Effects of B ultraviolet radiation (UV-B) on different varieties of Quinoa. II. Effects on the synthesis of photosynthetic and protective pigments and soluble sugars under controlled conditions.

An architectural study of the genus Gutierrezia Lag. was carried out, and seven different models were established. Differences in architecture between North American and South American species are pointed out. A key to differentiate the models is provided.

Efectos de la radiación ultravioleta B (UV-B) sobre diferentes variedades de Quinoa: II.- efectos sobre la síntesis de pigmentos fotosintéticos, protectores y azúcares solubles en condiciones controladas. Prado, F. E. Perez, M. L. González, Y J. A. Asteraceae Astereae Gutierrezia arquitectura de plantas Asteraceae Astereae Gutierrezia plant architecture An architectural study of the genus Gutierrezia Lag. was carried out, and seven different models were established. Differences in architecture between North American and South American species are pointed out. A key to differentiate the models is provided. Se describen los efectos de la UV-B sobre la síntesis de pigmentos fotosintéticos (clorofila total, clorofila a, clorofila b, carotenoides), protectores (compuestos absorbentes de UV-B) y azúcares solubles (glucosa, fructosa y sacarosa) en cinco variedades de quinoa de diferentes orígenes geográficos. En general, se demuestra que las variedades reaccionan desplegando diferentes estrategias para protegerse de la radiación UV-B. Estas estrategias pueden ser de tipo morfológico, fisiológico y/o bioquímico. Una respuesta común, observada en las cinco variedades fue el incremento en el contenido de compuestos absorbentes de UV-B, lo que puede interpretarse como un “escudo químico” de protección para el aparato fotosintético frente al exceso de energía proveniente de la radiación quese aplica a las plantas.
