Auxin Concentration

In vitro propagation system has been developed for an important ornamental and medicinal plant, Muscari armeniacum Leichtil. ex Bak. A range of a cytokinin and auxin concentration has been investigated for axillary bulblet proliferation, and direct and indirect adventitious bulblet regeneration from the explants whole bulb, one fourth part of bulb, bulb-scale of ex vitro (field grown mature bulb), and only leaf-sheath explants of in vitro grown bulblet. Axillary bulblet regeneration occurred on MS containing 2.0 - 8.0 ?M BAP or Kn. Direct adventitious bulblets were induced successfully on MS basal medium supplemented with various concentrations of BAP or Kn (1.0 - 4.0 ?M) in combi-nation of either NAA, IBA, or 2,4-D (0.5 - 4.0 ?M). The maximum frequency of adventitious bulblets regeneration occurred from both bulb-scale and leaf-sheath explants on MS with 4.0 ?M BAP and 2.0 ?M NAA, IBA, or 2,4-D. The highest frequency (95.5%) of indirect adventitious bulblets was obtained from in vitro grown leaf-sheathderived callus on MS containing 4.0 ?M BAP with 1.0 ?M 2,4-D whereas, highest number (80.2) and average length (55.5 cm) of bulblets were obtained on MS supplemented with 4.0 ?M BAP and 1.0 ?M NAA. In vitro grown bullets was rooted successfully on MS with 0.5 - 4.0 ?M of IBA, NAA, or IAA. The rooted bulblets were transferred to garden soil and successfully established under ex vitro environment.

Callus culture was initiated from leaf discs on MS supplemented with BAP, NAA and Kn. The highest frequency (95%) of organogenic callus induction was observed in MS containing BAP at 3.0 mg/l and NAA at 0.3 mg/l. Development of adventitious shoots occurred when the calli were subcultured on MS supplemented with BAP alone at the rate of 3.0 mg/l (80%) and BAP with NAA at the rate of 3.0 and 0.3 mg/l, respectively (95%) and BAP with Kn at the rate of 3.0 and 0.3 mg/l, respectively (70%). The root initiation and the rate of growth were higher in the basal medium containing BAP at 3.0 and 2.5 mg/l. The plantlets were establish successfully in the hardening medium composed by coir pith and soil (1 : 1).Key words: Acmella calva, Leaf derived callus, Nilgiris, India  Plant Tissue Cult. & Biotech. 17(2): 109-114, 2007 DOI: 10.3329/ptcb.v17i2.2566

Nodal Culture

Nodal explants of 12 accessions from four species of yam (Dioscorea spp.) were cultured for six weeks on MS to evaluate the influence of IAA, Kn, NAA and BAP on the production of leaves and microtubers. Four Dioscorea polystachya Turcz., three each of D. bulbifera L. and D. sansibarensis Pax. and two D. japonica Thunb. accessions were used. Five and 10 mg/l of Kn along with IAA and sucrose, and 0.2 and 0.5 mg/l of NAA, sucrose and with or without BAP were used in four treatments. The accessions Yam 23 and Yam 25 of D. sansibarensis failed to initiate any leaf under four treatments. The remaining accessions produced 0.11 to 1.76 leaves per explant. The medium containing IAA with higher concentration of Kn (10 mg/l) and 3% sucrose was found to be best for in vitro production of leaf (0.71/explant) and the most productive species was D. japonica (1.36), followed by D. polystachya (1.19/explant). At the same culture period, Yam 16 of D. bulbifera failed to initiate any microtuber at IAA with Kn, and NAA with or without BAP. The remaining accessions produced 0.09 to 1.15 microtubers per explant. Lower concentration of Kn (5 mg/l) with IAA and sucrose was favourable for producing microtubers (0.61/explant on an average), the best species being D. sansibarensis (1.27) followed by D. japonica (0.59/ explant). Finally, the presence of BAP adversely affected the production of microtuber among Dioscorea species. Key words: Dioscorea spp., Microtuber, Nodal culture, Propagation D.O.I. 10.3329/ptcb.v18i1.3260 Plant Tissue Cult. & Biotech. 18(1): 25-35, 2008 (June)

An experiment was carried out in Plant Tissue Culture Laboratory, Department of Crop Botany, Bangladesh Agricultural University, Mymensingh to investigate the effect of banana extract on micropropagation of  <i>Dendrobium</i> sp. var. Sonia orchid through PLBs. The experiment was conducted during July 2012 to October 2013. Half-Murashige and Skoog (1/2MS) medium were used as basal medium and the medium was supplemented with banana extract at 12.5, 25, 50, 100, and 200 ml L-1 with a control, where no banana extract was supplemented. The cultures were done in 100 ml conical flasks and maintain at 25°C with 30µ mol m-2 S-1 lighting provided by florescent tubes for 16 hours per day. Banana extract showed significant effect on growth and development of PLBs. Among the treatments, 100 ml L-1 banana extract enhanced new PLBs regeneration from explanted PLBs and growth and development of PLBs. Present research indicated that nutrient requirement for PLBs multiplication and plantlets growth of  Dendrobium orchid is quantitatively different in vitro. Finally, 100 ml L-1 and 25 ml L-1 of banana extract may be recommended as supplement into 1/2MS medium for PLBs multiplication and plantlet regeneration, respectively in vitro.The Agriculturists 2015; 13(1) 101-108

Culture Protocol

Abstract Disinfection of plant material is the most important step of the tissue culture protocol. In this process, an attempt is made to eliminate microbial contaminants from the surface and interior of plant material, thus giving the explant a fighting chance at survival in vitro. Initial cultures of Anthurium species and cultivars, which are usually established from ex vitro material grown in a greenhouse, pots or in the field, easily contaminate the in vitro milieu. This review highlights the differences in disinfection protocols that exist for different species or cultivars of Anthurium. The protocol needs to be adjusted based on the material used: spadices, spathes, seeds, leaves, or roots. Regrettably, most of the currently published protocols, derived from a literature that spans over 100 published papers, have numerous weaknesses and flaws in the information provided pertaining to disinfection and infection levels. Advice for future Anthurium researchers should thus be followed cautiously.

Biodiversity is declining with the loss of natural forests across the world. Plant tissue culture is an important biotechnological tool to raise large number of plant species in short spa of time. However, commercial tissue culture laboratories are working on raising plantlets important for human consumption only; which mainly include fruit crops, ornamental plants, timber-yielding forest trees and medicinal plants. There is an urgent need of raising all the different plant species rapidly through tissue culture. Through cultivation of these high yielding and disease-free crops in the forests for consumption of all other species of fauna; conservation of biodiversity can be achieved. However, as tissue culture plantlets are costlier than conventionally raised plants, despite of its advantages its utility is limited. To reduce cost of an important fruit crop, banana during its in vitro regeneration, cost-effective alternatives are proposed.
