ABSTRAK<br />Pegagan (Centella asiatica L.) adalah tanaman obat yang<br />mengandung zat asiaticotik sebagai obat alzaimer dan penghalus kulit.<br />Tanaman ini telah diperbanyak sejak tahun 2000. Penelitian dilakukan di<br />Laboratorium Kultur Jaringan dan Rumah Kaca Kelompok Peneliti<br />Plasma Nutfah dan Pemuliaan, Balai Penelitian Tanaman Obat dan<br />Aromatik, Bogor dari bulan Januari 2000 sampai dengan Juni 2005.<br />Penelitian ini bertujuan untuk melihat daya multiplikasi tunas setiap<br />periode subkultur dimulai dari tahun kedua sampai periode lima tahun.<br />Media yang digunakan adalah MS + BA 0,1 mg/l. Pengamatan dilakukan<br />pada jumlah tunas, jumlah daun dan visual tunas pada umur 2, 3, 4 dan 5<br />tahun pada dua periode subkultur setiap tahunnya. Penelitian disusun<br />dengan rancangan acak lengkap, masing-masing terdiri atas 10 botol yang<br />merupakan ulangan dan setiap botol terdiri atas 1 eksplan. Untuk re-media<br />terhadap tanaman yang terlihat berubah digunakan media MS + BA (0;<br />0,1; 0,2; 0,3) mg/l. Selanjutnya untuk perakaran dilakukan pada media MS<br />+ IAA (0,1 dan 0,2); MS + NAA (0,1 dan 0,2) mg/l serta MS + IBA (0,1<br />dan 0,2) mg/l. Plantlet utuh yang terbentuk selanjutnya diaklimatisasi pada<br />media tanah + pupuk kandang dan tanah + sekam dengan perbandingan 1 :<br />1. Hasil penelitian menunjukkan bahwa daya multiplikasi tunas optimum<br />terjadi pada tahun ketiga, dan memasuki tahun keempat dan kelima<br />menurun yang diiringi dengan perubahan eksplan yang terlihat pada<br />tangkai daun yang terbentuk. Akar terpanjang dan terbanyak yang<br />terbentuk didapat pada media IAA 0,2 mg/l dengan penampilan yang<br />kurus dan rapuh. Keberhasilan aklimatisasi sangat rendah, tetapi plantlet<br />mampu beregenerasi dengan baik dan terlihat tumbuh normal. Dari hasil<br />perbanyakan terlihat bahwa jumlah anakan, jumlah daun, panjang stolon<br />dan jumlah bunga lebih tinggi dibandingkan yang tumbuh pada media<br />sekam, berturut-turut : 6,77; 7,30; 46,50 cm dan 8,31. Sementara pada<br />media sekam komponen yang dominan adalah panjang tangkai daun yakni<br />9,75 cm.<br />Kata kunci : Pegagan, Centella asiatica L., multiplikasi, tunas, aklima-<br />tisasi, penyimpanan, Jawa Barat<br />ABSRACT<br />Shoot multiplication and acclimatization of gotuloca<br />(Centella asiatica L.) five years after conservation by in<br />vitro culture<br />Gotuloca (Centella asiatica L.) is a medicinal crop containing<br />asiaticotic as alzaimer and skin revitalizer. This crop has been<br />multiplicated in vitro since 2000. This research was carried out in the<br />laboratory and glasshouse of Breeding and Germplasm Group in the<br />Indonesian Medicinal and Aromatic Crops Research Institute (IMACRI)<br />from January 2000 to June 2005. The objective of the research was to find<br />out the viability of shoots multiplication after two year to five year period,<br />with media MS + BA 0.1 mg/l. The parameters observed were the number<br />of shoots, the number of leaves at the age 2, 3, 4 and 5 years from two<br />subculture periods every year. The treatments were arranged in a<br />completely randomized design, each replication consisted of 10 bottles and<br />each bottle consisted of 1 explant. After subculture the ex-plant were re-<br />media in medium MS + BA (0; 0,1; 0,2; 0,3) mg/l. The rooting media<br />before glasshouse were : MS + IAA ( 0,1 and 0,2); MS + NAA ( 0,1 and<br />0,2) mg/l; and MS + IBA ( 0,1 and 0,2) mg/l. The plantlets formed were<br />acclimatized using soil + cattle manure and soil + rice husk with<br />comparison 1:1. Research result indicated that the optimum viability<br />multiplication was achieved in the third year, and it decreased after the<br />fourth and fifth years with change in explant forming the petiole. The<br />longest and plantlet roots were formed through media IAA 0.2 mg/l with<br />brittle and thin appearance, but the plantlets were able to regenerate better<br />and grow normal. The acclimatization was not very successful but the<br />plantlets could regenerate and grew normally. The multiplication showed<br />that the number of stumps, leaves, stolons and flowers were : 6,77; 7,30;<br />46,50 cm and 8,31 respectively. In rice husk media the dominant<br />component was pedicle length 9,75 cm.<br />Key words : Gotuloca, Centella asiatica L., multiplication, shoot,<br />acclimatization, conservation, East Jav

Trichoderma pseudokoningii has been applied as a biocontrol agent against fungal plant pathogen, such as Ganoderma boninense, the cause of stem rot disease on palm oil plants. To be more effectively applicable in the field, some experiments have been employed to formulate T. pseudokoningii in a biofungicide formulation amended with organic matter as its main nutrient resource, zealot as a carrier agent and cocoyam powder as a mixture agent. A research has been conducted to study the effect of various organic matters and their combinations in a biofungicide formulation of T. pseudokoningii on growth inhibition to G. boninense in-vitro and to obtain the best organic matters and their combinations in enhancing the growth of T. pseudokoningii and yet inhibiting G. boninense. The research has been conducted in the Laboratory of Plant Pathology, Agriculture Faculty, University of Riau from May to August 2012, using a completely randomized design consisting of 15 treatments (bagasse, rice husk, shrimp shell, dregs, and their combinations) and 3 replications. The data were statistically analyzed using analysis of variance, followed by Duncan’s New Multiple Range Test (DNMRT). The results indicated that organic matters and their combinations in the biofungicide formulation significantly affected the antagonistic capacity of T. pseudokoningii in inhibiting the growth of G. boninense in vitro. Rice husk, bagases, bagasse+rice husks, and bagasse+dregs were the best organic matters in enhancing the growth of T. pseudokoningii and its capacity to inhibit G. boninense in-vitro. It can also be concluded that shrimp shell, bagasse+shrimp shell, rice husk+shrimp shell, shrimp shell+dregs and rice husk+shrimp shell+dregs totally inhibited the growth of T. pseudokoningii in the biofungicide formulation.

ABSTRACT: The objective of this paper was to evaluate the effects of different honey concentrations in culture media, in comparison to sucrose medium, for the in vitro development of the epiphytic Encyclea cordigera orchid, in order to improve the process of propagation of the species. The in vitro germination was prepared on a reduced Murashige & Skoog (MS) medium. After 90 days, the seedlings were divided into different treatments, where they remained for another 90 days. Six treatments were set up (30g L-1 of sucrose; 15, 30, 45, and 60g L-1 of honey; and absence of any carbohydrates) in a completely randomized design. Plants were removed from the vials 270 days after the start of the experiment, and the number of roots, length of the largest leaf, length of the longest root, number of leaves, and fresh and dry masses were evaluated. Data concerning the number of leaves and roots were (x+1)1/2 transformed and subjected to an analysis of variance (ANOVA); the means were compared by a Tukey's test set at 5% probability. Medium containing 60g L-1 of honey proved to be superior to the sucrose medium traditionally used, favoring the in vitro growth and development of Encyclea cordigera. This medium can therefore be recommended for the propagation of this species, which is usually cultivated as an ornamental plant.

The propagation of Cavendish (Musa acuminata L.) seedling conventionally relatively took a longer time, not uniformed in quality and possibly has a disease that is derived from unhealthy mother stock. This research aimed to find the effect of IBA and BA on difference concentrations on the growth of plantlet, also to determine the optimum concentration of IBA and BA on the growth of Cavendish bud plantlets in vitro. This research had been carried out started from April to July 2018 in Tissue Culture Laboratory, Research Institute of Horticultural Seed Development of Pasir Banteng, Sumedang, West Java. Indonesia. The method used in this research was Completely Randomized Design with two factors. The first factor was IBA (i0 = 0 mg L-1, i1= 0,75 mg L-1, dan i2= 1,5 mg L1), and the second factor was BA (b1= 1 mg L-1 b2= 3 mg L-1 b3= 5 mg L-1 b4= 7 mg L-1), replicated three times. Duncan Multiple Range Test (DMRT) was used as a further test. The result showed an interaction between IBA and BA on the parameters of shoot growth and the number of leaves at 6 WAC. IBA showed an independent effect on the number of buds. The addition of 1,5 mg L-1 IBA and 3 mg L-1 BA was optimum for the growth of Cavendish bud explants.

Sari Perbanyakan tanaman stroberi secara konvensional dilakukan dengan menggunakan stolon, tetapi kurang efektif serta kualitas bibit yang dihasilkan kurang baik akibat adanya akumulasi penyakit. Budidaya stroberi memerlukan adanya perbanyakan bibit secara massal, tetapi tidak mengubah kualitasnya. Multiplikasi in vitro menjadi solusi untuk penyediaan bibit berkualitas dalam jumlah besar. Upaya untuk mendapatkan tunas in vitro dalam jumlah banyak yakni perlu adanya penambahan zat pengatur tumbuh golongan sitokinin seperti Benzylaminopurine (BAP) atau Thidiazuron (TDZ). Tujuan penelitian ini adalah mengetahui dan menetapkan jenis serta konsentrasi sitokinin dengan hasil terbaik dalam multiplikasi stroberi kultivar Tochiotome. Percobaan dilaksanakan di Laboratorium Kultur Jaringan Tanaman, Teknologi Benih, Fakultas Pertanian, Universitas Padjadjaran. Penelitian menggunakan Rancangan Acak Lengkap yang terdiri dari tujuh perlakuan yang diulang lima kali, yaitu: Kontrol (tanpa sitokinin); BAP (0,25 ppm; 0,50 ppm; 0,75 ppm), dan TDZ (0,25 ppm; 0,50 ppm; 0,75 ppm). Hasil dari percobaan menunjukkan bahwa penambahan sitokinin tidak berpengaruh nyata terhadap jumlah tunas dan bobot segar planlet. Media perlakuan kontrol dapat menghasilkan jumlah akar lebih banyak dibandingkan dengan media ditambah sitokinin. Penambahan BAP 0,50 ppm  berpengaruh positif terhadap jumlah daun dan dapat menghasilkan runner secara in vitro. Pemberian BAP 0,50 ppm cenderung dapat meningkatkan dan mempercepat produksi bibit tanaman stroberi kultivar Tochiotome.Kata Kunci: Benzylaminopurine (BAP), Thidiazuron (TDZ), Stroberi, Kultur Jaringan AbstractStolon is used for conventional propagation of strawberry, but it is less effective and the quality of the seeds is not good due to the accumulation of disease. In vitro multiplication becomes a solution for the supply of quality seeds in a fast time. The addition of growth regulator cytokinin, such as Benzylaminopurine (BAP) or Thidiazuron (TDZ) can produced the large number of shoot. The objective of this study was to obtain the best type and concentration of cytokinin in the multiplication of strawberry ‘Tochiotome’. The study was conducted at the Plant Tissue Culture Laboratory, Seed Technology, Faculty of Agriculture, Universitas Padjadjaran. This study used a Completely Randomized Design (CRD) with seven treatments and five replications, that were: Control (without cytokinin); BAP (0.25 ppm; 0.50 ppm; 0.75 ppm), and TDZ (0.25 ppm; 0.50 ppm; 0.75 ppm). The results indicated that addition of cytokinin did not affected increasing number of shoots and fresh weightof plantlets. Control media can produce larger number of roots than those containing PGRs, this might be due to the endogenous auxin concentrations found in strawberry plants. Also, cytokinin inhibited root formations process. Plants treated with BAP 0.50 ppm increased for the number of leaves and produced runners in vitro. This study showed application of BAP with 0.50 ppm increased and accelerated the production of strawberry ‘Tochiotome’ seedlings.Keywords: Benzylaminopurine (BAP), Thidiazuron (TDZ), Strawberry, Tissue Culture
