The patterns of fruit grouwth, abscission and dry matter accumulation were determined for ungirdled for macadamia branches and compared with the pattens on girdled branches. The relationships between fruit set,fruit drop, and the number of avaliabre leaves were also assessed. Approximately 50 leaves were riquired to support development of each fruit on girdled branches, so that final fruit numbers on girdled brancheswere higher or lower than on ungirdled controls, depending on leaf numbers. High leaf numbers did not cause any increase in size on girdled branches, but low leaf numbers resulted in fruit volumes up to 23% lower that the controls. The number of fruits set on ungiedled branches was independent of leaves on the branche. Defoliation of ungirdled branches had no affect on the number of fruits set, with fruit set on these branches apparently being supoported almost entirely from carbohydrate obtained elsewhere in the tree. Three phases of fruit drop were odserved, with maxima at 2, 6-7, and10 weeks post-anthesis, separated by phases of relatively low fruit drop at 4 and 8 weeks post-anthesis. The maximum dry weight increase of the crop occured between 10 and 20 weeks post-anthesis, when there was very little fruit drop.Therefore, although limited availability of assimilates may influence fruit retention in macadamia, there is no simple relationship between structural carbon and fruit drop. |
