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.

Effects of different concentrations of 2-ip and IBA in WPM basal medium for Blomidon blueberry in vitro propagation and four different rooting agents at the early stage after transplantation showed that 15 mg/l of 2-ip is the best concentration to induce shoots. For optimum in vitro root formation 10 µM IBA was found to be best and four rooting agents for seedling transplantation according to their effects were No.2>, No.4>, No.3 >, water > and No. 1. Key words: Blomidon, Tissue culture, In vitro regeneration, Rooting agent D.O.I. 10.3329/ptcb.v18i2.3650 Plant Tissue Cult. & Biotech. 18(1): 187-195, 2008 (December)

Tissue culture is a useful means to clonally propagate new ornamental plant selections, particularly when plant material is limited and/or conventional propagation methods are ineffective. An efficient in vitro multiplication protocol was established to propagate a new goatsbeard hybrid (Aruncus dioicus, × A. aethusifolia). The hybrid is of interest because it exhibits a dwarf habit, delicate white flower panicles and fern-like leaves, yet is tolerant to heat and humidity. Experiments were conducted to evaluate explant type (nodes, stems, leaves, and floral parts), disinfestation procedures, and media formulations including varying concentrations of 6-benzylaminopurine (BAP) and naphthalene acetic acid (NAA). Rapid plant regeneration was obtained with a shoot organogenesis system using a half strength Murashige and Skoog medium supplemented with 4.4 μmol BAP, 0.54 μmol NAA, 30 g·L-1 sucrose, and 3.0 g·L-1 GelGro. Studies compared the performance and yield of plants rooted using different in vitro and ex vitro methods. Ex vitro rooting of shoots during greenhouse acclimatization under mist was most effective. Regenerated plants exhibited uniform and rapid growth, and performed well in greenhouse and field evaluations.

Tissue culture of plants has many applications, from producing genetically identical horticultural varieties, to production of secondary metabolites, to virus indexing, and most relevantly, developing novel traits by genetic transformation. Using Agrobacterium-mediated transformation on somatic embryos, blight-resistant American chestnuts [Castanea dentata (Marsh.) Borkh.] have been developed as shoot cultures in plant tissue culture. Rooting tissue-cultured shoots and acclimatizing the rooted plantlets are key steps in tree production. In this study, in vitro and ex vitro rooting methods were compared. The ex vitro method resulted in a lower initial rooting percentage but an overall higher survival percentage, resulting in higher potted plant production. The higher survival was likely due to partial acclimatization taking place before the plantlets were transplanted into potting mix. After 8 weeks, plantlets rooted via the ex vitro method were taller, and had more, and larger, leaves than the in vitro-rooted plantlets. These trees are currently in high demand for inoculation studies for federal regulatory review and eventually for restoration of this keystone species to its native habitat.

An efficient mass propagation method for Feronia limonia was developed from excised shoot tips and nodal explants of in vitro grown seedlings. Explants were cultured on MS medium with different conc. of NAA, Kn, IAA and BAP singly or in combinations. Highest number of micro shoots and better plant growth were obtained from these two explants on MS medium supplemented with 0.2 mg/l BAP alone. The regenerated shoots were successfully rooted on MS medium supplemented with 0.5 mg/l NAA. The in vitro raised plantlets were successfully established in soil following the formation of roots with 100% survivability under ex vitro condition.

In Africa and Asia, members of the genus Brachystelma are well-known for their diverse uses, especially their medicinal and nutritional values. However, the use of many Brachystelma species as a valuable resource is generally accompanied by the concern of over-exploitation attributed to their slow growth and general small size. The aim of the current study was to establish efficient micropropagation protocols for three Brachystelma species, namely Brachystelma ngomense (endangered), Brachystelma pulchellum (vulnerable) and Brachystelma pygmaeum (least concern), as a means of ensuring their conservation and survival. This was achieved using nodal segments (~10 mm in length) as the source of explants in the presence of different concentrations of three cytokinins (CK) namely N6-benzyladenine (BA), isopentenyladenine (iP) and meta-topolin riboside (mTR), over a period of 6 weeks. The highest (25 µM) concentration of cytokinin treatments typically resulted in significantly higher shoot proliferation. However, each species differed in its response to specific CK: the optimal concentrations were 25 µM mTR, 25 µM iP and 25 µM BA for Brachystelma ngomense, Brachystelma pulchellum and Brachystelma pygmaeum, respectively. During the in vitro propagation, both Brachystelma ngomense and Brachystelma pygmaeum rooted poorly while regenerated Brachystelma pulchellum generally lacked roots regardless of the CK treatments. Following pulsing (dipping) treatment of in vitro-regenerated shoots with indole-3-butyric acid (IBA), acclimatization of all three Brachystelma species remained extremely limited due to poor rooting ex vitro. To the best of our knowledge, the current protocols provide the first successful report for these Brachystelma species. However, further research remains essential to enhance the efficiency of the devised protocol.
