Effects of ultraviolet UV-B (UVB) on different varieties of quinoa. I. Effects on morphology under controlled conditions.

Effects of ultraviolet UV-B (UVB) on different varieties of quinoa. I. Effects on morphology under controlled conditions. The effects of UV-B radiation (RUV-B) on growth parameters: plant height (H), stem diameter (SD), length x wide (LW), leaf number (LN), specific leaf area (SLA) and specific leaf...

Efectos de la Radiación Ultravioleta B (UVB) sobre diferentes variedades de Quinoa. I. Efectos sobre la morfología en condiciones controladas. Perez, M. L. González, J. A. Prado, F. E. Radiación UV-B Chenopodium crecimiento. UV-B radiation Chenopodium growth. Effects of ultraviolet UV-B (UVB) on different varieties of quinoa. I. Effects on morphology under controlled conditions. The effects of UV-B radiation (RUV-B) on growth parameters: plant height (H), stem diameter (SD), length x wide (LW), leaf number (LN), specific leaf area (SLA) and specific leaf mass (SLM) of five quinoa varieties are described. RUV-B effects were different according to analyzed variety and parameter. The H was increased in CICA (P ? 0,04) and Robura (P ? 0,02) varieties, while SD was increased in CICA (P ? 0,0002) and Faro Roja (P ? 0,017) varieties. The LW changed significantly in CICA (P ? 0,05) variety only. The LN showed positive changes in all quinoa varieties exposed to RUV-B. Highest changes were found in Faro Roja (P ? 0,003), CICA (P ? 0,003) and Ratuqui (P ? 0,015) varieties. The SLM positively changed in Faro Roja, Kancolla and Robura varieties (P ? 0,05). The CICA variety showed significant increases in all evaluated parameters, followed by Faro Roja and Robura varieties. Less parameter changes occurred in Kancolla and Ratuqui varieties. The observed changes were discussed in terms of adaptive evolution. Se describen los efectos de la radiación UV-B (RUV-B) sobre algunos parámetros de crecimiento: altura de la planta (A), diámetro de tallo (DT), largo x ancho (LA), número de hojas (NH), área foliar específica (AFE) y masa foliar específica (MFE) en cinco variedades de quinoa. Los efectos de la UV-B fueron diferentes según la variedad y parámetro considerado. Así, A se incrementó en las variedades CICA (P ? 0,04) y Robura (P ? 0,02); mientras DT fue influenciado positivamente en CICA (P ? 0,0002) y Faro Roja (P ? 0,017). LA sólo mostró cambios significativos (P ? 0,05) en CICA. El NH fue la variable que experimentó cambios positivos en todas las variedades, observándose los más pronunciados en Faro Roja (P ? 0,003), CICA (P ? 0,003) y Ratuqui (P ? 0,015). La MFE cambió positivamente en Faro Roja, Kancolla y Robura (P ? 0,05). CICA fue la única variedad que experimentó incrementos significativos en todos los parámetros evaluados, seguida de Faro Roja y Robura. El menor porcentaje de cambios ocurrieron en Kancolla y Ratuqui. Las variaciones observadas se discutieron en términos de adaptación evolutiva.
