研究目的
To investigate the effects of monochromatic LEDs applied singly on the in vitro plant growth and morphogenesis, specifically focusing on tomato Lycopersicon esculentum Mill.
研究成果
Red LED light is effective for root growth and may be used as an alternative light source for in vitro plant culture systems. The study highlights the potential of LED-based light sources in regulating physiological aspects of plant growth.
研究不足
The study was limited to the effects of red LED light on tomato plant growth and morphogenesis in vitro. The potential effects of other wavelengths or combinations were not explored in depth.
1：Experimental Design and Method Selection:
The study used F1 population developed by Lycopersicon esculentum. The experiment was replicated double with specific row and plant distances.
2：Sample Selection and Data Sources:
Tomato seeds were grown in vitro under controlled temperatures.
3：List of Experimental Equipment and Materials:
Red LEDs at wavelengths of 660 nm and 640 nm powered by a self-designed driver were used.
4：Experimental Procedures and Operational Workflow:
Plantlets were exposed to a 16 h photoperiod under red LED light. The study focused on the influence of 660-nm and 640-nm light components on morphogenesis.
5：Data Analysis Methods:
Growth measurements included root length and plant height.
