摘要

文心蘭（Oncidium Gower Ramsey）種植於台大人工氣候室30/25℃、25/20℃、20/15℃及威諾型溫室中以不同濃度的肥料處理（J+P：各盆每週輪施原濃度Johnson氏完全營養液及Peter's 1.0g/l一次、J：每週各盆施原濃度Johnson氏完全營養液一次、1/2J：每週各盆施1/2濃度Johnson氏完全營養液一次及1/4J：每週各盆施1/4濃度Johnson氏完全營養液一次。），觀察其假球莖生長與開花的情形。試驗結果假球莖的長度隨著試驗溫度的降低而減低，寬度及厚度則隨著試驗溫度的降低而增加。但各溫度中不同的肥料濃度處理，對假球莖的長度、寬度及厚度則影響不大。開花品質方面，低溫（20/15℃）可增加花序的分枝性及小花朵數，而各溫度中不同的肥料濃度處理，對植株開花的情形及花序發育的狀況則無明顯的差異性。

This study was to investigate effects of temperature and fertilizer concentration on the growth of pseudobulb and development of inflorescence in Oncidium Gower Ramsey. Plants grown in phytotron with day/night temperature 30/25℃、25/20℃、20/15℃ and Venlno glasshouse and treated by different fertilizer concentrations. The height of pseudobulb decreased when temperature decreasing, but the width and thickness were increased when temperature decreasing. Fertilizer concentration didn't have statistical significance in the growth of height, width and thickness of pseudobulb. Lower temperature (20/15℃) increased the number of branches and florets of inflorescence. There were no statistical significance in flowering and development of inflorescence between fertilizer concentrations.
