Pruning and trellising purple passion fruit. I. Yields and seasonal trends.
In an experiment in which one-wire and 3-wire trellising as well as severe, selective, light and no pruning were compared, it was found that pruning did not increase yields or reduce the usual decline in yield over a 3-year period although light and selective pruning both increased the life of the vine at very low productivity. Trellising did not influence yield. Fruiting peaks occurred in January-February and September-October.
