Root-applied glycinebetaine controls nitrate content and edible quality of lettuce in continuous commercial hydroponic greenhouse production

Frontiers in Sustainable Food Systems, 2023
Lettuce (Lactuca sativa L.) may accumulate high amounts of nitrate NO3− in hydroponic cultivation, such as in the Nutrient Film Technique (NFT) system.

Lettuce Infectious Yellows Tolerance in Lettuce

Journal of the American Society for Horticultural Science, 1986
Abstract Lettuce ( Lactuca sativa L.) cultivars and breeding lines differed in tolerance to lettuce infectious yellows virus. Correlations of symptom severity in field tests with fresh weight of control plants in a greenhouse test indicate a relationship between symptom ...

Distribution of genetic diversity in wild European populations of prickly lettuce (Lactuca serriola): implications for plant genetic resources management

, 2010
Genetic variation in Lactuca serriola, the closest wild relative of cultivated lettuce, was studied across Europe from the Czech Republic to the United Kingdom, using three molecular marker systems, simple sequence repeat (SSR, microsatellites), AFLP and

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

Advanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Machine Learning‐Driven Prediction of Microplastic Aging Processes and Environmental Risk Assessment Across Multi‐Media Systems

Advanced Science, EarlyView.
This perspective proposes a cohesive machine learning strategy to decode microplastic aging. It advocates for Federated Learning to dismantle global data silos and introduces the TRACE framework (TRansport, Aging, Corona, Ecotoxicity). By integrating physics‐informed modeling with causal discovery, this approach bridges the laboratory‐field gap to ...

Excipient Emulsion–Based Delivery Systems for Enhancing Carotenoid Bioavailability: Advances in Formulation and Gastrointestinal Fate

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Excipient emulsion systems improve carotenoid solubilization, protect against degradation, and enhance gastrointestinal absorption through optimized formulation and digestion behavior. ABSTRACT Carotenoids are bioactive compounds that contribute to human health through antioxidant, provitamin A, and disease‐preventive effects.

Quality of lettuce Lactuca sativa (var. Tropicana M1) grown with two low-salinity shrimp effluents

Food Chemistry: X, 2019
In a previous study, we investigated the use of shrimp effluents from well water (WW) and diluted seawater (DSW) (both with 2.7 dS m−1 electrical conductivity (EC)), and a hydroponic solution (HS) as the control treatment in greenhouse lettuce production.
