(1) Background: According to the IUCN, is classified as a vulnerable species. However, knowledge of its seed characteristics and germination behaviour is lacking. (2) Methods: The aim of this research was to characterise the seeds and evaluate the effects of seed colour and controlled temperatures on seed germination. The seeds were segregated into the following colour categories: light brown (LB), brown (B), and dark brown (DB). The seeds were evaluated under controlled constant temperatures (23 °C) and at room (fluctuating) temperature independently. One-way ANOVA, -test, and germination indexes were used for analyses. (3) Results: The results showed significant differences in the mean seed masses of LB, B, and DB seeds. Similarly, the differently coloured seeds varied in their water imbibition rates. The result showed significant differences in the mean germination of the seeds in both the controlled temperature (23 °C) and room-temperature chambers among the LB, B, and DB seeds. However, the -test revealed no significant differences in the mean germination of the seeds of similar colours between controlled temperature and room temperature conditions. (4) Conclusions: The seed's colour significantly influenced the seed mass, water imbibition capacity, and germination rate relative to the temperature treatment. Dark brown seeds are recommended for seed collection aimed at seedling propagation.
(1) 背景：根据国际自然保护联盟（IUCN）的分类，[物种名称未给出]被列为易危物种。然而，对其种子特性和萌发行为的了解尚缺。(2) 方法：本研究旨在表征种子特性，并评估种子颜色和控制温度对种子萌发的影响。种子被分为以下颜色类别：浅褐色（LB）、褐色（B）和深褐色（DB）。种子分别在控制恒温（23°C）和室温（波动温度）下进行评估。采用单因素方差分析、t检验和萌发指数进行分析。(3) 结果：结果表明，LB、B和DB种子的平均种子质量存在显著差异。同样，不同颜色的种子在吸水率方面也有所不同。结果显示，在控制温度（23°C）和室温培养箱中，LB、B和DB种子的平均萌发率存在显著差异。然而，t检验表明，在控制温度和室温条件下，相似颜色种子的平均萌发率没有显著差异。(4) 结论：相对于温度处理，种子颜色对种子质量、吸水能力和萌发率有显著影响。建议收集深褐色种子用于幼苗繁殖。
