PERFORMANCE OF KIWIFRUIT PLANT MATERIAL PROPAGATED BY DIFFERENT METHODS

Trials were performed in order to study the effect of different propagation methods (rooting of soft-wood cuttings, grafting on ‘Bruno’ seedling rootstocks and micropropagation) on vigor, yield and fruit size for the period 1989–1992. Both for "in vitro" propagated and soft-wood cutting plants, wood was collected in August 1985 from the same vine cv. ‘Hayward’. Graftings were made, with this vine, in may 1986 on one-year-old ‘Bruno’ seedlings.
The experimental orchard was established in march 1987 in Asturias, Northern Spain.
Vines were trained onto ‘T-Bar’ system with 5 m in and between the rows.

Although commercial production the first harvest was significantly higher in grafted plants, the following years plants obtained from cuttings showed greater vigor and higher cumulative and commercial yield.
Micropropagated vines shown a later coming into production and significant lower values for all parameters in study.
