Abstract:
The 'Carolea', an important and widely grown Southern Italian cultivar, is self-incompatible and also presents notable levels of morphological sterility due to either insufficient, or total lack of development of the ovary.
This research examines the ability of four of the most compatible pollinizers 'Leccino', 'Nocellara Messinese', 'Coratina' and 'Tondina' to fertilize the 'Carolea' individually, and verifies the "quality" of the fertilization by observing the development of the fruit from fruit set to harvest, and comparing it with open-pollination.
Testing was carried out in an olive grove of 15 year old trees on the Sibari plain.
The trees were artificially impollinated and the entity of fruit set was observed a month after impollination, and then again in August and October.
Results showed the 'Leccino' and the 'Tondina' to be the most efficient pollinizers, while fruit set levels were better in June than at harvesting, although the differences were not statistically significant.
