Cinchona Ledgeriana

SummaryCinchona ledgeriana (Ledger) and C. succirubra (Succi) were industrial commodities which their barks of the trunk  contain alkaloid   used as raw materials in pharmaceutical, food, drug and beverages and chemical industries. The problem  faced in conventional plant propagation are. incompatibilities, high numbers of death caused by transportation, limited numbers and time consume in  plant materials  production. These problems may be  overcome by axillary buds multiplication.  The aim of the experiment were to find out propagation technology of Ledger and Succi by  tissue culture technique.  Experiments were conducted in three consecutive steps, viz the effect of (i) BAP on multiplication and growth of axillary’s bud of Ledger and Succi in vitro culture, (ii) IBA on root initiation and growth, (iii)  growth medium on the growth of plantlets in  acclimatization.The design of the experiments were Complete Randomized Design with 15 (i & ii) and four (iii) replications. The treatments were (i) 0,1,2,3,4, dan 5 mg/L BAP, (ii) 0.0; 0.5; 1.0; 1.5; 2.0; dan 2.5 mg/L IBA, and (iii) mixture of soil and rice husk charcoal (1:1), mixture of soil and compost (1:1),  mixture of soil, rice husk charcoal, and  compost  (1:1:1).  Parameters measured in the experiments were (i) the initiation of buds multiplication rate twice at axillary buds at subculture.  (ii) initiation  and  roots vigor. (iii) numbers of survived  plants and plants vigor. The explant source used derived from two-month old axillary buds cultured in Murashige and Skoog (MS) medium without growth regulator. Results of the experiment showed  that the best shoot multiplication of Ledger  and Succi  was obtained from the application of 3 mg/L BAP, with buds multipli-cation rate 7 buds/explant/month for Ledger, and 3-4 buds/explants/month for succi. The best root initation and root growth were found from the application of 2 mg/L IBA. The highest percentage of survived plantlets (100%) in acclimatization was obtained from mixture of soil and rice husk charcoal (1:1) medium.  Therefore it is  concluded that tissue culture technique could be used for planlet  mass propagation    of  elite C. Ledgeriana and C. Succirubra through axillary bud multiplication.Ringkasan Tanaman kina Cinchona ledgeriana (Ledger) dan C. succirubra (Succi)  merupakan tanaman industri yang mengandung alkaloid di dalam kulit batangnya dan berguna dalam bidang industri farmasi, makanan, minuman dan kimia. Kendala yang dihadapi dalam perbanyakan tanaman kina secara konvensional dengan sistem sambung  adalah inkompatibilitas,    kematian akibat pengangkutan cukup tinggi, jumlah bahan tanam yang diproduksi sangat terbatas dan waktu penyediaan yang cukup lama. Masalah tersebut dapat diatasi dengan menggunakan teknik kultur jaringan. Penelitian ini bertujuan untuk men-dapatkan teknologi perbanyakan tanaman kina Ledger dan Succi dengan teknik kultur jaringan. Penelitian terdiri atas (i) pengaruh BAP terhadap inisiasi dan penggandaan  tunas aksilar, (ii) pengaruh IBA terhadap inisiasi serta pertum-buhan akar planlet,   dan (iii) pengaruh beberapa medium terhadap pertumbuhan planlet dalam aklimatisasi. Percobaan menggunakan Rancangan Acak Lengkap, masing-masing diulang 15 (i & ii)  dan (iii) empat kali. Peubah yang diukur untuk percobaan (i) adalah waktu inisiasi tunas dan laju penggandaan tunas aksiler pada dua  kali  subkulur. (ii)  Waktu  inisiasi  dan vigor akar. (iii) Jumlah tanaman yang bertahan hidup setelah aklimatisasi, serta vigor tanaman. Sumber eksplan yang digunakan adalah tunas aksilar dari kecambah terpilih berumur dua bulan yang dikulturkan dalam medium Murashige dan Skoog tanpa zat pengatur tumbuh. Perlakuan untuk percobaan (i) adalah 0,0; 1,0; 2,0; 3,0; 4,0 dan  5,0 mg/L BAP, (ii) adalah 0,0; 0,5; 1,0; 1,5; 2,0; dan 2,5 mg/L IBA, sedang (iii) adalah medium tanam tanah, tanah : arang sekam (1:1),  tanah : kompos (1:1), tanah : arang sekam : kompos (1:1:1). Hasil yang diperoleh menunjukkan bahwa konsentrasi BAP terbaik untuk inisiasi dan penggandaan tunas tanaman kina Ledger dan Succi adalah 3 mg/L BAP, dengan laju penggandaan tujuh tunas/eksplan/bulan untuk Ledger dan 3-4 tunas/eksplan/bulan untuk Succi. Sedang untuk perakaran diperoleh dari medium MS dengan penambahan 2 mg/L IBA. Persentase tertinggi planlet (100%) yang mampu bertahan hidup pada aklimatisasi diperoleh dari medium campuran tanah : arang sekam (1:1). Berdasarkan hasil tersebut di atas dapat disimpulkan bahwa perbanyakan tanaman kina secara in vitro untuk menghasilkan bibit bermutu dapat dilakukan melalui teknik penggandaan tunas aksiler

Banana Wilt

Blood Disease Bacterium (BDB) and Fusarium oxysporum f.sp. cubense (FOC) is a couple wilt pathogen  of  banana.  These pathogens are the most important constraint in cultivation of banana in Indonesia.  In the integrated control strategy of the disease, the use of healthy seedlings produced from tissue culture technique is recommended.  The seedling produced by tissue culture technique however leads to lower vigor and susceptibility to the disease due to the aseptic work in vitro causing the beneficial bacterial endophytic to be eliminated. Therefore, the utility of the beneficial endophytic bacteria should be studied for recovering the vigor and resistance of the seedling.     Three isolates of endophytic Bacillus (B04, B05, B10) have been effective as growth promoter of microplantlet and antagonist of BDB and FOC in vitro.   Here then, this article reports the study results of the vigor of the plantlet (treated microplantlet by filtrate or cell suspension of the Bacillus) after 3 months in acclimatization. The results were similar to the previous results on microplantlet in vitro, that Bacillus isolates B04, B05, and B10 were capable of promoting the growth and inducing the resistance to wilt pathogens on banana plantlets.  The treatments with bacterial cell inoculums were more effective than those bacterial filtrate. Isolate B10 was most potential followed by B05 and B04 respectively.

ABSTRACT A review is given of previous in vitro investigations on oestrogen metabolism. In the present investigation use has been made of the tissue culture technique, whereby possible blood or serum effects on oestrogen transformations could be excluded. The conversion products were characterized by chemical methods. In the presence of bovine kidney cells grown on a medium of known composition, the following conversions were recorded: Oestrone to oestradiol-17β, oestradiol-17β to oestrone, oestradiol-17α to oestrone. Control incubations of the hormones with medium only showed that the transformations must be due to the presence of the living cells. The rate of conversion to oestrone was markedly higher for oestradiol-17β than for oestradiol-17α. As previous in vivo experiments have shown oestradiol-17α to be an important end product in the bovine, following injections of both oestrone and oestradiol-17β, the free interconvertibility of oestrone and oestradiol-17β demonstrated in the present investigation becomes significant. The findings are discussed in relation to recent observations on hormoneenzyme interrelations.
