Abstract
Bu çalışma, ıspanakta farklı elektrik akımı (DC) uygulamalarının bitki gelişimi üzerine etkilerini ortaya koyabilmek amacıyla gerçekleştirilmiştir. Saksı denemesi olarak yürütülen araştırmada farklı direkt elektrik akımı (DC) uygulamaları (0, 2, 4 ve 8 volt) ve bitkisel materyal olarak da Matador, Acosta, Revere F1 ve Rembrandt F1 ıspanak (Spinacia oleracea L.) çeşitleri kullanılmıştır. Deneme sonunda, Çıkış hızı ve yüzdesi, çıkış indeksi, bitki boyu, kök boyu, gövde çapı, yaprak sayısı, yaprak alanı, yaprak taze ve kuru ağırlığı, kök taze ve kuru ağırlığı, klorofil miktarı (SPAD değeri), lipit peroksidasyonu ürünü malondialdehit (MDA) ve enzim aktiviteleri (SOD, CAT ve APX), belirlenip; yaprakta makro-mikro besin elementi [fosfor (P), potasyum (K), magnezyum (Mg), kalsiyum (Ca), sodyum (Na), demir (Fe), mangan (Mn), bakır (Cu) ve çinko (Zn)] analizleri yapılmıştır. Yapılan DC elektrik uygulamalarından 2 ve 4 volt uygulamalarının genel olarak ıspanakta besin element içeriğini artırdığı; çeşit-elektrik interaksiyonunda ise 2 volt uygulamasının ve Rembrandt F1 ve Matador çeşitlerinin ön plana çıktığı belirlenmiştir. APX ve SOD enzim aktivitelerinde 8 volt elektrik uygulamasının ve Rembrandt F1çeşidinin, CAT enzim aktivitesi ve MDA da ise 2 volt elektrik uygulamasının ön plana çıktığı tespit edilmiştir. Sonuç olarak, genelde bazı elektrik uygulamalarının bazı ıspanak çeşitlerinde bazı bitki büyüme parametrelerine olumlu etkileri olduğu tespit edilmiştir.
The study was carried out in order to reveal the effects of different electric current (DC) applications on plant growth in spinach. In the research carried out as a pot experiment, different direct electric current (DC) applications (0, 2, 4 and 8 volts) and Matador, Acosta, Revere F1 and Rembrandt F1 spinach (Spinacia oleracea L.) varieties were used as plant material. At the end of the experiment, germination rate and percentage, plant height, root length, stem diameter, number of leaves, leaf area, leaf fresh and dry weight, root fresh and dry weight, chlorophyll amount (SPAD value), lipid peroxidation product malondialdehyde (MDA) and enzyme activities (SOD, CAT and APX), were determined; and macro-micro nutrient elements in the leaf [phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), sodium (Na), iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn) were analyzed. Of the DC electrical applications, it was determined that 2 and 4 volt applications generally increased the nutrient content of spinach; and in the variety-electricity interaction, 2 volt application and Rembrandt F1 and Matador varieties came to the fore. It was determined that 8 volt electricity application was prominent in APX and SOD enzyme activities in Rembrandt F1 variety, while 2 volt electrical application was prominent for CAT enzyme activity and in MDA enzyme activities. As a result, it has been concluded that electrical applications have positive effects on plant growth and can be used as an alternative for plant growth. As a result, it was determined that some electrical applications had usually positive effects on some plant growth parameters in some spinach cultivars.
