| Abstract: | A
study was carried out to determine the effect of transplanting date on the
essential oil composition of rose-scented geranium (Pelargonium graveolens L’Herit. ex Ait.) cultivar
‘CIM-Pawan’ under hill conditions of Uttarakhand,
India. The
crops were raised using five months of transplanting, viz. December, January,
February, March and April. The oil was extracted by hydro-distillation and
analyzed by capillary gas chromatography. The main components of the oil were
citronellol (21.3-28.7%), geraniol (23.1-38.4%), linalool (4.2-6.5%), iso-menthone (6.5-7.9%), citronellyl
formate
(6.3-8.3%), 10-epi-γ-eudesmol
(4.7-5.6%) and geranyl formate (3.3-4.3%). The results indicated that the
essential oil components were affected significantly by transplanting time. The
citronellol/geraniol ratio (C: G), quality determining factor was found to vary
from 0.55 to 1.16 in these oils which was well within the desired limit.
Nevertheless, oil with best C:G ratio was obtained from January (0.99) and
February (0.92) planted crops; showing the effect of crop duration. |
