Table 3. Mean values and range of composition traits of S. melongena MEL5, MEL1, and MEL3 in LN and NN cultivation conditions and ABsof S. insanum (INS; n = 25), S. dasyphyllum (DAS; n = 59), and S. elaeagnifolium (ELE; n = 59) in low nitrogen (LN) cultivation conditions. The full name of each trait in the first column can be found in Table 5. For each trait, means with different letters are significant according to the Student–Newman–Keuls multiple range test (P < 0.05).
