Multiplication végétative in vitro des caféiers et recherche de génotypes résistants à la rouille

, 1986
La multiplication végétative in vitro du caféier, notamment le microbouturage, est envisagée pour l'étude d'une maladie foliaire, la rouille orangée, due à Hemileia vastatrix et pour la sélection de caféiers résistants.

Perennial Legumes Pueraria phaseoloides and Leucaena leucocephala Exhibit High Potential for Fertility Restoration of Degraded Mined Soils in Ghana

Journal of Plant Nutrition and Soil Science, EarlyView.
Revegetating the subsoil layer of abandoned gold mined sites with the perennial legumes Leucaena Leucocephala, Pueraria phaseoloides and Gliricidia sepium without any soil amendments increases the content of soil organic carbon and important macro‐nutrients, which are crucial for restoring soil health and productivity. These improvements in soil health

Sporophyte regeneration of Platycerium bifurcatum (Cav.) C.Chr. from in vitro germinated spores

Biotecnología Vegetal, 2013
In Cuba one of the most popular ferns, as an ornamental plant, is elkhorn (Platicerium bifurcatum) but its vegetative propagation is very slow so it is insufficient supply of this plant on the market.

Biomass Carbon in Harvest Residues of Winter Oilseed Rape Across Fertilizer N Rates: Implications for Carbon Input Estimations in Soil Carbon Models

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Reliable estimation of carbon (C) inputs from above‐ and belowground residues at different yield levels is crucial, as these inputs drive soil organic carbon (SOC) models for C accounting. Aims: This study quantifies C inputs from different components of winter oilseed rape (WOSR) and compares them with estimates from various ...

Soil Loosening of Compacted Urban Tree Sites Using a Pneumatic Lance Injector: Quantifying Treatment Success Through Tree Morphology and Soil Structure Parameters via Terrestrial Laser Scanning

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Urban trees provide essential ecosystem services, but their growth and longevity are often limited by soil compaction. Although pneumatic lance injection (PLI) is increasingly promoted as a minimally invasive and efficient soil loosening technique, but robust scientific evidence for its long‐term effectiveness remains limited.

Interaction Between Nitrogen Forms, Phosphorus Forms, and Mineral Phases Drives Phosphorus Limitation and Uptake by Ryegrass in a Model System

Journal of Plant Nutrition and Soil Science, EarlyView.
Nitrogen addition shifts plant nutrition from nitrogen to phosphorus (P) limitation. Nitrate‐based nitrogen enhances P acquisition more effectively than ammonium through increased phosphatase activity, independently of pH changes. Organic P forms induce stronger P limitation than inorganic P.

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.
