於人工氣候室以日/夜溫35/30℃、30/25℃、25/20℃、20/15℃、15/13℃五種溫度及無溫控之塑膠棚簡易設施栽培無嵌紋病毒之綠竹高壓苗10 個月，探討綠竹葉、枝桿、地下莖及根部等各部位主要營養元素之濃度及分配特性。結果顯示，竹株氮、磷、鉀三種營養元素濃度之排序均以鮮葉最高，其次依序為枝桿、地下莖、根及落葉。鮮葉中氮素濃度為21.2-28.9 mg·g-1，磷濃度1.1-1.5 mg·g-1，鉀濃度19.9-22.5 mg·g-1。與鮮葉相比，落葉中鈣、鎂濃度高，而氮、鉀濃度低。鮮葉之鈣濃度為7.1-8.4 mg·g-1，鎂濃度3.5-5.2 mg·g-1。以營養元素濃度排序，在鮮葉中氮＞鉀＞鈣＞鎂＞磷；在枝桿、地下莖及根部則為鉀＞氮＞鈣＞鎂＞磷；在落葉為鈣＞
氮＞鎂＞鉀＞磷。新鮮葉片中氮之濃度與葉綠素計讀值之間呈顯著直線正相關(R2N
＝0.85, P＜0.01)。鮮葉中之磷、鉀、鈣及鎂等元素濃度與竹株出筍數之關係均呈顯著直線正相關，但氮元素濃度與出筍數則呈顯著線性負相關。

The temperature effect on the contents and distribution of macro-nutrients in leaf, branch & culm, rhizome and root of green bamboo (Bambusa oldhamii Munro) were studied. Mosaic virus-free green bamboo layers were grown under six temperature treatments for ten months. The treatments included five day/night temperatures, i.e. 35/30 , 30/25 , 25/20 ℃ ℃ ℃, 20/15℃ and 15/13℃ in the phytotron and one at a plastic tunnel in the field as control. The results showed that the fresh-leaf had the highest concentrations of N, P and K elements, followed by branch & culm, rhizome, root and litter-leaf in decreasing order. The N, P and K concentrations in fresh leaf were 21.2-28.9 mg·g-1, 1.1-1.6 mg·g-1, and 19.9-22.5 mg·g-1, respectively. The litter-leaf had very high concentrations of Ca and Mg, but low amount of N and K as compared to the fresh leaves, branch & culm, rhizome and root. The Ca concentration in fresh leaf was 7.1-8.4 mg·g-1 and Mg content was 3.5-5.2 mg·g-1. The concentrations of macro-nutrients were in the order of N＞K＞Ca＞Mg＞P in fresh-leaf, K＞N＞Ca＞Mg＞P in branch & culm, rhizome and root, and Ca＞N＞Mg＞K＞P in litter-leaf. The N concentrations in fresh-leaf and SPAD values had a significant linear relationship(R2 N＝ 0.85, P＜0.01). Significant linear correlations also existed between the leaf concentrations of P, K, Ca, Mg respectively and the number of shooting. An inverse relationship was found between the concentration of N in fresh-leaf and the number of shooting.
