| Abstract:
Research has been carried out on the recovery of reproductive behavior and fruit characteristics, after regeneration pruning in ten olive cultivars: "Adramitini", "Agouromanakolia", "Lianolia Kerkyras", "Koroneiki", "Koutsourelia", "Mastoidis", "Megaritiki", "Valanolia", "Kalamon", "Amphissis" (12 trees/cv), with the aim of improving quantity and quality of the crop. The crop data used for this research were recorded for seven to ten years under dried and irrigated conditions at four replications on the experimental orchard of Subtropical Plants and Olive Trees Institute in Chania. Flowering amount, fruit set trend, fertility, fruit removal force, fruit technological properties like weight and size, flesh percentage, yield and alternative bearing were measured. All studied cultivars showed similar fruit development and shoot growth patterns with differences in the crop load and oil content. The percentage of fertile clusters differed among the cultivars and the fruits developed according to the same model but at different rates. In all cultivars shoots grew at a more intense rate after pruning and an improvement of olive fruit quality, were found during the ten years after pruning, (better flesh to pit ratio, higher percentage of olive oil, earlier maturation, higher productivity). | |
