Abstract

ABSTRAKKeladi tikus (Typonium flagelliforme Lodd.) Blume merupakantanaman obat yang bermanfaat dalam mengobati penyakit kanker. Secarakonvensional, tanaman ini diperbanyak vegetatif sehingga keragamangenetiknya tergolong sempit. Upaya peningkatan ragam genetik keladitikus telah dilakukan melalui variasi somaklonal yaitu kultur kalus dandiperoleh plantlet yang normal, namun belum dievaluasi keragamanmorfologi, komponen pertumbuhan, produksi, mutu dan skrining fitokimiatanaman. Penelitian bertujuan untuk mengetahui keragaman morfologi,pertumbuhan, produksi, mutu dan fitokimia tanaman hasil kultur kalustersebut. Kegiatan dilakukan di rumah kaca Balai Penelitian TanamanObat dan Aromatik mulai November 2005 sampai Januari 2007. Bahantanaman yang digunakan adalah benih keladi tikus asal kultur kalus.Sebagai pembanding digunakan benih keladi tikus asal kultur jaringan dankonvensional. Bahan tanaman tersebut ditanam di dalam polibagberukuran 20 cm x 30 cm yang berisi media tumbuh campuran tanahdengan pupuk kandang sapi (2:1), dan dipelihara di rumah kaca sampaiberumur sembilan bulan. Rancangan yang digunakan adalah acak lengkapdengan enam belas ulangan. Setiap ulangan terdiri atas satu polibag.Parameter yang diamati adalah karakter morfologi dan pertumbuhan padaumur enam bulan sedangkan produksi umbi diamati pada umur sembilanbulan. Selain itu, juga dilakukan analisis terhadap mutu dan fitokimia dariumbi. Hasil penelitian menunjukkan bahwa secara visual tanaman asalbenih kultur kalus memiliki karakteristik morfologi yaitu bentuk daun,bentuk batang, warna daun dan batang serta bentuk umbi yang samadengan benih asal kultur jaringan maupun benih konvensional. Komponenpertumbuhan (jumlah anakan) benih asal kultur kalus dari kutur jaringanlebih sedikit dari benih konvensional. Sedangkan jumlah daun, panjangdan lebar daun tidak berbeda. Tinggi tanaman asal benih kultur kalus lebihpendek dari benih kultur jaringan dan konvensional. Produksi umbi hasilkultur kalus (14,24 g) dan hasil kultur jaringan (15,11g) lebih tinggi dariumbi konvensional (7,0 g). Analisis mutu (kadar sari larut dalam air) padakeladi tikus asal benih kultur jaringan lebih tinggi dari benih asal kulturkalus dan benih konvensional. Senyawa steroid ditemukan pada tanamanasal benih kultur kalus dan kultur jaringan, namun senyawa flavonoid dantriterpenoid terdeteksi dalam jumlah tinggi pada tanaman asal benihkonvensional. Hasil ini menunjukkan bahwa penerapan teknik keragamansomaklonal pada tanaman keladi tikus hanya meningkatkan variasi mutudan fitokimia tetapi tidak pada morfologi tanaman.Kata kunci : Keladi tikus, Typonium flagelliforme (Lodd.)

Blume derived from somaclonal variationRodent tuber (Typonium flagelliforme Lodd.) Blume is one ofmedicinal plant which is used for healing cancer. Conventionally, the plantwas vegetatively propagated, therefore. Its genetic variation is narrow. Anattempt to increase the genetic variation of plant was conducted usingsomaclonal variation (calli culture) and resulted the normal planlet in vitro.But, the plant morphology, growth, production, quality and fitochemistryvariation have not been evaluated yet. The aim of the research were toobtain the morphological variation, growth, production, quality andfitochemistry of rodent tuber from calli culture seeds. Experiment wasdone at the Indonesian Medicinal and Aromatic Crops Research InstituteGreen house from November 2005 to January 2007. The plants materialused were seeds of rodent tuber from calli culture compared with seedsfrom in vitro culture. They were planted in the polibag (20 cm x 30 cm)which is contained soil and cow manure (2:1) and maintained until ninemonths. The experiment was arranged in completely randomized designwith sixteen replications. The parameters observed were morphologicalcharacter and growth component at six months and rhizome production atnine months. Further more, quality and fitochemical variation and rhizomewere also analyzed. The result showed that visually, morphologicalcharacter of those plant observed were same in leaf, stem and rhizome.Growth component (number of leaves, length and width of leaves) of seedsfrom calli culture were same with in vitro and conventional but plantheight was different. Conventional seeds produced the greatest tillers butrhizome production was lower than seeds from calli and in vitro. Watersoluble extract from in vitro seeds was higher than calli culture andconventional seeds. Steroid compound was detected in seeds from calliand in vitro. On the otherhand, flavonoid and triterpenoid were not found.The experiment showed that application of somaclonal variation on rodenttuber only increase the quality and fitochemical variations but not on plantmorphology.Key words : Typonium flagelliforme (Lodd.)

ABSTRAKKeragaman  genetik  plasma  nutfah  jahe  rendah  sehingga  perlu dilakukan  peningkatan  keragaman,  antara  lain  dengan  iradiasi sinar gamma. Penelitian ini bertujuan untuk mengetahui pengaruh dosis iradiasi terhadap pertumbuhan dan produksi jahe putih kecil.  Penelitian dilakukan di Laboratorium Balai Penelitian Tanaman Rempah dan Obat serta Kebun Percobaan Cicurug, Sukabumi pada bulan Juni 2010 sampai dengan Mei 2011. Iradiasi dilakukan di P3TIR, BATAN, Jakarta. Percobaan disusun menggunakan rancangan split plot dengan petak utama dua aksesi jahe putih kecil ZIOF 0048 dan HALINA 1 dan anak petak adalah 11 dosis iradiasi (0-50 Gy) dengan interval 5 Gy. Perlakuan diulang sebanyak tiga kali. Pengamatan karakter morfologi dilakukan secara kuantitatif dan kualitatif pada umur 2, 3, dan 4 BST. Hasil penelitian menunjukkan aksesi berpengaruh terhadap radiosensitivitas. Aksesi HALINA 1 lebih sensitif dibandingkan   dengan   ZIOF 0048   ditunjukkan   dengan   nilai   LD50 HALINA 1 (11,07 Gy) lebih rendah dari LD50 ZIOF 0048 (13,43 Gy). Interaksi aksesi pada dosis 5 dan 10 Gy memiliki nilai terbaik pada  tinggi tanaman, ukuran daun serta jumlah anakan. Dosis mempengaruhi tinggi tanaman, ukuran daun, diameter dan panjang batang, serta jumlah daun. Pertumbuhan tanaman semakin meningkat dengan bertambahnya umur tanaman. Namun, semakin tinggi dosis iradiasi, pertumbuhan tanaman semakin melambat.  Pertumbuhan tanaman terbaik diperoleh pada dosis 5 Gy, dan tidak berbeda dengan kontrol. Bobot dan ukuran rimpang terbaik (964 g/rumpun) diperoleh dari HALINA 1 pada dosis 10 Gy, dan berbeda dengan kontrol (454 g/rumpun), serta perlakuan lainnya.Kata kunci:  Zingiber officinale var. amarum, iradiasi sinar gamma (60Co), keragaman genetik, mutasi, karakter morfologi. The Effect of Gamma Irradiation (60Co) on the Growth and Production of Small White Ginger (Zingiber officinale var. amarum)ABSTRACTGenetic variability of ginger germplasm was low, therefore it was necessary to broaden genetic variability using gamma irradiation. This research aimed to see the effect of irradiation on the growth of small white ginger. This study was conducted in the Plant Breeding Laboratory, Indonesian Spice and Medicinal Crops Research Institute and the Cicurug Experimental Garden Sukabumi from June 2010 to May 2011. Irradiation was undertaken in P3TIR, BATAN, Jakarta. The experiment was arranged in a split plot design with the main plot was two accessions HALINA 1 and ZIOF 00 48, and the sub plots was 11 irradiation doses (0-50 Gy) with 5 Gy interval.  The experiment was replicated three times.  Parameters observed were quantitative and qualitative characters at 2,3 and 4 months after   planting (MAPs).   Results   showed   that   accession   influenced radiosensitivity. Accession HALINA 1 was more radiosensitive than ZIOF 0048, indicated by LD50 of HALINA 1 was 11.0693 Gy, lower than ZIOF 0048 13.4254 Gy. Interaction between accessions at 5 and 10 Gy showed the highest plant height, leaf size, and number of shoots. Irradiation dose affected plant height, leaf size, stem diameter and length, and number of leaf. The plant growth increased in conjunction with plant age, but the higher irradiation dose, the growth of plants slowed down. The best plant growth was obtained from 5 Gy, not different from control. The highest rhizome weight (964 g/plant) was obtained from HALINA 1 treated with 10 Gy, differ from control (545 g/plant) and the other treatments.Keywords:  Zingiber officinale var. amarum, gamma irradiation (60Co), genetic variability, mutation, morphological characters.

Abstract

ABSTRAKTujuan penelitian ini untuk mengetahui pengaruh pemberian harapada berbagai tingkat dan frekuensi pemberian air terhadap pertumbuhandan produksi lada perdu. Penelitian dilakukan di rumah atap InstalasiPenelitian Cimanggu, Balai Penelitian Tanaman Rempah dan Obat, tahun1996-1998. Penelitian dilakukan dengan menggunakan pot drum 40 liter.Penelitian menggunakan rancangan acak kelompok berukuran 6tanaman/petak yang diulang 3 kali. Terdapat 2 faktor yang diuji yaitukombinasi dari tingkat dan frekuensi pemberian air dan faktor keduaadalah takaran hara NPK Mg 12-12-17-2. Hasil penelitian menunjukkanbahwa pemberian air 21 mm/2 hari, setara dengan curah hujan 3.780 mmper tahun dengan pemberian pupuk 400 g NPKMg 12-12-17-2 pertanaman per tahun menghasilkan pertumbuhan terbaik dan produksitertinggi yaitu 42,7 g/tanaman pada produksi tahun pertama dan 171,2g/tanaman pada tahun produksi kedua. Ini berarti dengan jarak tanam1,25 x 1,25 m telah mampu dicapai hasil lebih dari 1,09 ton/ha. Tingkatpencucian hara makro tertinggi terjadi pada perlakuan pemberian air 21mm/2hari dengan agihan pemupukan 600g/tanaman/tahun.Kata kunci : Lada perdu, Piper nigrum L., pemupukan, pemberian air,produksiABSTRACTNutrient leaching and intake in bushy pepper (Pipernigrum L.) at different rates and frequency of wateringThe objective of the research was to find out the effect offertilizing at different rates and frequency of watering on the growth andyield of bushy pepper. The research was done at a shading house ofCimanggu Experimental Farm, Indonesian Spices and Medicinal CropsResearch Institute in 1996 – 1998. Bushy pepper was planted in acontainer of 40 litre in Cimanggu Instalation. The research used arandomized block design with 3 replication, 6 plants/ plot. There weretwo factors studied in the research i.e. the combination of the rate andfrequency of watering, and the rate of NPK Mg 12-12-7-2. The resultsshowed that watering at 21 ml in 2 days, equals to 3780 mm rainfall, withthe application of 400 g NPK Mg 12-12-17-2 per plant gave the bestgrowth performance and the highest yield of pepper 42.7 g/vine at the 1 styear and 171.2 g/vine at the 2 nd year. It means that at the plant spacing of1.25 x 1.25 m the plants can produce 1.09 tones/ha. The highest nutrientleached happened at the treatment of watering of 21 mm/2days withfertilizer application 600 g/vine.Key words: Bushy pepper, Piper nigrum L., fertilizing, watering,growth, production

Abstract

Evaluation on the resistance of kenaf accessions (Hibis¬ cus cannabinus /..) to Fusarium oxysporum SchlectResistant variety is one of the most important components controlling of fusarium wilt disease on kenaf caused by Fusarium oxysporum Schlect. To ind out resistant variety an evaluation on kenaf accessions was conducted in the laboratory and screen house of Phytopathology, RITFC, Malang in June-December 1997. The results of the selection on 77 accessions showed that 41 accessions were highly resistant, 1 2 accessions were resistant, 7 accessions were moderate, 12 accessions were susceptible, and 5 accessions were highly susceptible Three resistant and highly resistant accessions were namely 85-9-73, DS/005 H, and FJ/004 He could inhibit F. oxysporum growth about 23.40- 32.43 mm and its discolorisation about 0.0-13.4%.

Abstract

ABSTRAKPenelitian untuk mendapatkan klon-klon unggul rami untuk lahan diantara pohon kelapa, telah dilaksanakan pada bulan April 1999 - Maret2000, di lahan kebun plasma PIR-Kelapa 5 (NES 5) Desa Mekarsari,Kecamatan Cimerak, Kabupaten Ciamis, Jawa Barat. Tanaman kelapahibrida ditanam pada tahun 1993/1994 dengan jarak tanam 9 m x 9 m, dansudah berproduksi. Perlakuan terdiri dari 12 klon rami yang disusun dalamrancangan acak kelompok dan diulang 3 kali. Klon-klon tersebut adalahPujon 10, Pujon 13, Bandung A, Pujon 9, Pujon 902, Indochina, Kotaraja,Japan I, Hakuki, Padang 3, Jawa Timur 3-0 dan Pujon 601. Bibit/rhizomaditanam dengan jarak tanam 50 cm x 80 cm satu stek per lubang, pada plotberukuran 4 m x 9 m. Kapur dan pupuk kandang diberikan bersamaandengan pengolahan tanah dengan dosis masing-masing 2 ton dan 20 tonper hektar. Sedangkan pupuk buatan diberikan pada 10 hari setelah tanamdengan dosis 200 kg urea + 150 kg SP-36 + 100 kg KC1 per hektar.Pemupukan selanjutnya dilakukan 7-10 hari setiap sehabis panen/pangkasdengan dosis yang sama. Panen pertama dilakukan pada 70 HST,sedangkan panen berikutnya setiap dua bulan sekali. Pengamatan padasebelum dan sesudah panen dilakukan terhadap tinggi tanaman, diameterbatang, jumlah anakan per rumpun, bobot brangkasan segar, bobot batangsegar dan bobot kering china grass. Hasil penelitian menunjukkan bahwaklon Pujon 10, Pujon 13, Padang 3, Bandung A dan Indochina merupakanklon-klon yang memiliki daya adaptasi tinggi di lahan antara pohon kelapadi Ciamis sampai dengan panen ke empat.Kata kunci: Rami, Boehmeria nivea L.
