2.1. Plant material
Three clones of rose-scented geranium viz., Indian cultivar, ‘Bourbon’ and two somaclones, ‘Narmada’ and ‘LTC-2’, both
obtained from ‘Bourbon’, were used in the study. The essential oil
of ‘Bourbon’ resembles the ‘Reunion’ geranium oil (International)
of commerce for citronellol: geraniol ratio (≈1:1) but because of its
relatively low content of 6,9 guaiadiene and high content of 10-epi--eudesmol than ‘Reunion’ geranium oil, it is considered as ‘African’
geranium oil, in trade. ‘Narmada’ has similar aerial biomass yield
as ‘Bourbon’ but, in comparison with ‘Bourbon’, has low contents
