RED CHIEF ELMA ÇEŞİDİNDE AMİNOETHOXYVİNYLGLYCİNE’NİN (AVG) VE NAFTALEN ASETİK ASİT’İN (NAA) HASAT ÖNÜ DÖKÜM VE MEYVE KALİTESİ ÜZERİNE ETKİSİ

Bu çalışma Tokat ekolojik koşullarında Red Chief elma çeşidinin (Malus domestica Borkh.) hasat önü dökümünü azaltmak ve meyve kalitesini artırmak amacıyla yürütülmüştür. Bu amaçla 150, 300, 600 mg L–1 aminoethoxyvinylglycine ve 20 mg Lnaftalen asetik asit, tahmini hasat tarihinden 4 hafta önce deneme ağaçlarına püskürtülmüştür. Çalışmada kümülatif döküm yüzdesi (%), kopma direnci (N), nişasta indeksi, meyve rengi (L*, C*, h°), meyve ağırlığı (g), suda çözünebilir kurumadde miktarı [SÇKM, (%)], pH, titre edilebilir asitlik ve meyve eti sertliği (N) ölçümleri yapılmıştır. Tahmini hasat tarihinde AVG’nin 300 ve 600 mg L–1 dozları dökümü azaltmada kontrol ve NAA uygulamasından önemli düzeyde (P
