研究目的
To determine the effects of different ratios of blue and red LEDs on the growth characteristics, morphological changes, photosynthetic pigment contents, and antioxidant activities of C. lentillifera, and to examine whether the PDS gene plays a protective role or causes damage under different LED light sources.
研究成果
Red and blue LEDs had positive effects on the growth and antioxidant activity of C. lentillifera, respectively. A mixture of red light with a low proportion of blue light enhances both growth and yield in closed macroalga production systems.
研究不足
The study focused on indoor cultivation conditions, and the effects might vary under natural conditions. The long-term effects of blue light on C. lentillifera were not fully explored.
1：Experimental Design and Method Selection:
The study involved growing Caulerpa lentillifera under six LED light treatments to assess effects on weight gain, pigment content, antioxidant activity, and PDS gene expression.
2：Sample Selection and Data Sources:
Healthy samples of C. lentillifera were provided by Chensheng Aquatic Products Technology Co., Ltd. and cultured under controlled conditions.
3：List of Experimental Equipment and Materials:
LED lamps with specific spectral distributions, LI-COR spherical quantum sensor, high-performance liquid chromatograph, spectroradiometer, and other laboratory equipment were used.
4：Experimental Procedures and Operational Workflow:
C. lentillifera was grown under different LED light treatments, and parameters like weight gain, pigment content, and gene expression were measured over 12 days.
5：Data Analysis Methods:
Statistical analysis was performed using one-way ANOVA and Tukey tests to analyze differences among treatments.
