No information is available on
the effect of composition of the biomass in terms of plant parts
distilled on the quality of the essential oil in these crops. This
information should be useful for producing the required quality
of the essential oil for different end-uses. We studied the effect
of the composition of the aerial biomass in terms of plant parts
distilled on the quality of the essential oil in three clones of rosescented geranium which differed for aerial biomass yield, essential
oil content and essential oil composition. The results are presented
