Abstract

This study was carried out to determine the effects on biochemical changes with growth parameters of seaweed (Ascophyllum nodosum) extract applications (control, 2, 4 and 6 cc l-1) and drought stress at the different osmotic pressure (control,-0.5 MPa, -1.0 MPa and -1.5 MPa) generated by PEG 6 000 in echinacea. In this study, root length, shoot length, root and shoot fresh weight, root and shoot dry weight, total antioxidant and total phenolic content of echinacea plant were investigated. As a result of the research; it was decreased the root fresh and dry weight, shoot fresh and dry weight, root and shoot length of drought stress. It was determined caused to increase total antioxidant substance amount. Drought stress did not have a significant effect on total phenolic content. It has been reduced with seaweed applications the negative effects on the plant of drought stress. It has been positive and increasing the effects on examined parameters such as root length, shoot length, root and shoot fresh weight, root and shoot dry weight of seaweed applications while seaweed application did not affect at the significant level as statistically total antioxidant and the phenolic substance amount.

Özet

Bu çalışma, Echinacea purpurea L.’ da PEG 6 000 ile oluşturulan farklı ozmotik basınçta (kontrol, -0.5 MPa, -1.0 MPa ve -1.5 MPa) kuraklık stresi ile deniz yosunu (Ascophyllum nodosum) (kontrol, 2, 4 ve 6 cc/l) uygulamalarının büyüme parametreleri ile biyokimyasal değişiklikler üzerine etkilerini belirlemek amacıyla yürütülmüştür. Çalışmada ekinezya bitkisinin kök uzunluğu, gövde uzunluğu, kök yaş ağırlığı, gövde yaş ağırlığı, kök kuru ağırlığı, gövde kuru ağırlığı, toplam antioksidan ve toplam fenolik miktarları incelenmiştir. Araştırma sonucunda; kuraklık stresinin bitkinin kök yaş ve kuru ağırlığı, gövde yaş ve kuru ağırlığı, kök ve gövde uzunluğunu azalttığı, toplam antioksidan madde miktarında ise artışlara neden olduğu belirlenmiştir. Kuraklık stresinin toplam fenolik madde miktarı üzerine ise önemli bir etkide bulunmadığı tespit edilmiştir. Deniz yosunu uygulamaları ile kuraklık stresinin bitki üzerindeki olumsuz etkileri azaltılmıştır. Deniz yosunu uygulamalarının kök uzunluğu, gövde uzunluğu, kök yaş ağırlığı, gövde yaş ağırlığı, kök ve gövde kuru ağırlığı üzerindeki etkisi olumlu ve arttırıcı yönde olduğu tespit edilirken, toplam antioksidan ve fenolik madde miktarını istatistiki olarak önemli seviyede etkilemediği belirlenmiştir.
