1980年生长季中,对嫁接在MM106上的8年生旭苹果树,进行了五次取样(休眠期、盛花期、盛花后三周、7月中旬和采收期)。把整株树分成:树干、骨干枝、一年生枝、二年生枝、三年生枝、短枝、新梢、新梢叶、短枝叶、花簇和果实。在每一取样期都测定了各部份的总表面积和干重。采收时,全树的干重比休眠期大124％。所累积干物质的分配,木质内47.8％,叶内19.1％,果实内33.1％。叶幕于花后三周形成。在采收期,叶子的总叶面积是木质组织表面积的13倍。
During the 1980 growing season, five samples (dormant, full bloom, full bloom, mid-July, and harvest) of 8-year-old Asahwa apple trees grafted on MM106 were performed. The whole tree is divided into: trunk, trunk branches, annual branches, biennial branches, three-year branches, short branches, shoots, shoots new leaves, short leaves, flower clusters and fruits. The total surface area and dry weight of each part were determined at each sampling period. Harvest, the whole tree dry weight than the dormant period of 124%. The distribution of accumulated dry matter was 47.8% in wood, 19.1% in leaves and 33.1% in fruits. The leaf curtain formed three weeks after anthesis. At harvested time, the total leaf area of the leaves is 13 times the surface area of the woody tissue.
