SPRING PHENOLOGICAL GROWTH STAGES OF ACTINIDIA ARGUTA PLANCH

The kiwi berry is a relative new fruit crop in Belgium.
As for other fruit crops a number of horticultural practices (such as pruning, frost protection, pollination techniques, fertilization, etc.) have to be applied and a knowledge of the crop phenology in our region can support these techniques.
The phenological stages from dormant vines to fruit setting were described for four Actinidia argute cultivars ‘Geneva’, ‘Jumbo’, ‘Ken’s Red’ and ‘Weiki’ (both pistillate and staminate plants). For this description we utilized the nomenclature that has been used for Actinidia deliciosa ‘Hayward’ and according to the BBCH General Scale.
Data were recorded during two consecutive growing seasons, one commercial orchard in 2010 and two commercial orchards in 2011. Microclimate has an effect on phenological development: south-oriented laterals develop slightly earlier.
Not all buds on the lateral branches are generative: a preference gradient for vegetative buds (on average first 8 buds) and flower buds (later formed buds) was observed.
