INFLUENCE OF DIFFERENT OLIVE ROOTSTOCKS ON GROWTH AND PRODUCTION OF ‘GORDAL SEVILLANA’

The influence of 20 olive rootstocks on growth and production of ‘Gordal Sevillano’, also comparing the self-rooted ‘Gordal’ is studied. In the 4th year of field implanting, according to plant height and width (canopy diameter) the following growth classification can be done:

• Rootstocks inducing big growth: Acebuche, ‘Morisca de Badajoz’, ‘Azulejo’, ‘Lechín de Sevilla’, ‘Real sevillana’, ‘Cornezuelo’ and ‘Aloreña’.
• Rootstocks inducing normal growth: ‘Cañivano’, ‘Carrasqueña’, ‘Gordal’, ‘Blanqueta’, ‘Tempranilla de la Sierra’, ‘Changlot’, ‘Manzanilla de Jaén’, ‘Alameño’ and ‘Pico-limón’.
• Rootstocks inducing little growth: ‘Redondilla de Logroño’, ‘Picual’, ‘Buidiego’, ‘Hojiblanca’ and ‘Habichuelero’.

Plants with large production are: ‘Morisca de Badajoz’, ‘Cañivano’, ‘Acebuche’, ‘Manzanilla de Jaén’, ‘Carrasqueña’, ‘Gordal’ and ‘Tempranilla de la Sierra’. Ratio between plant height and width and fruit quality (ratio between the two transversal axis of the fruit and ratio between pulp and stone) are also considered.
