Abstract

[automatically translated] The present research has used increasing doses of molybdenum in order to evaluate its effect on some of IV range products. Given that the accumulation of molybdenum and nitrate in the leaves was for all theses in evidence always well below the limits considered harmful to human health, the results were not always those expected and the three test species were distinguished by a different behavior in terms of Mo accumulation, production and quality of the obtained product. In particular, for the optimal dose lettuce which allows good production and quality outcomes (in terms of colorimetric parameters and modest content in nitrate) it seems to be that traditionally suggested of 0.5 mol / l, although with higher doses significantly increases the content of vitamin C. In the case endive smooth, the results were more evident: the optimal dose to achieve maximum production corresponds to 1.5 mol / l of molybdenum while increasing doses lead to considerable improvements in quality in terms of higher content of ascorbic acid, soluble solids and vitamin C and lower content nitrate. The curly sull'indivia of molybdenum effects were less pronounced but significant for some quality parameters: increasing dose fact increases the titratable acidity and vitamin C, improves the soluble solids and tends to reduce the nitrate content. 5 mmol / l of molybdenum while increasing doses result in considerable improvements in quality in terms of higher content of ascorbic acid, soluble solids and vitamin C and lower content in nitrate.
