Abstract
The aim of this study was to explore how various spectra of complementary light impact the growth and development of strawberry plants under stress conditions caused by salinity and alkalinity. The experiment involved cultivating plants in a greenhouse with ambient light, subjecting them to blue (460 nm), red (660 nm), blue/red (1:3), and white/yellow (400-700 nm) light at different developmental stages. Stress treatments included control (without stress), alkalinity (40 mM NaHCO3), and salinity (80 mM NaCl). Results indicated a decrease in dry weights under salinity and alkalinity stress. The blue and red spectra were more effective in mitigating stress effects compared to other spectra. While stress conditions led to a reduction in SPAD, blue light increased SPAD under stress. Stress conditions decreased RWC, and blue/red light increased RWC under stress conditions. Blue/red and white/yellow light had the most significant impact on reproductive traits. Salinity and alkalinity stress reduced OJIP curves compared to the control, but the blue and red spectra increased OJIP curves under their respective stress conditions. In conclusion, manipulating the supplemental light spectrum can alleviate the effects of salinity and alkalinity stresses, suggesting the potential extension of artificial light use in stress conditions.
