Background: Salvia miltiorrhiza Bunge, a medicinal plant belonging to the Lamiaceae family, is commonly used as a health-promoting tea in China. This study investigated and analyzed the improvements in S. miltiorrhiza growth, external quality, vegetation indices, and photosynthetic performance through photoperiod control.
Methods and Results: The study was conducted with four different photoperiods: 8, 12, 16, and 24 hours of light period (h·d-1). The results showed that the 12 h·d-1 - 16 h·d-1 photoperiods were most effective for promoting shoot growth. This was determined by evaluating plant sizes, shoot biomass; various remote sensing vegetation indices including normalized difference vegetation index, photochemical reflectance index, and modified chlorophyll absorption ratio index; and five chlorophyll fluorescence parameters (Fv/Fm, ΦDo, ABS/RC, DIo/RC, and PIABS). Similarly, the root growth, root biomass, and external quality parameters (CIELAB color space values and visual score) indicated that a 12 h·d-1 - 16 h·d-1 photoperiod was the most effective. Conversely, continuous light conditions for 24 h·d-1 photoperiod significantly decreased most growth parameters and both shoot and root external qualities, suggesting inefficiency in such conditions.
Conclusions: Therefore, the study recommends cultivating S. miltiorrhiza under a 12 h·d-1 - 16 h·d-1 range photoperiod to improve the growth, external qualities, and physiological characteristics.
