Résumé
Herbs are a rich source of active phytochemicals (flavonoids, phenols, antioxidants, ascorbic acid, carotenoids, mineral salts and terpenoids. They are an ancient source of flavouring, aromatic compounds and medicine. Herbs have always constituted an important component of the human diet, adding variation and flavour to staple foods, as well as being used for food preservation. They are mostly processed because of the perishable nature of its leaves. The quality of herbs therefore can be improved by the manipulation of light quality during production and also by sheltering them from environmental hazards such as excessive solar radiation, wind and flying pests. In this study the effect of photo-selective netting technology (ChromatiNet™) (red, pearl and yellow) with 40% shading and commercial black net with 25% shading used as a control were investigated on herbs. Three herbs (coriander, marjoram and oregano) were planted. The aim of the present study was to evaluate the responses of the three photo-selective nets (red, pearl and yellow) and the black net (control) on quality parameters and bioactive compounds in herbs (in this study, coriander, marjoram and oregano).
