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.
