Abstract

In this research which is a basic study, the effects of low frequency electromagnetic field, 50 Hz, 0.15 mT applied with the durations of 5, 10, 15, 20 and 25 minutes to the canes of Cardinal grape variety on the vegetative growth of the cuttings were investigated. The canes applied with the electromagnetic field were cut and prepared as 5-6 cm in length having one bud before planting. The study conducted in a two-year trial, 2003 and 2005, was arranged in a randomized plot experimental design with four replications and each replication consisted of 15 cuttings. In the research, the effects of low frequency electromagnetic field onto the vegetative growth of the cuttings of Cardinal grape variety on the vigour, shooting percentage, rooting percentage, root development level, root weight, root number, shoot height, shoot weight, node number, average internode length, root weight/shoot weight and shoot+root weight parameters were investigated. In conclusion, two-year results suggested that the electromagnetic field with 0.15 mT applied to the cuttings of Cardinal grape variety found out to be significant at the level of 5% on the parameters of vigour, rooting percentage, root development level, root weight, shoot height, node number, average internode length and shoot+root weight.

ELEKTROMANYETİK ALANIN CARDİNAL ÜZÜM ÇEŞİDİ KALEMLERİNİN VEJETATİF GELİŞİMİ ÜZERİNDEKİ ETKİLERİ

Abstract

Temel bir araştırma niteliğindeki bu çalışmada, Cardinal üzüm çeşidinin yıllık dallarına 5, 10, 15, 20 ve 25 dakikalık sürelerde uygulanan 50 Hz 0.15 mT’lık düşük frekanslı elektromanyetik alanın, kalemlerin vejetatif gelişimi üzerindeki etkileri incelenmiştir. Elektromanyetik alan uygulamasına tabi tutulan yıllık dallar dikimden önce 5-6 cm uzunluğunda tek gözlü kalemler şeklinde kesilip hazırlanmıştır. 2003 ve 2005 yıllarında iki yıl süre ile yürütülen araştırma tesadüf blokları deneme desenine göre 4 tekerrürlü olarak kurulmuş ve her tekerrürde 15 adet kalem kullanılmıştır. Araştırmada, düşük frekanslı elektromanyetik alanın Cardinal üzüm çeşidi kalemlerinin gelişme gücü, sürme yüzdesi, köklenme yüzdesi, kök gelişim düzeyi, kök ağırlığı, kök sayısı, sürgün uzunluğu, sürgün ağırlığı, boğum sayısı, ortalama boğum uzunluğu, kök ağırlığı/sürgün ağırlığı ve sürgün+kök ağırlığı parametreleri üzerine etkileri incelenmiştir. Sonuç olarak, iki yıllık ortalamalar göz önünde tutulduğunda Cardinal üzüm çeşidinin yıllık dallarına uygulanan 0.15 mT’lık elektromanyetik alanın gelişme gücü, köklenme yüzdesi, kök gelişim düzeyi, kök ağırlığı, sürgün uzunluğu, boğum sayısı, ortalama boğum uzunluğu ve sürgün+kök ağırlığı parametreleri üzerinde % 5 düzeyinde önemli olduğu saptanmıştır
