Previous studies have demonstrated that light quality critically affects plant development and growth; however, the response depends upon the plant species. This research aims to examine the effects of different light wavelengths on sunflower () sprouts that were stimulated during the night. Natural light and narrow-band light-emitting diodes (LEDs) were used for an analysis of sunflower sprouts grown under full light and specific light wavelengths. Sunflower seeds were germinated under different light spectra including red, blue, white, and natural light. Luminosity, temperature, and humidity sensors were installed in the plant nursery and remotely monitored and recorded by an Internet of Things (IoT) device. The experiment examined seed germination for seven days. The results showed that the red light had the most influence on sunflower seed germination, while the natural light had the most influence on the increase in the root and hypocotyl lengths.
先前的研究表明，光质对植物的发育和生长有至关重要的影响；然而，这种反应取决于植物的种类。本研究旨在研究不同波长的光对夜间受刺激的向日葵芽的影响。自然光和窄带发光二极管（LED）用于分析在全光和特定光波长下生长的向日葵芽。向日葵种子在包括红光、蓝光、白光和自然光在内的不同光谱下进行发芽。在植物苗圃中安装了亮度、温度和湿度传感器，并通过物联网（IoT）设备进行远程监控和记录。该实验观察了种子发芽七天的情况。结果表明，红光对向日葵种子的发芽影响最大，而自然光对根和下胚轴长度的增加影响最大。
