Abstract

ABSTRAKInduksi perakaran merupakan tahapan yang sangat penting dalam pembentukan benih secara in vitro. Perbanyakan stevia (Stevia rebaudina) secara konvensional melalui setek atau biji terkendala pada tingkat keberhasilan, keseragaman, dan produksi rendah. Perbanyakan inkonvensional melalui kultur jaringan telah berhasil dilakukan sampai dengan tahap multiplikasi tunas. Keberhasilan tersebut perlu didukung dengan inisiasi akar melalui induksi dengan penambahan zat pengatur tumbuh. Penelitian ini bertujuan untuk mengukur respon stevia terhadap zat pengatur tumbuh induksi perakaran in vitro. Penelitian dilakukan sejak Maret sampai Agustus 2012 di laboratorium kultur jaringan Balittro dan Kebun Percobaan Manoko. Bahan tanaman yang digunakan adalah tunas aseptik stevia dari kultur yang berumur tiga bulan pada media penyimpanan MS + B 0,1 mgl-1. Tunas stevia dikulturkan pada media MS dengan penambahan IAA (0,1; 0,2; dan 0,3) mg l-1, IBA (0,1; 0,2; dan 0,3) mg l-1, dan NAA (0,1; 0,2; dan 0,3) mg l-1. Rancangan penelitian yang digunakan adalah Acak lengkap dengan sepuluh ulangan. Parameter yang diamati adalah jumlah dan tinggi tunas, jumlah dan panjang akar, dan tingkat keberhasilan aklimatisasi. Hasil penelitian menunjukkan bahwa penambahan NAA 0,2 dan 0,3 mg l-1 memacu pertumbuhan jumlah akar terbaik. Pada tahap aklimatisasi, persentase keberhasilan masih rendah dan perlu didukung dengan kondisi lingkungan yang optimum.Kata kunci: Stevia rebaudina, induksi perakaran, in vitro, auksin

Abstract

ABSTRAKAnis (Pimpinella anisum L.) merupakan tanaman herba tahunanyang termasuk ke dalam famili Umbelliferae. Buahnya diketahuimengandung minyak atsiri yang didominasi senyawa trans-anethol (90%)dan berkhasiat sebagai antiseptik, antispasmodik, antikanker, karminatif,pelega tenggorokan, obat bronkitis, serta digunakan dalam pembuatansabun, parfum, pasta gigi, juga krim kulit. Sebagai tanaman bernilaiekonomi, upaya perbanyakan anis perlu dilakukan. Perbanyakan secara invitro dengan teknik kultur jaringan merupakan salah satu metode alternatifyang dapat digunakan untuk menghasilkan bibit dalam jumlah banyak,seragam dan dalam waktu yang relatif singkat. Dengan penambahansitokinin sintetik tipe urea seperti thidiazuron (TDZ) dan tipe purin sepertibenzil amino purin (BAP) akan memacu inisiasi dan proliferasi tunas.Penelitian ini bertujuan mendapatkan media yang tepat untuk menginduksitunas anis yang optimal dengan penambahan BAP atau TDZ, mengetahuirespon pertumbuhan dan penampakan kultur akibat penambahan berbagaikonsentrasi BAP atau TDZ, serta mempelajari sinergisme yang terjadiantara keduanya. Pada tahap inisiasi, eksplan berupa tunas pucuk diinduksidi dalam media MS padat dengan penambahan BAP (0,1 mg/l; 0,2 mg/l;0,3 mg/l; 1 mg/l; 2 mg/l; 3 mg/l), atau TDZ dengan kisaran konsentrasiyang sama. Tunas terbanyak yang dihasilkan dari dua jenis sitokinin padatahap ini disubkultur ke dalam media yang ditambahkan jenis sitokininyang berbeda (TDZ ke BAP atau BAP ke TDZ) pada konsentrasi 0,3 mg/latau 3 mg/l. Pada media yang ditambahkan TDZ dihasilkan tunas anislebih banyak (3,62-6,28) dibandingkan pada media yang ditambahkanBAP (1,86-2,78), tetapi tunas yang dihasilkan pendek (roset). Sedangkantunas yang dihasilkan dalam media yang ditambahkan BAP beruas lebihtinggi tetapi jumlah tunasnya sedikit. Subkultur tunas anis ke dalam mediayang diperkaya dengan sitokinin yang berbeda meningkatkan jumlah tunasyang berproliferasi dan memperbaiki visual tunas.Kata kunci: Anis, Pimpinellla anisum L. ,  minyak atsiri, multiplikasi tunas,in vitro, TDZ, BAP, Jawa BaratABSTRACTApplication of purine and urea types of cytokinins inshoot multiplication of Anise (Pimpinella anisum L.) invitroPimpinella anisum L. or sweet anise is an annual–herbaceous plantbelongs to the Umbelliferae family. The fruit of anise contains of essentialoil, which is mainly consisted of trans-anethol (90%). Essential oils ofanise is mainly used as an antiseptic, antispasmodic, anticancer,carminative, expectorant and has also been used as component in soap,perfumery, tooth paste, and skin cream productions. Since this crop ismainly cultivated in sub tropical region, anise cultivation in Indonesia hasnot been performed. To obtain sufficient numbers of anise plantingmaterials in vitro propagation was conducted by applying benzyl aminopurine (BAP) and thidiazuron (TDZ). In this research TDZ or BAP wereapplied at various concentrations (0,1 mg/l: 0.2 mg/l; 0.3 mg/l; 1 mg/l; 2mg/l; 3 mg/l), to induce shoots in MS-solid culture media. The highestnumber of shoots obtained in those two type of cytokinins containingmedia from the initiation stage were subcultured into the mediasupplemented with different cytokinins (TDZ to BAP or BAP to TDZ) at0.3 mg/l or 3 mg/l levels. The results showed that medium with theaddition of TDZ resulted in higher numbers of shoot (3,26-6,28) than thatof medium with an addition of BAP (1,86-2,78). However, rosette shootswere dominant in TDZ containing medium. On the other hand, mediumwith an addition of BAP resulted in less numbers of shoots with tallernodes. Subculture of anise into different kinds of cytokinins increased thenumbers of proliferated-shoots and recovered the abnormal shoots.Key words : Anise, Pimpinellla anisum L, essential oils, shootsmultiplication, in vitro, TDZ, BAP, West Java

Abstract

This study was performed to evaluate the development of somatic embryo from embryogenic calli of ginger meristem culture. Completely randomized design was applied, replicated 4 times. Embryogenic calli from meristem tissue of inner shoot bud of rhizome obtained on MS medium containing 100 mg/L glutamine, 2% sucrose with the addition of 1.0 mg/L 2,4-D and 3.0 mg/L BA, were subjected to proliferation medium, MS and N basal media containing 3% mannitol. Then, transferred into somatic embryo maturation medium, either MS or N basal media supplemented with 6% sucrose. The number of somatic embryos-formed significantly affected by the proliferation medium applied. The highest number of somatic embryos (about 82.0 per 1 g friable calli) was achieved on the MS medium, 4 weeks after incubation. In addition, the optimum growth of embryogenic calli containing somatic embryos was obtained on MS and N medium supplemented with 6% sucrose. There were significantly difference between the media applied (MS and N ) to somatic embryos maturation. The highest number of mature somatic embryos (57.2 embrios) was achieved on the MS medium, 18 days after incubation.

Abstract

Effects of Indole Butyric Acid and Naphtaleine Acetic Acid on the root-induction of pyrethrum [Chrysanthemum cinerariifolium (Trevir.)Vis.] clone Prau 6 in vitroPyrethrum is one of botanical pesti-cides producing plant that has beneficial va-lue to be improved as the substitution of syn-thetic pesticide, which is considered to be harmful for both of human and environment. In order to obtain a sufficient planting mate-rial, in vitro propagation had been performed. Rooted-shoots derived from in vitro cultured adapted better than that of un-rooted one, when transplanted into the field (acclima-tization). Therefore, in this research root in-duction of pyrethrum clone Prau 6-in vitro-shoots were conducted by applying Indole Butyric Acid (IBA) and Naphtaleine Acetic Acid (NAA). Experiment was arranged in a single factor Completely Randomized Design with 10 replications. The treatment tested was an application of synthetic auxins (IBA or NAA) into MS medium in 5 different level of concentrations (0.2; 0.4; 0.6; 0.8; 1.0 mg/l), and control (without auxin). The parameters observed were time to root-initiation, number and length of root, and root characteristic, at 6 weeks after subcultured. The results showed that application of IBA or NAA into MS me-dium significantly affected to the root initia-tion time, number of root, length and charac-teristic of the root, 6 weeks after subcultured. Induced-root on the medium containing 0.2 mg/l IBA showed a better characteristic as compared to others treatments with rounded-form, shorter initiation time (12.5 days), large amount of root (14.1) and longer (1.47 cm).

Abstract

The availability of seeds with known sex types is one of the obstacles in nutmeg cultivation. Epicotyl grafting using rootstocks aged 20–30 days is one of the solutions to overcome this issue. The objective of this study is to determine the optimal stage/age of rootstocks and the number of leaves of the scion to improve the success rate of nutmeg through epicotyl grafting. The experimental design used is a Randomized Block Design (RBD) with factorial pattern, repeated three times. The first factor is the stage of rootstock age, categorized as: 1 month (without leaves), 2 months (2 leaves), 3 months (3 leaves), and 4 months (4 leaves). The second factor is the number of leaves on the scion : 2 leaves cut in half, 2 leaves, and 3 leaves. Variables observation i.e. : a) C/N ratio in the rootstock and scion before grafting, b) plant morphology (Number of leaves, shoot length, shoot diameter, number of branches, and plant height.), and c) plant physiology (grafting success rate, graft union length, photosynthesis rate, and leaf chlorophyll content). The results showed that all rootstock stages and scion leaf number could be used for nutmeg grafting, with a 67-100% success rate. The best recommendation treatments are rootstocks with two leaves grafted to scions with two leaves, and rootstocks with four leaves grafted to scions with three leaves.
