Sweet Cayenne pepper is a nutrient-dense, sweet-tasting greenhouse vegetable that often faces water stress in dry areas, and optimizing growth with minimum consumption crucial. In this study, we investigated the impacts of amino acids (AAs) foliar application on reducing losses sweet cv. “Lombard” under conditions. The bushes were irrigated 3-day 6-day intervals simultaneously sprayed an AA fer...

Grafting favors the presence of bioactive compounds in the bell pepper, but many species and varieties have not yet been analyzed in this sense, including commonly grafted varieties. The aim of the present study is to characterize the content in β-carotenes, vitamin C, lycopene, total phenols, and the antioxidant activity of bell pepper (Capsicum annum L.) using the cultivar/rootstock combinati...

BACKGROUND AND AIMS Pepper (Capsicum annuum, Solanaceae) fruits are consumed worldwide and are of great economic importance. In most species ripening is characterized by important visual and metabolic changes, the latter including emission of volatile organic compounds associated with respiration, destruction of chlorophylls, synthesis of new pigments (red/yellow carotenoids plus xanthophylls a...

Characterisation of internal atmosphere composition offers the potential to explain variability in responses of horticultural crops to modified atmosphere treatments and to quantify permeance of fruit skins to the respiratory gases. In this paper, the theoretical basis by which fruit skin permeance can be calculated from other gas exchange variables is presented. Surface chambers close to equil...

*Part of the dissertation necessary for the M.Sc. degree in Plant Pathology of the first author, Universidade de Brasília (2002). CAPES fellowship Determination of virus diversity in the field is vital to support a sustainable breeding program for virus resistance of horticultural crops. The present study aimed to characterize four field potyvirus isolates found naturally infecting sweet pepper...

BACKGROUND Dihydrocapsiate (DCT) is a natural safe food ingredient which is structurally related to capsaicin from chili pepper and is found in the non-pungent pepper strain, CH-19 Sweet. It has been shown to elicit the thermogenic effects of capsaicin but without its gastrointestinal side effects. METHODS The present study was designed to examine the effects of DCT on both adaptive thermogen...
