Determination of the Effects of Ultraviolet-C and Ultrasound Applications on Seedling Growth in Tomato and Cucumber

Abstract

Nowadays, intensive researches are carried out on environment friendly alternative physical methods to promote plant growth. This study was conducted to determine the effects of ultraviolet-C and ultrasound applications, which are among physical methods, on seedling growth in tomato and cucumber, which are the most cultivated summer vegetables in the world and in our country. In the study where Falcon and H-2274 tomato varieties and Prima and Beith Alpha cucumber varieties were used as herbal material, 1) Control, 2) Ultraviolet-C (UV-C), 3) Ultrasound (US) and 4) UV-C+US applications were evaluated. In the study, seedling height, stem diameter, root length, seedling fresh and dry weight, number of leaves and chlorophyll content were determined. As a result of the research, it was determined that UV-C, US and UV-C+US applications had positive effects on the seedling growth parameters compared to the control. It was detected that UV-C+US application was more effective on seedling growth in all 4 varieties discussed in the research. When compared to the control application, UV-C+US application increased seedling height, seedling fresh weight and seedling dry weight by 16.99-45.11%, 24.82-39.88% and 37.93-52.63%, respectively, depending on the varieties. As a result, it was determined that UV-C, US and UV-C+US applications can be used as an alternative application method to increase seedling growth in tomato and cucumber.

Ultraviyole-C ve Ultrason Uygulamalarının Domates ve Hıyarda Fide Gelişimi Üzerine Etkilerinin Belirlenmesi

Öz

Günümüzde bitki büyümesini teşvik etmek amacıyla çevre dostu alternatif fiziksel yöntemlere yönelik yoğun araştırmalar yapılmaktadır. Bu çalışma, fiziksel yöntemler arasında yer alan ultraviyole-C ve ultrason uygulamalarının dünyada ve ülkemizde en fazla yetiştiriciliği yapılan yazlık sebze türlerinden domates ve hıyarda fide gelişimi üzerine etkilerini belirlemek amacıyla yapılmıştır. Bitkisel materyal olarak Falcon ve H-2274 domates çeşitleri ile Prima ve Beith Alpha hıyar çeşitlerinin kullanıldığı çalışmada 1) Kontrol, 2) Ultraviyole-C (UV-C), 3) Ultrason (US) ve 4) UV-C+US uygulamaları ele alınmıştır. Çalışmada fide boyu, gövde çapı, kök uzunluğu, fide yaş ve kuru ağırlığı, yaprak sayısı ve klorofil miktarı belirlenmiştir. Araştırma sonucunda UV-C, US ve UV-C+US uygulamalarının kontrole göre fide büyüme parametreleri üzerine olumlu etkilerinin olduğu belirlenmiştir. UV-C+US uygulamasının araştırmada ele alınan 4 çeşitte de fide gelişimi üzerine daha etkili olduğu ve kontrol uygulaması ile karşılaştırıldığında, çeşitlere bağlı olarak fide boyu, fide yaş ağırlığı ve fide kuru ağırlığını sırasıyla %16.99-45.11, %24.82-39.88 ve %37.93-52.63 oranında artırdığı belirlenmiştir. Sonuç olarak, UV-C ve US uygulamaları ile her ikisinin kombinasyonunun domates ve hıyarda fide gelişimini artırmada alternatif bir uygulama yöntemi olarak kullanılabileceği tespit edilmiştir.
