Abstract Seasonal cycles of shoot development for 10
Actinidia species are described. A female and a male vine were studied
for six species. Shoots were sampled at monthly intervals during the growing
season and timing of budbreak, shoot lengths, numbers of nodes, areas of
leaves, numbers and node positions of flowers or fruit, and fruit size were
measured. Budbreak, shoot growth, and leaf growth patterns were not clearly
related to taxonomic affinities although vines of A. deliciosa behaved
very similarly to vines of the closely related species, A. chinensis and
A. eriantha. Male and female vines differed in flowering behaviour with
male vines having higher percentages of flowering shoots, more flowering nodes
on a shoot, and often, more flowers in an inflorescence. The growth habits of
the A. chinensis and A. eriantha vines appear to be suited to
pruning and training in the same manner as A. deliciosa `Hayward'. The
selected A. arguta vines have very unfavourable growth characteristics
for commercial production, including the long vigorous shoots and sparse
flowering habit.
