BACKGROUND: Light quality is a controllable signal in protected horticulture that can shift rose petal color and scent. However, how defined blue:red (B:R) ratios jointly influence pigment composition, vacuolar pH, and volatile organic compounds (VOCs) across development remains not fully understood.
RESULTS: Rosa hybrida 'Juicy Terrazza' plants were grown under six LED spectra (CK, B, R, 1B1R, 1B2R, 2B1R) in a randomized complete block design (RCBD; n = 3 blocks). A moderately blue-enriched spectrum (2B1R) increased late-stage yellowness (b*) and carotenoid accumulation at S4, whereas red and red-biased spectra favored anthocyanin accumulation. Vacuolar pH differed among treatments at S3-S4 and showed associations with color coordinates. VOC profiling at S4 within a fixed sampling window revealed spectrum-dependent compositional shifts, including enrichment of apocarotenoid-related volatiles under 2B1R. Transcript analyses showed stage-dependent regulation of flavonoid and carotenoid pathway genes, with the largest treatment divergence at S2.
CONCLUSIONS: Defined B:R ratios reshape warm-toned rose traits through coordinated changes in pigment pools, vacuolar pH, and, at S4, VOC profiles, supporting spectral strategies that target specific developmental windows to optimize ornamental quality.
