Polifenoles en casos de deficiencia inducida de hierro

[EN] The process of iron induced chlorosis has been studied in connection with the polyphenol formation in leaves of pear-tree. Polyphenols are formed after chlorophyll and their formation is conditioned to the amount of chlorophyll protector present in the leaf. The possible role to be played by th...

spelling Polifenoles en casos de deficiencia inducida de hierroHeras Cobo, Luis[EN] The process of iron induced chlorosis has been studied in connection with the polyphenol formation in leaves of pear-tree. Polyphenols are formed after chlorophyll and their formation is conditioned to the amount of chlorophyll protector present in the leaf. The possible role to be played by the quinone-polyphenol system is discussed in connection with the mechanism for protection of the chlorophyll. The reduction from quinone to polyphenol may be carried out by means of the ferrous compound, present as a consequence of the protection of the chlorophyll. The possible conditions for the formation of necrotic brown substances are briefly discussed.[ES] La formación de polifenoles es posterior a la aparición de clorofila en el proceso de corrección de la clorosis por aporte de hierro y parece condicionada por la cantidad de protector de la clorofila presente en la hoja. Se discute el posible papel que pudiera tener el sistema quinona-polifenol en relación con el mecanismo de protección de la clorofila, considerando que la reducción de quinona a polifenol puede realizarse por intervención del compuesto ferroso formado como consecuencia de dicha protección. Se discuten brevemente las condiciones posibles para la formación de productos pardos necróticos.Peer reviewedCSIC - Estación Experimental de Aula Dei (EEAD)201120111960info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/37132reponame:DIGITAL.CSIC.
