Secondary metabolites in different species of Brassica vegetables grown in greenhouse
In Galicia (northwestern Spain), different Brassica species are used as leaf vegetable products for human and also for animal consumption. Kales (Brassica oleracea acephala group), cabbages (B. oleracea capitata group), leaf rape (B. napus pabularia group), and turnip tops and turnip greens (B. rapa...

| Sumario: | In Galicia (northwestern Spain), different Brassica species are used as leaf vegetable products for human and also for animal consumption. Kales (Brassica oleracea acephala group), cabbages (B. oleracea capitata group), leaf rape (B. napus pabularia group), and turnip tops and turnip greens (B. rapa rapa group) are the most important Brassica crops in this region. At the Misión Biológica de Galicia (CSIC, Spain), a collection of local varieties of these species is kept in a Germplasm Bank. The glucosinolate and phenolic profile, metabolites related with human health, has been previously studied in this collection (Padilla et al., 2007b; Velasco et al., 2007;2008; Cartea et al., 2008a; 2008b; Francisco et al., 2009) under field conditions. Nevertheless, due to the yield losses caused by several pests and the adverse weather conditions throughout the growing season, these crops are increasingly being cultivated under cover or greenhouse conditions. In these conditions, the content in secondary metabolites may be quite different and it has not been studied yet. For this reason, the objective of this work was to quantify the glucosinolate and phenolic content of four different crops: kale, cabbage, leaf rape and turnip greens grown under greenhouse conditions in two different times and to compare them with the same varieties studied in the field in different experiments. |
