Abstract

Pertumbuhan dapat diartikan sebagai suatu pertambahan bagian-bagian sel. Adanya     pertumbuhan sel biasanya dapat diketahui dengan adanya pertambahan ukuran dan     pembelahan sel. Populasi sel khususnya mikroba  secara kuantitatif atau kualitatif dapat digunakan untuk memantau atau mengkaji fenomena pertumbuhan.Enzim inulinase (E.C. 3.2.1.7) adalah enzim yang mampu merombak substrat inulin menjadi monomer fruktosa. Fruktosa merupakan bahan baku (doctoring agent) untuk proses  pembuatan FOS, IOS, pulullan, aseton dan sorbitol.Tujuan  penelitian ini adalah untuk mengetahui kinetika kecepatan pertumbuhan specifik (µ), waktu generasi (g) dan aktivitas inulinase yang dihasilkan oleh fusan F7.  Fusan F7 merupakan hasil fusi antara Pichia manshurica dan Rhodosporidium paludigenum.Hasil penelitian menunjukkan bahwa Fusan F7 mempunyai kecepatan pertumbuhan specific (µ)  sebesar 0.3299 jam dengan waktu generasi (g) 2.1012 jam dan aktivitas enzim inulinase yang dihasilkan sebesar  0.5337 IU. Hasil tersebut  terletak diantara kedua parentalnya yaitu P. manshurica (µ= 0.27935 jam; g = 2.4815 jam dan aktivitas = 0.557 IU) dan Rh. paludigenum (µ= 0.3787 jam; g = 1.8304 jam dan aktivitas = 0.3263 IU). Kata kunci : Pertumbuhan;  fusan F7; inulinase ; umbi dahlia

Abstract

Perbaikan teknik perbanyakan dan mutu bibit klonal karet (Hevea brasiliensis Muell Arg) dapat dilakukan melalui teknik kultur jaringan. Kendala teknik tersebut diantaranya masih tingginya intensitas browning pada tahap inisiasi kalus. Browning umumnya disebabkan oleh senyawa fenolik yang biasanya muncul dan terakumulasi ketika eksplan dilukai. Penelitian ini bertujuan mengetahui metode eliminasi browning yang efektif diantara perlakuan perendaman eksplan dalam asam askorbat, arang aktif+sukrosa, subkultur berulang yang diinkubasi dalam ruang gelap dan terang. Bahan eksplan yang digunakan adalah eksplan midrib daun klon karet PB 330 yang ditanam pada media induksi kalus MS+2,4-D 5 ppm. Masing-masing menggunakan 10 botol sebagai ulangan dan ditanam sebanyak 2 eksplan per botol. Pengamatan meliputi waktu awal browning, waktu rata-rata eksplan mengalami browning, intensitas browning dan jumlah eksplan browning hingga 35 hari setelah tanam (HST). Data dari 10 eksplan untuk masing-masing perlakuan selanjutnya dianalisis dengan analisis ragam dari Rancangan Faktorial dan uji lanjut dengan Duncan Multiple Range Test untuk data yang berbeda nyata. Hasil percobaan menunjukkan bahwa perendaman eksplan dalam 100 mg/L asam askorbat steril selama 30 menit, yang diinkubasi dalam ruang gelap efektif menurunkan intensitas browning hingga 7,5% dengan jumlah eksplan yang mengalami browning dapat ditekan hingga 30%. Diterima : 6 Januari 2016 / Direvisi : 30 Mei 2016 / Disetujui : 24 Juni 2016 How to Cite : Admojo, L., & Indrianto, A.

Abstract

Kultur embrio anggrek secara in vitro pada media tumbuh yang sesuai akan menghasilkan tanaman anggrek dalam jumlah besar namun dalam waktu yang singkat. Tujuan penelitian ini adalah untuk mengetahui jenis dan konsentrasi pupuk organik cair (POC) yang efektif terhadap pertumbuhan dan perkembangan embrio anggrek Vanda limbata  Blume x Vanda tricolor Lindl. Percobaan dilakukan dengan menggunakan protokorm anggrek Vanda limbata  Blume x Vanda tricolor Lindl. yang berumur 4 minggu (fase 2) yang ditanam pada medium perlakuan. Medium perlakuan yang digunakan adalah medium POC yakni Fertile, Fish Emultion dan Nasa dengan beragam konsentrasi (1; 1; 2; 2,5; 3; 3,5 ml/L) yang ditambahkan air kelapa 150 ml/L, sedangkan medium VW sebagai kontrol positif dan medium agar sebagai kontrol negatif. Pengamatan pada medium perlakuan dilakukan selama 2 bulan. Pengamatan dilakukan untuk mengukur parameter morfologis (panjang daun, jumlah daun, panjang akar, dan jumlah akar) serta jumlah tunas yang dihasilkan hingga pengamatan minggu ke-8. Setelah 2 bulan, tanaman kemudian disubkultur ke medium VW yang ditambahkan air kelapa dan ekstrak pisang. Data kuantitatif yang diperoleh kemudian dianalisis dengan Analysis of Variance (ANOVA) untuk mengetahui pengaruh pupuk organik cair terhadap parameter yang diukur kemudian jika terdapat perbedaan nyata dilanjutkan dengan Duncan’s Multiple Range Test (DMRT) pada taraf uji 5 %. Hasil penelitian menunjukkan bahwa pengaruh medium POC terhadap pertumbuhan dan perkembangan embrio anggrek menunjukkan respon yang berbeda-beda pada setiap fase pertumbuhan. Pada protokorm anggrek Vanda limbata  Blume x Vanda tricolor Lindl. berumur 4 MSP, POC Fertile 1,5 memberikan hasil yang berbeda nyata dibandingkan dengan medium VW pada parameter jumlah daun dan jumlah tunas dengan nilai 4,67 dan 6,00.Kata kunci: Pupuk Organik Cair, Perkecambahan In Vitro, Embrio, dan Anggrek

Abstract

Stelechocarpus burahol is one of the medicinal plants that contains flavonoids. The study was carried out to know flavonoid production of cultures in vitro S. burahol from mesocarp explants. Mesocarp explants were cultured on MS medium containing different combination and concentration of plant growth regulators i.e. picloram (5, 7.5 and 10 mg/L) and 2, 4-D (10, 15 and 20 mg/L) under dark condition. Induction of callus formation started on the 20.29th to the 29.86th days. Medium supplemented with Picloram and dark state proved to be the best condition for optimum callus induction from mesocarp explants of S. burahol. Callus grown on medium with the addition of 7.5 mg/l Picloram produces the highest flavonoid. The maximum production of the secondary metabolite was obtained from 8 weeks old callus. However, by the time of callus ageing, its output has declined. It could be concluded that callus cultures from mesocarp S. burahol can be used for flavonoid production.How to CiteHabibah, N.

Abstract

This experiment was aimed to evaluate the copper accumulation using callus culture of Datura metel L. The culture was established from leaves onto MS contained NAA 2.5 mg/L and Kinetin 0.5 mg/L as the control. The exposure of the culture was carried out by 2 copper compounds as treatment, i.e. CuCl2.2H2O and Na2CuEDTA at level concentration 0.; 0.1; 5; 10; 15; and 20 M. The growth pattern of callus in control showed increasing growth rate in 36 days, whereas exponential stage was reached at 12-20th doi*. Whilst, after 10 doi, the treatment showed constant growth pattern. The absorption rate of the culture was increased by the addition of the CuCl2.2H2O at 5 15 M of level concentration but declined at 20M. The maximum rate of accumulation of Cu (0,1519 mg g-1) was obtained at 15 M. Instead, the addition of Na2CuEDTA at 5 20M of level concentration showed the significant increment while the maximum accumulation was obtained at 20M (0,1420 mg g-1). The existence of chelator in copper compound reduced the rate of toxicity while all tolerance index values were between 66,24 and 97,28 %.The results suggested the role of callus of D. metel as that fairly absorbed and accumulated Cu2+. Exposure with CuCl2.2H2O indicated higher accumulation than Na2CuEDTA.How to CiteNurchayati, Y., Santosa, S., Nugroho, L. H., & Indrianto, A. (2016).

Abstract

Vanda tricolor  Lindl. var. suavis  is an Indonesian wild orchid which is now extremely rare in nature due to its habitat  destruction.  Development  of  an  appropriate  method  for  improving   Vanda  orchid  through  genetic modification could be valuable for horticulture and, indirectly, also for conservation. In this research, a method of  Agrobacterium-mediated transformation of two  Vanda  tricolor  obtained  from  Salak Mount, West Java and merapi Mount, Yogyakarta in Indonesia protocorms was improved using acetosyringone (AS). Concentrations of 0 and 25 ppm AS were used in transformation of pG35S binary vector containing kanamycin resistance gene into V.  tricolor  protocorms.  The  result  showed  that  25  ppm  AS  was  required  on  innoculation  with Agrobacterium  solution, without AS on cocultivation. Five week s after  treatment  on the 300  ppm kanamicyncontaining medium, green protocorms were obtained, that  was  11.01% for  V.  tricolor  from Salak Mount with pre-culture treatment prior to innoculation, 9.39% for  V.  tricolor  from Merapi  Mount with pre-culture treatment prior to  innoculation,  and  1.37%  for  V.  tricolor  from  Merapi  Mount  without  pre-culture  treatment  prior  to innoculation. The  best  condition  to  set  high  efficiency  of  transformation  is  pre -culture  protocorms  prior inoculation, soaking protocorm on 25  ppm  AS for 30 minutes, then cocultivate its on AS-free  callus induction medium Key words: Vanda tricolor, Agrobacterium, orchid protocorms, acetosyringone
