Abstract

Objective: This study was conducted to analyze the physiobiochemical responses of two sorghum-sudangrass (Sorghum bicolor×Sorghum Sudanese Stapf.) hybrid (“Aneto” and “Sugar Graze”) seedlings exposed to salt stress. Materials and methods: Sorghum-sudangrass hybrid seeds sown in MS medium containing 50 and 100 mM NaCl. The activity of antioxidant enzymes (SOD, CAT, GR, APX), chlorophyll (a, b, and total), malondialdehyde (MDA), and proline levels measured in 14 days old seedlings. Results: As a result of the study, the activity of antioxidant enzymes (CAT, SOD, APX, and GR), malondialdehyde (MDA), proline and chlorophyll contents of seedlings of cv. “Aneto” increased. On the other hand, SOD activity, proline, and chlorophyll content increased while CAT, APX, GR activity, and malondialdehyde (MDA) content decreased in seedlings of cv. “Sugar graze”. Conclusion: Overall, the results showed that the cv. “Aneto” was less affected by the adverse effects of salt stress than the cv. “Sugar graze”. This study is essential for revealing biochemical responses of 14days old Sorghum-Sudanese hybrid seedlings against salt stress. These study findings can use in breeding programs for sorghum plants.

Özet

Amaç: Bu çalışma, tuz stresine maruz burakılan iki sorgum-sudangrass (Sorghum bicolor× Sorghum sudanense Stapf.) hibrit (“Aneto” ve “Sugar Graze”) fidelerinin fizyo-biyokimyasal tepkilerini analizi için yapılmıştır. Gereç ve Yöntem: Sorgum-sudangrass hibrid tohumları içerisinde 50 ve 100 mM NaCl içeren MS ortamlarına ekilmiştir. 14 günlük fidelerde, antioksidant enzimlerin aktivitleri (SOD, CAT, GR, APX), klorofil (a, b ve toplam), malondialdehit (MDA) ve prolin seviyeleri ölçülmüştür. Bulgular: Çalışma sonucunda, “Aneto” çeşidinin fidelerinde, antioksidant enzimlerin (CAT, SOD, APX ve GR) aktivitesi, malondialdehit (MDA), prolin ve klorofilin içerikleri artmıştır. Diğer taraftan, “Sugar graze” çeşidin fidelerinde, SOD aktivitesi, prolin ve klorofil içeriği artarken, CAT, APX, GR aktivitesi ve malondialdehit (MDA) içeriği azalmıştır. Sonuç: Genel olarak, sonuçlar tuz stresinin olumsuz etkilerinden “Sugar graze” çeşidi ile kıyaslandığında “Aneto” çeşidinin daha az etkilendiği göstermiştir. Bu çalışma, 14 günlük Sorgum-Sudanotu melez fidelerin tuz stresine karşı biyokimyasal tepkilerini ortaya çıkarması bakımından önemlidir. Sorgum bitki için ıslah programlarında bu çalışma bulguları kulanılabilir.
