1.
The contents of metal ions in sapwood are higher than those in heart wood.
结果发现在实验范围内，各种木材原料中都存在由多种金属离子构成的复杂体系；不同种原料中金属离子的含量和成分存在着很大差异；针叶木Ｆｅ、Ｍｎ 含量显著，高于阔叶木；同种原料中，边材金属离子含量一般高于心材；不同生长环境会导致木材金属离子分布出现差异。
2.
The transformation of sapwood to heartwood is an important physiological process in most tree species.
以东北东部山区温带森林的7个主要组成树种——红松、兴安落叶松、春榆、水曲柳、胡桃楸、黄菠萝和蒙古栎为研究对象,比较分析各树种心材和边材的生长特征。
3.
Experimental results showed that the sap flux density(SFD) of the middle sapwood was higher than the outer and inner;the daily SFDs of different sizes of trees diameter had similar pattern,the bigger trees had higher SFD than the smaller trees due to the difference in size of root system;the mean daily.
结果表明:加勒比松边材不同位点的液流密度由外到内呈低—高—低的态势;观测期间林分日液流密度变幅为411~4 120 L。
