Kavunda Anaç (C. maxima × C. moschata) Kullanımının Yaprak Tüylülüğü Üzerine Etkisi

Yaprak tüy sayısı ve tüy yoğunluğu farklı stres faktörlerinin etkilerini azaltmada etkili olabilmektedir. Çalışmanın amacı, kavun bitkisinde yaprak tüy yoğunluğu üzerine anaç kullanımının etkisini belirlemektir. Bu amaçla iki adet ticari kabak anacı (Kardoso ve Nun 9075) üzerine aşılanan Galia tipi (Çıtırex F1) kavun ve aşısız Çıtırex kavun çeşidi kontrol olarak kullanılmıştır. Çalışma sonuçlarına göre yaprak tüy sayısı ve tüy yoğunluğu en yüksek aşılı bitkilerde elde edilirken, en düşük ise aşısız bitkilerinden elde edilmiştir. Yapraklarda külleme zararı ve Tetranychus urticae (iki noktalı kırmızı örümcek) zararının aşılı bitkilerde azaldığı tespit edilmiştir. Kavunda aşılama ile yaprak tüylülüğünün artırılabileceği ve buna bağlı olarak bazı yaprak zararlanmalarının azaltılabileceği değerlendirilmektedir. Herbivorlar ve patojenlerin bitki performansı üzerindeki etkisini anlamaya çalışan araştırmalar, çevrenin ve anaç kullanımının yaprak tüylülüğü üzerindeki etkisini de dikkate almalıdır.

The Effect of Rootstock (C. maxima × C. moschata) Use on Leaf Hairiness in Melon

The number of leaf hairs and hair density can be effective in reducing the effects of different stress factors. The aim of the study is to determine the effect of rootstock usage on leaf hair density in melon plant. For this purpose, Galia type (Çıtırex F1) melon grafted on two commercial pumpkin rootstocks (Kardoso and Nun 9075) and ungrafted Çıtırex melon variety was used as control. According to the results of the study, the highest leaf hair number and hair density were obtained from grafted plants, while the lowest was obtained from non-grafted plants. It was determined that powdery mildew damage on leaves and Tetranychus urticae (Two spotted spider mites) damage were reduced in grafted plants. It is evaluated that the leaf hairiness can be increased by grafting in melon and accordingly some leaf damage can be reduced. Studies seeking to understand the impact of herbivores and pathogens on plant performance should also consider the impact of the environment and rootstock use on leaf hairiness.
