in plants growing under field conditions.
Effects of arbuscular mycorrhizal symbiosis on nitrogen dynamics in Mediterranean agro-ecosystems
2010
Le simbiosi arbuscolo micorriziche (AM) sono formate dai funghi appartenenti al phylum Glomeromicota e piante superiori. Le simbiosi (AM) sono caratterizzate dalla penetrazione attiva del fungo dentro negli spazi intercellulari della cortaccia radicale e dalla formazione di strutture di scambio (chiamate ‘arbuscoli’) all’interno della parere cellulare. Gli arbuscoli sono strutture ramificate formate dal fungo AM all’interno della cellula vegetale invasa e sono indubbiamente gli organi chiave della simbiosi. Durante la loro formazione, la cellula vegetale si trasforma radicalmente. In particolare, la membrana cellulare si invagina e una membrana periarbuscolare con una ampia superficie di sc…
