| 總結: | Patchouli (Pogostemon cablin Benth) is one of species which produce
essential oil. It is known as Patchouli oil. In Indonesia, Patchouli oil is one of
important economically. It occupies an area 24.718 ha which cultivate by 65.000
farmers in Indonesia.
Yield losses from Patchouli were reported caused by global climate change
(global warming). Global warming increases the effect both of frequency and
intensity of El Nino which cause reduce rainfall. Low frequency and intensity
rainfall, and increasing of global temperature cause the drought. Patchouli is known
susceptible to drought stress.
Now, there are three cultivars which produce high essential oil (290-375
kg/ha) with patchouli alcohol content about 32 � 33 %. They are Tapaktuan,
Sidikalang, dan Lokseumawe. The aim of this research was evaluated resistance to
drought stress degree on Patchouli cultivars.
The field experiment was carried out from Nopember 2011 to Juli 2012 at the
green house Research Institute for Spice and Medicine Crop, Bogor. The
experimental design was laid-out in Randomized Completely Block Design with
three replications as block. The experiment was involved two factors. Factor one was
cultivars (Sidikalang, Lokseumawe, Tapaktuan dan Klon Bio-4). Factor two was
watering- interval (once each 1, 3 , 6 and 9 days). All data were statistically analyzed
using the analysis of variance procedure in SAS program to assess the differences of
cultivars. Duncan�s Multiple Range Test would be tested to determine the significant
differences among treatments.
The details of data recorded were soil moisture, leaf water potential, relative
water content, stomata conductivity, transpiration rate, photosynthetic rate, prolin
content, plant height, sum of leaves, leaf area, specific leaf area, leaf area ratio, total
length of root, root area, weight of root, weight of shoot, root/shoot ratio, crop growth
rate and net assimilate rate, essential oil content per plant and patchouli alcohol
content, and sensitivity index.
The result showed that watering- interval once each nine days significantly
decreased of soil moisture, relative water content, leaf water potential, stomata
conductivity, transpiration rate, photosynthetic rate, prolin content, plant height, sum
of leaves, leaf area, specific leaf area, and essential oil content per plant, and
increased root area and prolin content. Sidikalang and Lokseumawe showed more
tolerant to drought stress than Tapaktuan. The highest essential oil content per plant
showed that Loksemawe, followed by Tapaktuan and Sidikalang. Bio-4 showed that
the lowest essential oil per plant. |
