MetadataShow full item record
Most strains of Mentha species have 1-20% l-limonene and 0.5-8% 1,8-cineole with the total of the two components seldom exceeding 25-30%, but 19 individuals having more than 50% limonene-cineole were found in a progeny of 10,000 Strain 2 M. citrata--M. crispa F1 hybrids(MURRAY and LINCOLN 1970). Two other high limonene-cineole individuals were found in a progeny of 113 Strain 2 M. citrata--Strain 1 M. aquatica F1 hybrids. The purpose of the present research was to determine the genetic basis for the 57-94% limonene-cineole content of the 21 strains.
