Roem.& Schult. ]具特別的株形和豐富的花型花色，深受歡迎。然而亟待建立沙漠玫瑰穴盤育苗期間之適溫與水養分管理標準，以加速整齊生產。本研究探討溫度、養液氮濃度、氮型態、磷濃度、鉀濃度及介質體積含水量對沙漠玫瑰‘Harry Potter’生長之影響，以供栽培參考。 Radermachera hainanensis and R. sinica are important indoor foliage plants with dark glossy green leaves, and low-light tolerance. However, the information on plug production and subsequent management of shading and medium volumetric water content (VWC) of potted plants is still unclear. Therefore, the objectives of this study were to determine the effects of light intensity and nutrient solution strength, nutrient solution nitrogen, phosphorus, potassium concentration, and nitrogen form on the growth of both species during plug stage and the effects of shading and medium VWC on growth after transplant. Desert rose [Adenium obesum (Forssk.), Roem. & Schult.] is a popular flowering potted plant due to its attractive sculptural caudex with a wide range of flower colors. However, nutrition management during slow and long plug production has not yet been well established. This study aimed to determine the effects of temperature, nutrient solution nitrogen, phosphorus, potassium concentration, and nitrogen form, and volumetric water content on growth of A. obesum ‘Harry Potter’.海南菜豆樹;山菜豆;沙漠玫瑰;遮光;溫度;養液氮濃度;氮型態;介質體積含水量;Radermachera hainanensis ; R. sinica; shading; medium volumetric water content;temperature; nutrient nitrogen concentration; nitrogen form
