摘要:

In March 1988, Cyclone Bola caused much flooding in kiwifruit orchards near Gisbome, New Zealand. In Paper 1 (Reid et aI. 1991) we described a survey of flood affected orchards, and considered factors influencing early vine decline(i.e., premature autumn defoliation in the first 11 weeks following the flood). Here we report the effects of the flooding upon performance of the same vines in the following season (October 1988-May 1989). Foliage vigour and trunk growth were closely related to foliage stress in the preceding autumn. One third of the vines suffered early decline. Four teen percent of the vines died; most of these bad shown early decline. Those which survived symptoms of early decline showed poor foliage vigour and trunk growth the following season. Foliage vigour was positively related to feeder root health. Vines surviving symptoms of early decline yielded 26% less mass and 24% fewer fruit than those which showed no early decline. Compared to vines showing adequate vigour, vines with poor vigour in spring 1988 yielded 77% less fruit mass and 69% fewer fruit per vine. It is probably uneconomic for growers to attempt to save vines which show early declinefollowing waterlogging events.
