本文对白蚁（Coptotermes formosanus Shiraki）和真菌（Fomitopsis palustris（Berkeley et Curtis）Murrill（FFPRI 0507）和Trametes versicolor（L.不包括法国）Quel（FFPRI 1030）]对毛竹（Phyllostachys pubescensMazel）自由葡萄糖和淀粉含量的季节性和高度性变化。游离葡萄糖含量在秋冬季节普遍低于春夏季节，而淀粉含量在8月份最低，到2、3月份含量呈线性上升趋势。在高度相关波动方面，随着取样高度的增加，游离葡萄糖含量有降低的趋势。有没有特殊的相关性之间的游离葡萄糖或淀粉含量和白蚁的消费，即使在竹喂白蚁比在木材喂养的白蚁获得更高的死亡率。然而，在4米和8米的高度从底部的腐烂真菌的样品的游离葡萄糖含量和质量损失之间的正相关性进行了观察。对于淀粉，没有发现对真菌攻击的影响。
The potential of termite (Coptotermes formosanusShiraki) and fungal attacks [Fomitopsis palustris(Berkeley et Curtis) Murrill (FFPRI 0507) andTrametes versicolor(L. ex Fr.) Quel (FFPRI 1030)] against moso bamboo (Phyllostachys pubescensMazel) were evaluated with regard to the seasonal and height-dependent changes of the free glucose and starch contents, which were measured by a newly developed method. The free glucose contents were generally lower in autumn and winter than in spring and summer, whereas the lowest starch contents were obtained in August, and the contents increased almost linearly up to February and March. In terms of the height-dependent fluctuation, the free glucose contents tended to decrease as the sampling heights increased. There was no special correlation between the free glucose or starch contents and the consumption by termites, even though higher mortalities were obtained in the bamboo-fed termites than in the wood-fed termites. However, a positive correlation between the free glucose contents and mass losses of the samples at 4-m and 8-m heights from the bottom by the decay fungi was observed. For starch, no influence on fungal attack was found.
