The tomato-potato psyllid Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) is a pest of many solanaceous plants, including tomato (Solanum lycopersicum L.) and potato (Solanum tuberosum L.). In tomato, feeding by nymphs is associated with "psyllid yellows." B. cockerelli also vectors "Candidatus Liberibacter psyllaurous," an infectious bacterium that causes "vein greening" disease.

The amounts of three flavonoids, quercetin, kaempferol, and myricetin, in tomatoes (Solanum lycopersicum L.) and tomato-based products produced in Turkey has been determined by reversed phase high-performance liquid chromatography (RPHPLC) with UV detection. The HPLC profiles of five types of tomato, one commercial composite tomato juice, and three types of tomato paste, were obtained after aci...

Biosynthesis of ent-kaurene was investigated in extracts of cell suspension cultures derived from tobacco callus (Nicotiana tabacum L.), tomato callus (Solanum lycopersicum L.), and in germinating tomato seeds. Incubation of extracts derived from the two cell cultures with either isopentenyl pyrophosphate-(14)C or with (14)C-labeled mevalonate, followed by alkaline phosphatase hydrolysis, resul...

Ethylene sensitivity of grafted and nongrafted tomato ( Solanum lycopersicum ) seedlings with three to four true leaves was examined. The concentration exogenous ethylene that produced symptoms between 1 10 µL?L –1 regardless grafting. Symptoms exposure included leaf epinasty, decreased maximal photochemical quantum yield photosystem II F v / m ), increased plant height (nongrafted only). Graft...
