The plant species, Anaphalis elliptica DC. (Asteraceae) is a medicinal herb endemic to high hills of Nilgiri Biosphere Reserve, the Western Ghats. The in vitro propagation study of this species by using leaf, node and shoot tip explants, revealed the following results: Among the three explants used, leaf and node responded well for callus and shoot initiations respectively. The leaf explant produced callus effectively (91%) in the MS medium supplemented with BAP and NAA at 2.5 and 0.3 mg/l respectively, whereas the nodal explant produced higher amount of shoots (92%) in the basal medium containing the growth regulator, BAP alone at 3.0 mg/l. The leaf derived callus produced higher (80%) shoot initials and shoot multiplication in the MS medium augmented with BAP and NAA at 3.0 and 0.5mg/l respectively. Similarly, the in vitro nodal derived shoots produced higher shoot multiplication (87%) in MS medium supplemented with BAP at 3.0mg/l. The regenerated shoots of both the explants were successfully rooted on MS medium supplemented with IBA and NAA at 1.0mg/l each. After sequential hardening the leaf callus derived plantlets registered higher survivability rate (80%) in the hardening medium containing decomposed coir waste, perlite and compost in the ratio of 1:1:1 by volume. Similarly, the survivability rate of nodal derived plantlets was higher (84%) in the hardening medium composed by vermicompost and soil in the ratio of 1:1 by volume.

Shoot tip explants of Algerian Ivy Heder a canariensis were cultured on MS basal medium supplemented with a combination of salt strength and NAA and IBA. More roots per explant developed on full salt strength medium combined with NAA. The most roots per explant were obtained with a combination of IBA and 1/4 MS salt. There was an inverse relationship between an increase in IBA or NAA concentration and root length and number. Shoots proliferated better on full MS salt combined with NAA and IBA. The highest level of NAA (40 uM) and 0.1 uM TDZ produced the most shoots and roots, the longest roots, the highest rooting percentage, the largest plants with the most leaves and the best callus quality per explant. The leaves from in vitro were cultured on MS medium with varying levels of Thidiazuron (TDZ) and NAA in the presence of light produced the highest number of roots.

We can see Orchids come in a wide variety of shapes, sizes, colours, and textures far beyond the human mind’s imagination. They emerge from seeds in nature, but in the absence of suitable hosts, they do not germinate in sufficient numbers. This problem was solved by using the tissue culture technique for its germination. One of the successful method used for mass propogation of orchid plantlets is in vitro techniques. Therefore, an initial analysis was conducted in order to establish an appropriate procedure for mass multiplication of Arundina graminifolia. MS (Murashige and Skoog) medium was found to be suitable for the asymbiotic seed germination of Arundina graminifolia. Direct protocorm like bodies were induced by using combinations and individual supplement of MS medium with IAA (Indole-3-acetic acid), IBA (Indole-3- butyric acid), BAP (6-Benzylaminopurine) and KIN (Kinetin). Hormone-free MS basal medium was found suitable for the conversion of PLBs (protocorm-like bodies) into complete plantlets

An investigation was conducted on Fast Protocol for High Frequency in vitro cloning of Banana (Musa acuminata) cv. Grande Naine at the Biotechnology-cum-Tissue Culture Center, OUAT, Bhubaneswar, during the year 2012. This has helped to determine the best media compositions for shoot multiplication and rooting of cv. Grande Naine, so as to get optimum results with a minimized cost of production. MS medium supplemented with 4.0 mg/1 Benzylaminopurine (BAP) and 2.0 mg/1 Kinetin gave the highest number of shoot/explants (11.33) in 30 days. However, MS medium when supplemented with 6.0 mg/1 BAP produced a maximum number of leaves (19.07) with a maximum height 2.73 cm. Among various concentrations of indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) and naphthaleneacetic acid (NAA) for rooting. Half MS medium supplemented with 1.0 mg/1 IBA was found to be ideal for early rooting and producing more number of roots in 21 days. However, MS basal medium was found to be the best treatment to support the formation of long roots. This protocol can be very useful to the future research worker and as well as entrepreneurs for mass production of banana (Musa acuminata) cv. Grande Naine.

Shoot explants from actively growing, greenhouse-maintained plants of Baptisia `Purple Smoke' were cultured in vitro for shoot initiation on Murashige and Skoog (MS) basal medium containing vitamins and supplemented with 30 g·L–1 sucrose, 8.87 μm BA, and 4.14 μm K-IBA. All subsequent media were supplemented with 2.47 mm NaH2PO4 to enhance shoot growth. Single-node explants were subcultured for shoot multiplication on MS medium with either no plant growth regulator or with 2.22, 4.44, 8.87, 17.74, or 35.48 mm BA in combination with 0.0 or 4.14 μm K-IBA. Explants produced a maximum of 4.1 shoots on the medium with 2.22 μm BA. Shoots rooted on all concentrations of K-IBA (2.07, 4.14, 10.36, or 20.72 μm) and K-NAA (2.23, 4.46, 11.15, or 22.29 μm) tested. Maximum rooting was 100% on MS medium with 11.15 μm K-NAA; however, this treatment induced copious stem callusing. Rooted shoots were greenhouse-acclimatized for 2.5 weeks. Overall survival was 86%. For optimal rooting and subsequent acclimatization, treatment with 2.23 μm K-NAA is recommended; this resulted in 83% rooting and 87% acclimatization. Chemical names used: N6 benzyladenine (BA); potassium salt of indole-3-butyric acid (K-IBA); potassium salt of 1-naphthalene acetic acid (K-NAA).

Background: Curcuma caesia Roxb. (Zingiberaceae) is a rare, critically endangered medicinal plant of Northeast India. The rhizome of the plant is famous for its significant medicinal properties. Methods: Various concentrations of plant growth regulators in Murashige and Skoog (MS) medium were tried in the study using rhizome bud as explant for development of an efficient cost effective protocol for in vitro mass multiplication and microrhizome induction of Curcuma caesia. Result: Shoot multiplication and plant generation was achieved from freshly sprouted shoots of Curcuma caesia on Murashige and Skoog’s medium supplemented with different phytohormones. The best response for shoot multiplication (23.80±0.51shoots/explant) was obtained within 8 weeks in MS medium supplemented with BAP (1.0 mgl-1) and 2,4-D (0.25 mgl-1). Microrhizomes were induced at the base of the in vitro derived shoots upon transferred to medium containing various combinations and concentrations of sucrose and BAP and grown under varying photoperiod. Half strength of MS basal medium containing BAP (1.0 mg/l) and 9% sucrose was found to be optimum for induction of large sized microrhizome within 45 days of incubation under 16 hrs of photoperiod.

Objective: The objective of this study was to establish the method of propagation of Oryganum vulgare and Lippia graveolens employing a plant tissue culture technique that decreased the phenolization percentages and increased the multiplication coefficients. Design/ methodology/ approach: The in vitro germination percentage was evaluated in both MS and MS medium + activated carbon. Microcuttings (small shoots) of both species were established in base medium added with different antioxidant agents to decrease the phenolization of explants; the treatments were arranged in a completely randomized block  design. For the propagation phase, a completely randomized factorial design was used, where the auxin/cytokinin phytoregulators, type of explants (axillary buds and leaves), and the species (Lippia graveolens and Oryganum vulgare)  were considered as factors. Results: maximum germination (63.3% ±12.5) was obtained on day 15 ​​in both culture media for L. graveolens and O. vulgare. The use of antioxidant agents mainly activated carbon, increased the in vitro establishment and activation of vegetative buds in both species by up to 90%. There were significant differences in the variables evaluated regarding the treatments, the explant, and the species in the multiplication phase. The combination 1.0/ 0.5 mg L-1 BA/AIB induces callus formation for both species. When used as leaf explants, callus formation was potentiated. Study Limitations / Implications: The results presented are advances from a long-term experiment. Findings/conclusions: The germination of L. graveolens seeds can be achieved in MS medium after 15 days. Microcuttings of both L. graveolens and O. vulgare were successfully established in MS basal medium enriched with 1 g L-1 charcoal that showed low oxidation percentages and induced up to 90% the production of shoots in the explants. The mixture of 1.0/0.5 mg L-1 BA/AIB induces callus formation for both species; when this medium is in contact with leaves as an explant, its formation is potentiated, achieving diameters up to 15 mm. In order to achieve the induction of shoots and roots, buds should be established in MS medium enriched with 0.5 mg L-1 IBA for both species; this mixture encreased the multiplication coefficients

Rapid shoot multiplication of Nyctanthes arbortristis was achieved from axillary meristems on Murashige and Skoog (MS) basal medium supplemented with 1.0−1.5 mg/l 6-benzyladenine (BA), 50 mg/l adenine sulfate (Ads) and 3% (m/v) sucrose. Inclusion of indole-3-acetic acid (IAA) in the culture medium along with BA + Ads promoted a higher rate of shoot multiplication. Maximum mean number of microshoots per explant (6.65) was achieved on the MS medium supplemented with 1.5 mg/l BA, 50 mg/l Ads and 0.1 mg/l IAA after 4 weeks of culture. The elongated shoots rooted within 13 to 14 days on ½ strength MS medium supplemented either with indole-3-butyric acid (IBA), IAA or naphtylacetic acid (NAA) with 2% sucrose. Maximum percentage of rooting was obtained on medium having 0.25 mg/l IBA, 0.1 mg/l IAA and 2% sucrose. About 70% of rooted plantlets survived in the greenhouse. The in vitro raised plants were grown normally in the soil condition. This result will facilitate the conservation and propagation of the important medicinal plant.

Surface disinfested nodal and shoot-tip sections of chinkapin oak (Quercus muehlenbergii Engelm.), obtained from adult or juvenile source, when cultured on WFM supplemented with BA or kinetin (1.0 -5.0 mg l-1) produced greater number of axillary shoots per explant and shoot lengths than MS medium. Nodal and shoot-tip explants cultured in WPM containing cytokinins, BA or kinetin (0.1 - 5.0 mg l“) resulted in greater number of axillary shoots than media containing auxins, 2,4-D or NAA (1.0 - 5.0 mg l-1). In vitro grown shoot explants cultured in WFM shoot multiplication medium containing thidiazuron did not produce axillary shoots. Microshoots when cultured in WFM plus NAA or IBA (0.1 -2.0 mg l-1), or subjected to IBA (0.5 mg l-1) pulse treatment (0, 5, 10 or 15 min.) did not root.
