In contrast, energy sources such as UV-A radiation often produce adverse and potentially harmful effects. In this study, we evaluated the influence of different light spectra and UV-A radiation on the <em>in vitro</em> germination and early development of tomato cv. Cherry seedlings (<em>Solanum pimpinellifolium</em>), including shoot length, root length, and fresh and dry biomass. Our results showed that germination rates did not differ among the evaluated light spectra or darkness; however, UV-A radiation proved to be extremely detrimental. Darkness promoted the greatest shoot elongation, while red and green spectra yielded the highest root lengths. The green spectrum resulted in the greatest fresh biomass accumulation, whereas the yellow, green, and dark treatments produced the highest dry biomass. Consistently, UV-A radiation was the most harmful factor across all evaluated parameters. Overall, the appropriate selection of light spectra can enhance germination and morphophysiological performance in tomato cv. Cherry seedlings grown <em>in vitro</em>, whereas exposure to UV-A radiation should be strictly avoided during germination and early development.</p> Guilherme Rafael do Prado, Douglas Augusto Gaspio, Matheus Vinícius Abadia Ventura, Antonio Carlos Pereira de Menezes Filho Copyright (c) 2026 Guilherme Rafael do Prado, Douglas Augusto Gaspio, Matheus Vinícius Abadia Ventura, Antonio Carlos Pereira de Menezes Filho https://creativecommons.org/licenses/by/4.0/ https://periodicos.cerradopub.com.br/cerrado/article/view/817 Thu, 01 Jan 2026 00:00:00 -0300
