Drought is one of the biggest problems nowadays and it will be mandatory to cultivate crops with limited irrigation in the upcoming days. A number of treatments are used to reduce the devastating effects of drought. Silicon and melatonin are popular treatments and, their efficacy was tested in lettuce under drought conditions for the purpose of this study. Thus, two doses of silicon (4 mM/ 8 mM), one dose of melatonin (150 µM), and their co-treatments were conducted in lettuce under two (full irrigation/drought) irrigation regimes. The physiological, photosynthetic, and basic growth parameters were measured in lettuce. Based on these data, 8 mM silicon treatment significantly mitigate the severity of drought stress. It was found that the 8mM silicon treatment had the similar leaf dry weights as the non-drought-treated and leaf fresh weight was also found to be slightly affected by drought. 8 mM silicon treatment also significantly improved the values of chlorophyll a, chlorophyll b, total chlorophyll, protein, and chlorophyll fluorescence in lettuce under drought stress. Additionally, melatonin treatments (150 µM) resulted in significant increases in the examined parameters of the non-drought-treated lettuce groups. Consequently, it was concluded that silicon fertilization alleviated the adverse effects of drought or limited irrigation conditions, whereas, under full irrigation conditions, silicon and melatonin treatments contributed significantly to lettuce cultivation.

Marulda Kuraklık Stresine Karşı Toleransının Silisyum ve Melatonin Uygulamalarıyla Artırılması

Kuraklık günümüzün en büyük problemleri arasında yer almaktadır ve önümüzdeki günlerde kısıtlı sulama ile üretim yapma zorunluluğu doğacaktır. Kuraklığın yıkıcı etkilerini azaltmak için günümüzde çeşitli uygulamalar yapılmaktadır. Silisyum ve melatonin popüler uygulamalardan olup çalışmamızın amacı kapsamında marulda kurak şartlarda etkinlikleri test edilmiştir. Bu nedenle, iki doz silisyum (4 mM/8 mM), bir doz melatonin (150 µM) ve bunların combinasyonlar marulda iki (tam sulama/kuraklık) sulama rejimi altında test edilmiştir. Marulda fizyolojik, fotosentetik ve temel büyüme parametreleri ölçülmüş ve bu verilere dayanarak, 8 mM silikon uygulamasının kuraklık stresinin şiddetini önemli ölçüde azalttığı belirlenmiştir. Kurak şartlarda 8 mM silisyum uygulamasının, kuraklık uygulanmayan grup ile benzer yaprak kuru ağırlığına sahip olduğu ve yaprak taze ağırlığının da kuraklıktan daha az etkilendiği tespit edilmiştir. 8 mM silikon uygulaması ayrıca kuraklık stresi altındaki marulda klorofil a, klorofil b, toplam klorofil, protein ve klorofil floresansı değerlerini önemli ölçüde iyileştirdi. Ayrıca, melatonin uygulamaları (150 µM) kuraklık uygulanmayan marul gruplarında incelenen parametrelerde önemli artışlara neden olmuştur. Sonuç olarak, silisyum gübrelemesinin kuraklık veya kısıtlı sulama koşullarının olumsuz etkilerini hafiflettiği, tam sulama koşulları altında ise silisyum ve melatonin uygulamalarının marul yetiştiriciliğine önemli katkı sağladığı belirlenmiştir.
