Lettuce Growth and Pigmentation Under Discrete Blue and Green LED Light Wavebands

A 14.6 KB dataset from figshare, authored by Masaki Kurosaki and last updated in May 2026, details an experiment on lettuce cultivars 'Rex' and 'Red Oak'. The study measured the effects of specific blue (412 nm, 425 nm, 454 nm) and green (523 nm) light wavebands on biomass, morphology, and pigment concentration. It also tested late-cycle light substitution strategies to enhance crop coloration.

Use Cases

• Modeling the relationship between specific light wavelengths and plant growth metrics like fresh weight and leaf area.
• Optimizing LED light spectra in vertical farms to balance biomass yield with desirable pigmentation (anthocyanins, chlorophyll).
• Analyzing the trade-offs between plant morphology (height, width) and pigment concentration under different blue light wavebands.
• Designing dynamic lighting schedules that substitute green light with blue light late in the growth cycle to improve visual quality.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• The description provides specific, quantified light waveband parameters (e.g., 412 nm, FWHM 16 nm).
• Experimental design is clearly described, including two distinct objectives and two lettuce cultivars.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (14.6 KB), indicating limited scope.
