Polyphenol levels in two cotton (Gossypium hirsutum L.) callus cultures

Abstract

We study the production of polyphenols by callus cultures from two cultivars of cotton (Gossypium hirsutum L.). Coker 312 produces the best calli and has embryogenic potential contrary to that of R405-2000, which is non- embryogenic. There is a relationship between the level of phenolic compounds and the callus cultures. Callogenesis in Coker 312 is highly correlated to a higher content of catechin, caffeic acid, ferulic acid, rutin, o—coumaric acid and salicylic acid. On the other hand, the cinnamic acid derivates (trans-cinnamic, cis and trans—methoxycinnamic acids) found in high amounts in R405-2000 calli could have a negative influence on the induction of cotton callogenesis. © 2009, Taylor & Francis Group, LLC.
