چکیده انگلیسی
Light acting as elicitor or stress inducer, it plays a pivotal role in all developmental processes of plant providing necessary building blocks for growth and primary and secondary metabolites production. The main objective of the current study was to investigate the individual effect of colored lights on developmental processes and production of polyphenolics contents in Brassica rapa. In this study, the red and white lights (control) were found to be the most effective sources for seed germination (91%) in Brassica rapa. Similarly, red light enhanced radicle growth (102â¯mm), while green light suppressed radicle growth (60â¯mm) as compared to control (67â¯mm). The red light also promoted the plumule growth (50â¯mm) as compared to control (37â¯mm). The maximum biomass gain (67â¯mg) was observed under red light as compared to control (55â¯mg). Currently, the maximum total phenolics content (9.49â¯mg/g-DW) and phenolics production (379.616â¯mg/L) was observed under the influence of blue lights as compared to control (0.23â¯mg/g-DW and 8.91â¯mg/L). Similarly, the blue lights also enhanced the biosynthesis of total flavonoids content (2.2611â¯mg/g-DW) and flavonoids production (90.44â¯mg/L) as compared to control (0.0318â¯md/g-DW and 0.8268â¯mg/L). The current results represents that red and blue lights are the most effective sources for plantlets development and production of polyphenolics content in Brassica rapa.
