Controlling lethal browning of Hemarthria compressa tissue cultures

摘要

Hemarthria compressa is an important warm-season I forage grass for use in Southwest China. However, due to I poor seed set, it is propagated by vegetative cuttings of stolons, rhizomes, and nodal sections. The in vitro propagation of H. compressa isstill faced with difficulties including blackening or browning of tissues prior to culturing due to the oxidation of phenolic compounds by polyphenolic oxidase enzyme present in excised tissue (Yang et al. 2008). The objectives of the study were to investigate possible means of successful initiation of cultures through elimination of phenolic browning.
