The analyses were performed by DPPH and FRAP methods for antioxidant activity. In the study, the plants grown in Bulancak location had significantly higher nitrogen, protein and antioxidant activity than other growing regions. On the contrary, significantly lower nitrogen and protein were measured in plants grown in Espiye and Tirebolu. The total phenolics and total flavonoids were determined the highest in plants grown in Espiye and Tirebolu locations, the lowest values in Çamoluk and Şebinkarahisar locations. According to the antioxidant activity tests, the antioxidant activity of the plants grown in Espiye location was significantly higher than in other growing regions. The lowest antioxidant activity was measured in Şebinkarahisar and Çamoluk locations. As a result, it was revealed that region conducted the cultivation affects on the protein and bioactive compounds of the Moringa oleifera plant. Espiye, Bulancak and Tirebolu locations can be recommended for cultivation.

Thus, genetically improved stress-tolerant varieties are needed for the future. The identification of salt-tolerant genotypes is the starting point for such breeding studies. This study was conducted to determine and assess the tolerance of different watermelon genotypes under saline conditions. Twenty-two watermelon genotypes and accessions were grown in pots with 3 kg of soil in four saline stress conditions (0 mmol kg-1 as the control, 25, 50 and 100 mmol kg-1 NaCl). The detrimental effects of salt stress on the plants were evident with increasing doses of NaCl. Stress indices calculated over the plant dry weights under the 100 mmol kg-1 salinity level were used to assess the salt tolerance of the genotypes. Stress intensity was calculated as 0.76. Such a value indicated that the highest dose of salt exerted severe stress on the plants. The G04, G14 and G21 genotypes were con...

Yenice and Pinarli bean genotypes ( Phaseolus vulgaris L.) commonly grown in Camoluk region in Central Black Sea Region of Turkey were used as the plant material of this study. Significant differences were observed in ash, crude fibre, lipids, moisture, protein, salt and sucrose content of bean genotypes.

Yenice and Pinarli bean genotypes (Phaseolus vulgaris L.) commonly grown in Çamoluk region in Central Black Sea Region of Turkey were used as the plant material of this study. Significant differences were observed in ash, crude fibre, lipids, moisture, protein, salt and sucrose content of bean genotypes. While sucrose (4.56 g 100 g-1), salt (0.12 g 100 g-1) carhydrates (38.41 g 100 g-1) and crude fiber (25.57 g 100 g-1) values were higher in Pinarli , lipids (1.69 g 100 g-1) and protein 21.72 g 100 g-1) contens were higher in Yenice genotype. Similarly, vitamin levels were also significantly different. Thiamine (0.50 mg 100 g-1), niacin (3.82 mg 100 g-1), retinol (4.15 µg 100 g-1), riboflavin (0.16 mg 100 g-1), pyridoxine (0.33 µg 100 g-1) and folate (234.50 µg 100 g-1) contents of Pinarli genotype were significantly higher than Yenice. Potassium content (16145.0 mg kg-1) of Yenice genotype and phosphorus content (8349.1 mg kg-1) of Pinarli genotype were also found statistically significantly. Except for tryptophan and phenylalanine, significant differences were also observed in amino acids of bean genotypes. Amino acid content of Pinarli genotype was also higher than Yenice genotype.Both genotypes were especially rich in aspartic acid, lysine and glutamic acid.

Stress indices calculated over the plant dry weights under the 100 mmol kg-1 salinity level were used to assess the salt tolerance of the genotypes. Stress intensity was calculated as 0.76. Such a value indicated that the highest dose of salt exerted severe stress on the plants. The G04, G14 and G21 genotypes were considered to be salt tolerant, since these genotypes showed the highest values of K/Na and Ca/Na ratios in the plant tissue. The losses in dry mass at severe salt stress reached 75.48%. In principal component analyses, the genotypes had positive correlations with stress tolerance indices of MP (mean productivity), GMP (geometric mean productivity) and STI (stress tolerance index). The GMP and STI indices indicated that G04 (a member of Citrullus colocynthis), G14 and G21 could be prominent sources to develop salt tolerance. RESUMO O estresse salino é a restrição mais importante para a produção agrícola em regiões áridas e semi-áridas. Portanto, há necessidade de plantas geneticamente tolerantes ao estresse salino no futuro. Identificação de genótipos tolerantes ao sal é o ponto de partida de estudos de melhoramento. O presente estudo foi conduzido para determinar e avaliar a tolerância de diferentes genótipos de melancia sob condições salinas. Um total de 22 genótipos e acessos de melancia foram cultivados em vasos de 3 kg de solo com quatro condições de estresse salino diferentes (0 mmol kg-1 como controle, 25, 50 e 100 mmol kg-1 de NaCl). Dependendo do aumento da dose de NaCl, os efeitos prejudiciais do estresse salino nas plantas também aumentaram. Os índices de estresse calculados sobre os pesos secos das plantas com um nível de salinidade de 100 mmol kg-1 foram utilizados para avaliar a tolerância ao sal dos genótipos. A intensidade de tensão foi calculada como 0.76. Indicando que a maior dose de sal exerce um estresse salino grave nas plantas. Os genótipos G04, G14 e G21 foram considerados tolerantes, uma vez que apresentaram os maiores valores nas relações K/Na e Ca/Na. As perdas em pesos secos com estresse salino grave atingiram 75.48%. Na análise de componentes principais, os genótipos tiveram correlações positivas com os índices de tolerância ao estresse de PM (produtividade média), GMP (produtividade média geométrica) e STI (índice de tolerância ao estresse). Os índices GMP e STI indicaram G04 (um membro de C. colocynthis), G14 e G21 como materiais proeminentes para a tolerância ao sal.
