Stability of fruit quality traits in diverse watermelon cultivars tested in multiple environments.

Lycopene is a naturally occurring red carotenoid compound that is found in watermelon. Lycopene has antioxidant properties. Lycopene content, sugar content and hollowheart resistance are subject to significant genotype×environment interaction (G×E), which makes breeding for these fruit quality traits difficult.

Fate of manure-borne pathogen surrogates in static composting piles of chicken litter and peanut hulls.

The fate of manure-borne pathogen surrogates (gfp-labeled Escherichia coli O157:H7 and Listeria innocua and avirulent Salmonella Typhimurium) in the field was monitored at both sub-surface (30 cm from surface) and surface sites of static composting piles (3.5-m base diameter) composed of chicken litter and peanut hulls. Despite exposure to elevated temperatures, Salmonella was detected by enrichment culture in sub-surface samples following 14 days of composting.
