| Abstract:
Various aspects of genetic specificity of mineral nutrition have been studied in different plant genotypes. In the case of the pepper, however, such studies have been scant, despite a necessity to determine nutrient requirements of new pepper cultivars. This study dealt with the chemical heterogeneity of eight pepper cultivars which have been analyzed for the contents of nitrogen, phosphorus, potassium, calcium, sodium and ash in leaves and edible and inedible fruit parts. Contents of elements were found to depend on cultivar, plant part and element analyzed. The average content of total ash was highest in leaves, then in inedible fruit part (10.82%) and edible fruit part (8.61%). While the nitrogen content varied among the cultivars and plant parts, the contents of phosphorus and sodium did not vary much among the cultivars. The highest absolute value was found for the potassium content, which accumulated mostly in the inedible fruit part. The concentration of calcium was 3 to 4 times higher in leaves than in the other plant parts. | |
