幼果期富士苹果树体各器官钙定量分析

对幼果期矮化富士苹果树体各器官及其皮层、木质部的生物量、钙含量和钙累积量进行了研究。结果表明，单株干重为10．21kg，皮层和木质部干重分别为2．14和7．07kg，骨干枝干重为各器官之首；各器官钙含量差异显著，根系平均钙含量高于地上部多数器官，中央干皮层钙含量最高；单株钙累积量为76．67g，皮层和木质部钙累积量分别为52．44和13．83g，直径1．0-5．0cm根的钙累积量最高。

Analysis of calcium distribution in different organs of young fruit for Fuji apple tree

Red Fuji apple trees of young fruit time were used as materials in the experiment. The biomass of trees and the calcium content and accumulation of the cortex and the xylem were studied in this paper. The result indicated that the biomass of trees were 10.21 kg, the dry weight of the cortex and the xylem were 2.14 and 7.07 kg, respectively. The dry weight of scaffold was the head of the various organs. Calcium content was difference remarkable. Calcium content of the roots was higher than the most organs of above ground parts. Calcium content of the central leader of cortex was highest. The calcium accumulation of tree was 76.67 g. The calcium accumulation of the cortex and the xylem were 52.44 and 13.83 g, respectively. It was the root of the diameter from 1.0 to 5.0 cm that the calcium accumulation was highest.
