Dry Weight Partitioning of ‘McIntosh’ Apple Trees1
Year: 1983
Type: article
Abstract: Eight-year-old ‘McIntosh’/Malling-Merton (MM) 106 apple trees ( Malus domestica Borkh.) were sampled 5 times (dormant, full bloom, full bloom + 3 weeks, mid-July, and harvest) during the 1980 growing season. Whole trees were separated into: trunk; scaffold branches; 1-, 2-, and 3-year-old wood; spurs; new shoots; shoot and spur leaves; and blossom clusters or fruits. Total surface area and dry weight were determined for each fraction on each sampling date. Total tree dry weight at harvest was 124% greater than the dormant weight. The distribution of the accumulated dry matter was 47.8% in wood, 19.1% in leaves, and 33.1% in fruit. Leaf canopy development was complete 3 weeks after bloom. The surface area of the leaves at harvest was 13 times that of the woody tissues.
