Morphogenetic, Ontogenetic and Diurnal Variabilities of Turkish Oil-Bearing Rose (Rosa damascena Mill.)
Abstract
Morphogenetic, ontogenetic and diurnal variabilities for essential oil content and
components of oil-bearing rose (Rosa damascena Mill.) were studied in this research at the Süleyman
Demirel University, Rose and Rose Products Research and Implementation Center in 2009. The
flowers were hand-collected at five different development stages (from budding to full-flowering),
four different times of the peak flowering date (06:00, 10:00, 14:00 and 18:00 h) (1st June) and four
dates during the flowering season (25th May, 1st June, 8th June and 15th June), and separated into
petals and sepals for analyses of essential oil content by hydro-distillation with a Clevenger-type
apparatus and components by GC/MS. The essential oil contents of the petals and sepals were 0,057%
and 0,013%, respectively, while the whole flowers contained 0,035%. The petal oils had more
monoterpenes geraniol (36,9%), citronellol (26,7%) and nerol (14,9%), and less methyl eugenol
(0,4%). The flowers contained the highest essential oil (0,045%) when the petals were with cupshaped
and the stamens bright-yellow as group stage 4. During the flowering season for 4 weeks, the
highest essential oil content (0,045%) was in the third week, the highest geraniol content (42,4%) was
in the first week, and the highest citronellol content (37,7%) was in the last week. From 06:00 to
18:00 h during the day, the essential oil content decreased from 0,055% to 0,017%, and also the rates
of citronellol (up to 14:00 h) and methyl eugenol decreased and the rates of geraniol and nerol
increased.
