FLOWERING AND FRUITING MORPHOLOGY OF HARDY KIWIFRUIT, ACTINIDIA ARGUTA

Morphology of Actinidia arguta ‘Ananasnaya’ vines was studied in 1998 and 1999 in Oregon, USA. Vines were three years old (1998) and trained on a pergola trellis.
The origination of one-year-old fruiting wood had no effect on percent fruitful shoots or the number of clusters or fruit per meter of cane.
One-year-old canes produced fruitful shoots along their entire length, but were most productive from nodes 6 to 26. In 1999, of 2085 nodes/vine left after winter pruning, bud break was 47%, 85% of the shoots continued to grow past 15cm long, and 83% of these were fruitful.
The most productive flowering zone on shoots was from nodes 6 to 12. There was no relationship between yield per vine and return bloom the following year.
Fruit set was 74%. There was a significant linear relationship between fresh fruit weight and seed number.
