ABSTRACT: Kiwifruit culture mainly comprises Actinida deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson varieties, selected by the quality of their fruit. The most widely cultivated variety is 'Hayward'; being its flowers formed in the shoots of 1-year old canes. In the shoots developing from each axillary bud there are eight potentially reproductive meristems (nodes 5 to 12). From node 13 onwards, leaves are developed, whereas the buds are progressively less developed (Brundell, 1975). Pistillate flowers appear in dichasia formed by a terminal flower and two lateral flowers; in the case of “Hayward”, lateral flowers generally abort (Hopping, 1990), which leads to the development of the fruit only in the terminal flower. However, in some years during cold winters the lateral flowers complete their development and inflorescences with two or three flowers are produced. In Spain, the first orchards of A. deliciosa were established in Galicia in the 70s from plants imported of the ‘Hayward’ cultivar. At present, Galicia is the main producing region in Spain, with 820 ha of cultivated land, producing 13,260 t of fruit, accounting for 76.4% of the Spanish production. All pistillate flowers of the Galician plantations are regarded as 'Hayward'. However, it is frequent to observe in the kiwifruit orchards vines showing phenotypic characteristics that are different from ‘Hayward’, since they present shorter fruiting shoots that form dense bunches. The aim of the present work was to compare the agromorphological and productive features of typical and non-typical 'Hayward' vines in Galician orchards. |
