suited for reproduction in the current season and provided sufficient new shoot growth to ensure a fair yield the next season. For 'Col de Damme Noire', one category (category four) showed the best 1-year-old shoot length for reproduction, both in terms of fruit number and fruit size, but the researchers cautioned that "yield on these shoots may not be optimal the next season, because current-season shoots are too short. This cultivar will require pruning to stimulate strong new shoot growth that will ensure regular, high yields", they said. In 'Noire de Caromb', category one shoots proved very productive relative to their length.

Theron noted that the results will allow researchers to develop effective pruning strategies to ensure a balance between current-season yield and the development of new fruiting wood that will guarantee regular, high yields. The findings also suggest that the three cultivars will require "differential application" of horticultural practices to attain regular, high yields of large fruit.

The researchers concluded that although not all fig cultivars bear fruit on the same shoot types, it appears as if a wide range of shoot lengths is productive.
