RELATIONSHIPS BETWEEN BRANCH-TIERS AND FRUIT QUALITY IN CENTRAL LEADER TRAINING SYSTEM FOR APPLES

Abstract

This study was conducted to determine relationship between branch tiers and fruit quality in apple trees trained with central leader training system. The study was carried out under Eğirdir-Isparta conditions and Williams' Pride (Co-op no: 23) apple variety trees grafted onto MM 106 rootstock were used. Fruit firmness, lightness (L*) and chroma (C*) values of the fruits on the basal branch tier were higher than those of the fruits on the upper branch tiers. However, fruit diameter, weight, soluble solids content (SSC), fruit skin color hue angle values and bitter pit values of fruits were higher on the upper branch tiers than basal branch tier. Red color index value was 61.8% on the upper branch tiers while 53.2% on the basal tier. It was determined that basal tier produced almost 40% of total fruit yield, but it gave less quality fruits than the upper branch tiers.

ELMALARDA MERKEZİ LİDER TERBİYE SİSTEMİNDE DAL KATLARI VE MEYVE KALİTESİ ARASINDAKİ İLİŞKİLER

Abstract

Bu çalışma merkezi lider terbiye sistemi uygulanmış elma ağaçlarında dal katları ve meyve kalitesi arasındaki ilişkileri tespit etmek amacıyla yapılmıştır. Eğirdir-Isparta şartlarında yürütülen çalışmada, merkezi lider terbiye sistemi uygulanmış MM 106 anacına aşılı Williams' Pride (Co-op no: 23) elma çeşidine ait ağaçlar kullanılmıştır. Çalışma süresince alt katta bulunan meyvelerde sertlik, lightness (L*) ve chroma (C*) değerleri, üst katlara nazaran daha yüksek olmuştur. Meyve eni, ağırlık, suda çözünebilir kuru madde miktarı (SÇKM) ve meyve kabuk rengi değerlerinden hue açısı ile acı benek oranı alt kata nazaran, üst katlarda daha yüksek olmuştur. Üst katlarda %61.8 olan kırmızı renk indeksi, alt katta %53.2 olarak tespit edilmiştir. Meyve veriminin yaklaşık % 40’ının alındığı alt kattaki meyvelerin, üst katlardaki meyvelere göre irilik ve renk gibi önemli kalite kriterleri açısından daha düşük değerler aldığı saptanmıştır.
