PENGARUH JENIS KEMASAN TERHADAP MUTU DAN PERTUMBUHAN SETEK NILAM BERAKAR (Pogostemon cablin Benth) SELAMA PENYIMPANAN

MELATI MELATI, DEVI RUSMIN

Abstract


ABSTRAK
Penanganan benih yang baik sangat diperlukan untuk mempertahan-
kan viabilitas benih nilam yang dikirim ke daerah yang jauh dari kebun
induk. Benih yang tidak dikemas dengan baik akan berakibat menurunnya
viabilitas benih dengan cepat, sehingga pada saat ditanam benih tidak
dapat tumbuh (mati). Untuk itu telah dilaksanakan penelitian yang
bertujuan untuk mengetahui pengaruh jenis kemasan setek berakar
terhadap pertumbuhan nilam. Percobaan dilaksanakan di rumah kaca Balai
Penelitian Tanaman Obat dan Aromatik (Balittro) dari bulan Desember
2004 sampai dengan Maret 2005. Percobaan disusun dalam rancangan
acak lengkap (RAL) terdiri atas tujuh perlakuan dengan 3 ulangan.
Perlakuan yang diberikan adalah : (1) setek nilam dibalut tissue dan
dibungkus plastik transparan, (2) setek nilam dibalut koran dan dibungkus
plastik transparan, (3) setek nilam dibalut cocopeat dan dibungkus plastik
transparan, (4) setek nilam dibalut tissue dan dibungkus karung plastik, (5)
setek nilam dibalut koran dan dibungkus karung plastik, (6) setek nilam
dibalut cocopeat dan dibungkus karung plastik, (7) kontrol (setek tidak
dibalut dan tidak dibungkus). Hasil percobaan menunjukkan bahwa
persentase hidup setek berakar nilam yang disimpan selama 7 hari pada
semua kemasan kecuali kontrol masih tinggi yaitu >90%. Hampir dari
seluruh parameter pertumbuhan (tinggi tanaman, jumlah tunas dan jumlah
daun) yang diamati menunjukkan pengemasan setek nilam dibalut tissue
dan dibungkus plastik transparan lebih baik dibandingkan dengan
pengemasan setek yang lain.

ABSTRACT
Effect of packing materials on the quality and growth of
patchouli rooted cuttings
Good seed handling should be carried out seriously to maintain the
cutting viability of pacthouli especially when the cutting distributed to
other region far away from the seed garden. Improper cutting packing will
decrease of viability the cutting very fast and when it is planted the cutting
will not grow.Therefore, the research was conducted to find out the effect
of packing material on the growth of rooted cutting. The experiment was
conducted in the green house of the Indonesian Research Institute for
Aromatic and Medicinal Crops Bogor from December 2004 to March
2005, and it was arranged completely in a randomized design (CRD) with
3 replications, consisted of 7 packing treatments. The treatments were : (1)
rooted cuttings wrapped using transparent plastic with tissue media, (2)
rooted cuttings wrapped using transparent plastic with newspaper media,
(3) rooted cuttings wrapped using transparent plastic with cocopeat media,
(4) rooted cuttings wrapped using plastic sack with tissue media, (5) rooted
cuttings wrapped using plastic sack with newspaper media, (6) rooted
cuttings wrapped using plastic sack with cocopeat media, (7) control
(unwrapped seedling). The results indicated that after 7 days of storage,
rooted cuttings of patchouli were still viable (>90%) in all treatments
except control. Packing of rooted cuttings by wrapping it with transparent
plastic with tissue media showed the best growth with more number of
leaves and higher plant compared to other packing treatments.
