Capsicum annuum L., SPAD index, BRIX%, total capsaicin


The marketability of the sweet peppers is determined by their quality in Class I, which must also meet the highest standards in terms of the color, shape of the variety and the characteristics of the various flavors. However, the determinants of quality may vary from one pepper type to another. During of our research, we examined the utilization of nitrogen, magnesium and potassium in different types of domestic peppers in the context of the relative chlorophyll content of the foliage and the amount of sugar and total capsaicin in the fruits. We determined that the nutrient solution prepared by Duna-r Ltd. is suitable for achieving the highest sugar and capsaicin content, but their levels can differ significantly. The uptake and utilization of nitrogen, magnesium and potassium of nutrient solution can be checked with the SPAD (Soil Plant Analysis Development) index data of the foliage. We found that there are periods in the phenophase of the pepper cultivars studied when both sugar content and capsaicin content increase significantly. Another major result is that sugar content is a basic determinant of capsaicin content in hot peppers and cherry peppers, while it is not an important factor of capsaicin content for Bogyiszló-type peppers.
