MOYA, María E.; REINOSO, Patricia D.; GALUSSI, Alberto A.  e  SOLDA, Gerardo. Reply to Phenol of Caryopses of Barley and Rye Cultivars. Cienc. docencia tecnol. [online]. 2006, n.32, pp.243-251. ISSN 1851-1716.

The phenol technique is a tool that enables differentiating cultivars according to the coloring manifested by florets and caryopses at exposition for a period of time with phenol vapor. In barley and rye, the time of exposition or the color adopted by the florest or the caryopses have not been established. The goal to characterize barley and rye cultivars by their response to phenol was posed. In barley, after a 24-hour exposition to phenol at 1%, three different coloring patterns were determined: very light brown, light brown and mixed (dark brown florets up to those with a very light stain) and in rye, the exposition was 4 hours, with dark brown being the predominant color in caryopses.
