1·Increasing and decreasing of stored starch are closely related to the periodicity of cambial activity.
淀粉储量的消长与形成层活动周期有很强的相关关系。
2·The variability of esterase isozyme activity in the vascular tissues was in consistent with the periodicity of cambial activity.
酯酶同工酶的酶谱和酶活性亦随形成层的活动状态发生变化。
3·Starch grains decreased progressively after cambial activity was resumed in early spring until they disappeared in all the stem tissues.
早春形成层恢复活动后，淀粉贮量逐渐减少直至消失。
4·Between primary xylem and primary phloem there are 2-3 layers of parenchymatous cells, regularly or irregularly arranged, but no cambial zone can be recognized.
初生木质部与初生韧皮部之间可见到2—3层排列规则或不规则的薄壁组织细胞，但是没有维管形成层的发生。
5·The variations of polysaccharide content and zymogram and activity of peroxidase, esterase and amylase isozyme were related to the periodicity of cambial activity.
过氧化物酶、酯酶和淀粉酶的同工酶酶谱及活性，以及多糖颗粒的贮量都随形成层活动周期的变化而变化。
6·Wood is the product of cambial activity in trees, and the seasonal activity style of cambium directly influences wood biomass production, structures and properties.
木材（次生木质部）是树木形成层细胞分化的产物，形成层的活动方式不仅影响木材的产量，而且影响木材的结构和性质。
7·POD was mainly distributed in the radial walls of the cambial cells and expanding xylem cell, especially at the corner of cell wall and cell wall close to the primary pit field.
形成层细胞阶段和伸展生长阶段，POD主要分布在径壁上，尤其是细胞壁角隅处和初生纹孔场附近的细胞壁。
