Horticulturae, Journal Year: 2025, Volume and Issue: 11(3), P. 287 - 287

Published: March 6, 2025

Basil (Ocimum basilicum L.) is highly sensitive to environmental conditions and an ideal candidate for cultivation in controlled environment agriculture (CEA). Light-emitting diode technology has become essential CEA, offering precise control over light intensity, spectrum, duration. This study investigated how supplemental blue light, far-red or their combination influences basil biomass, morphology, texture, color when added a white + red spectrum. ’Prospera’ ’Amethyst’ were exposed five treatments 14–28 days: at 180 µmol∙m−2∙s−1 (W) as the control, four with additional 60 of either (+W60), (+B60), (+FR60), B FR (+B30+FR30), total photon flux density 240 µmol∙m−2∙s−1. The results demonstrated that +B60 +W60 increased leaf thickness by 17–20% compared +FR60 treatment. Conversely, texture analysis revealed +FR60-treated leaves had higher puncture resistance, requiring 1.57 ± 0.43 N 1.45 0.35 force, respectively, 1.19 0.32 1.1 0.21 under +B60. These findings suggest tailored recipes CEA can optimize quality, allowing growers modify traits like color, thickness, toughness.

Horticulturae, Journal Year: 2025, Volume and Issue: 11(3), P. 326 - 326

Published: March 16, 2025

Thanks to its numerous uses in gastronomy, pharmaceuticals, and cosmetics, basil (Ocimum spp.) is one of the most studied consumed aromatic plants worldwide. However, commercialization availability are limited by short post-harvest shelf-life, primarily due strong sensitivity cold, poor handling, consequent microbial contamination. This review provides a comprehensive overview latest research on pre-harvest techniques that can extend shelf-life basil, aiming offer practical tool for growers, distributors, retailers, scientists. In addition influencing plant’s primary metabolism, factors, such as genotype selection, plant nutrition, irrigation, light management, have direct impact quality shelf-life. Unlike previous reviews, which focus strategies, this work structured analysis factors directly influence basil’s By integrating recent findings nutrient environmental conditions, we framework guide future agronomic practices aimed at minimizing losses enhancing product quality.

Alteration in Light Spectra Causes Opposite Responses in Volatile Phenylpropanoids and Terpenoids Compared with Phenolic Acids in Sweet Basil (Ocimum basilicum) Leaves

Journal of Agricultural and Food Chemistry, Journal Year: 2022, Volume and Issue: 70(39), P. 12287 - 12296

Published: Sept. 20, 2022

Basil (Ocimum basilicum, cv. Dolly) grew under three different light spectra (A, B, and C) created by light-emitting diode lamps. The proportions of UV-A, blue, green-yellow wavelengths decreased linearly from A to C, the red far-red increased C. Photosynthetic photon flux density was 300 μmol m-2 s-1 in all spectra. spectrum C plants had highest concentrations phenolic acids (main compounds: rosmarinic acid cichoric acid), lowest emissions phenylpropanoid eugenol terpenoids linalool 1,8-cineole), dry weight, water content. Conversely, B caused higher terpenoid lower acids. High peltate glandular trichomes explained high emissions. growth secondary compounds affecting aroma taste can be modified altering spectra; however, increasing phenylpropanoids decreases vice versa.
