Abstract

Polyphenol oxidase (PPO) activity was investigated during rooting in cuttings from three different grape cultivars (Vitis vinifera I. cvs. Muscat, Cardinal and Perlelte), and the enzyme activity and rooting ability were compared. Rooting was observed on the Muscat and Perlelte cuttings, but not on the Cardinal cuttings. PPO activity started to increase in the early stage of the experiment, and decreased after root emergence in the Muscat and Perlelte cuttings. However, enzyme activity started to increase in the early stages and continued throughout the experiment in the Cardinal cuttings. No apparent correlation was found between PPO activity and rooting ability in the cutting.

Özet

Farklı asma (Vitis vinifera 1. cvs. Muscat, Cardinal ve Perlelte) çeliklerinde koklenme sırasındaki polifenol oksidaz (PPO) aktivitesi incelenmiş ve enzim aktivitesi ile koklenme yeteneği arasındaki ilişki karşılaştırılmıştır. Bu çalışmada, Muscat ve Perlelte çeliklerinde koklenme oluşurken, Cardinal çeliklerinde oluşmadı. Muscat ve Perlelte çeliklerinin PPO aktivitesinde başlangıçtan itibaren artış görülmüş ve köklenmeyle birlikte azalma görülmüştür. Cardinal çeliklerinde ise PPO aktivitesi sürekli artmaya devam etmiştir. Sonuç olarak, çeliklerin PPO aktivitesi ile koklenme yeteneği arasında belirgin bir ilişki bulunamamıştır.
