Results of this study are as follow.Some bamboo species such as non-clump forming type arid clump forming type were selected as a material of this Study, but Madake is the most useful bamboo specia in Japan, so detail research on photosynthesis were conducted through this specia. (1) Seasonal change of light-photosynthesis curve got satulation at l000mumol/m^3/s PAR and 7-l0mumol/m^3/s photosynthesis, and the same result obtained even a day light-photosynthesis curve. (2) Seasonal change of Pn is tha there is a peak between summer and autumn, and end of March and early April follow this, and minimum lies May. Duration of minimum Pn is the same period of fall leaves and elongation of culm, eventually, this duration need much water supply for growth of new shoot. (3) Seasonal change of dark respiration also showed the same tendency of Pn. (4) Respiration decreased between December and early february for the reason of coldness, and end of May also decleased, because of leaves change from old one to new one.Mentioned above photosynthesis and the growth of bamboo has corelation each other, and it is possible to produce more production of bamboo by tending and management of stand.

本研究的主要结果如下：本研究选择了不成丛型和成丛型等竹种作为研究材料，但Madake是日本最有利用价值的竹种，因此本研究对该竹种的光合作用进行了较为详细的研究。(1)光-光合曲线的季节变化在PAR为1000 μ mol/m^3/s、光合速率为7- 10 μ mol/m^3/s时达到饱和，即使是白天的光-光合曲线也得到了同样的结果。(2)净光合速率的季节变化为夏秋之间有一个高峰，3月底4月初为高峰，5月为最低。Pn最低的持续时间与落叶期和伸长期相同，这一持续时间最终需要大量的水分供应来促进新梢的生长。(3)暗呼吸的季节变化也表现出与Pn相同的趋势。(4)12月至2月上旬，由于寒冷，呼吸量减少，5月下旬由于老叶换新叶，呼吸量也减少，说明光合作用与竹子的生长是相互联系的，通过林分的抚育管理，可以提高竹子的产量。
