The present investigation aimed to standardize efficient plant regeneration protocol through in vitro culture by using nodal segment for mass multiplication of Lawsonia inermis an economically important medicinal plant species. Mass multiplication of shoots induced on Murashige and Skoog (MS) medium supplemented with different growth regulators like auxins and cytokinins separately and in different combinations. The medium fortified with 6-Benzylaminopurine ( BAP) 1.0 mg/l + kinetin (KN) 1.5mg/l  explained best compared to all other combinations. In vitro raised plantlets were excised and transferred in half strength MS  medium supplemented with different growth regulators like Indole Butyric acid ( IBA)  and naphthalene acetic acid (NAA ) (0.5-3.0 mg/l) in an experiment that gave rise to rooting. The half strength of MS medium additive with IBA in separate and in different combinations with NAA concentrations (0.5-3.0 mg/l) supported root development. The best response of rooting was obtained on half MS medium fortified with 1.0 mg/l IBA. The regenerated plantlets were successfully transplanted to pots. Regenerants were transferred to the field conditions and recorded the survival rate.. Among all the carbon sources and gelling agents used, sucrose (3%) in combination with 0.8 per cent agar-agar has proved significantly better. Multiple shoots formation with longer shoots were achieved on medium with 1.0mg/l BAP and 1.5mg/l Kn. Thus, it is possible to develop a large number of plants of L. inermis through shoot bud regeneration which can cater for the need of pharmaceutical as well as other industries.

AbstractHybanthus enneaspermusis a rare medicinal plant. We defined a protocol for micropropagation,ex vitrorooting of cloned shoots and their acclimatization. Surface-sterilized nodal segments were cultured on Murashige and Skoog (MS) medium with different concentrations of 6-benzylaminopurine (BAP) and kinetin (Kin). Medium supplemented with 1.5 mg L−1BAP was found optimum for shoot induction from the explants and 6.4±0.69 shoots were regenerated from each node with 97% response. Shoots were further proliferated maximally (228±10.3 shoots per culture bottle with 7.5±0.43 cm length) on MS medium augmented with 1.0 mg L−1each of BAP and Kin within 4–5 weeks. The shoots were rootedin vitroon half strength MS medium containing 2.0 mg L−1indole-3 butyric acid (IBA). The cloned shoots were pulse-treated with 300 mg L–1 of IBA and cultured on soilrite® in a greenhouse. About 96% of the IBA-pulsed shoots rootedex vitroin soilrite®, each shoot producing 12.5±0.54 roots with 5.1±0.62 cm length. Theex vitrorooted plantlets showed a better rate of survival (92%) in a field study thanin vitrorooted plantlets (86%). A comparative foliar micromorphological study ofH. enneaspermuswas conducted to understand the micromorphological changes during plant developmental processes fromin vitrotoin vivoconditions in terms of variations in stomata, vein structures and spacing, and trichomes. This is the first report onex vitrorooting inH. enneaspermusand the protocol can be exploited for conservation and large-scale propagation of this rare and medicinally important plant.

Context: Mimosa pudica L. is an important medicinal plant belonging to the family- Mimosaceae has becoming a rare species in Bangladesh. The application of artificial seed technology using encapsulated shoot tips and nodal segments may contribute to the protection of rare and threatened medicinal plant like Mimosa pudica L.Objective: Synthetic seed technology has been developed for Mimosa pudica L. in order to develop an alternative protocol on propagation and conservation.Materials and Methods: For this purpose shoot tip and nodal segments obtained from in vitro grown plants were encapsulated with sodium alginate solution followed by subsequent immersion in CaCl2 solution. Different concentrations and combinations of growth regulators were used and explants were treated in alginate bead to investigate the hormonal effect on artificial seed germination. These encapsulated seeds were cultured either on MS medium with hormone (same growth regulators containing alginate beads) or MS0 (without hormone).Results: Highest shoot regeneration frequency (100%) were recorded when alginate beads were infused by MS medium supplemented with 2.0 mg/l BAP + 0.2 mg/l NAA and cultured in MS medium containing same growth regulators. When synthetic seed containing 2.0 mg/l BAP+0.2 mg/l NAA and cultured on MS0 medium, 54% explants produced multifarious root with shoot in both cases. Under different storage period encapsulated seed retained germination capacity even after preserving for 60 days at 4°C.Conclusion: For artificial seed production a suitable protocol established under this study for Mimosa pudica L. that provides an alternative method for micropropagation and its conservation. For long term storage of Mimosa pudica in Bangladesh this protocol would provide promising avenues for the easy transference of propagules and its improvement.J. bio-sci. 22: 89-99, 2014

An efficient micropropagation protocol facilitates successful conservation and improvement of Nanorrhinum ramosissimum (Wall.) Betsche by biotechnological means. Shoot tip explants exhibited optimal organogenic response when inoculated on half-strength(1/2) Murashige and Skoog (MS) medium supplemented with kinetin (KN) and indole-3-acetic acid (IAA) (0.5 mg/L each). Shoot organogenesis was further enhanced when the multiplication medium was fortified with dextrose (1%) (2.6 shoots/explant; 7.9 cm shoot length). The regenerated shoots formed roots; however, the best rooting frequency (87%) was achieved on half-strength MS medium containing only IAA (0.5 mg/L). Four-week-old in vitro plantlets were acclimatized with 95% survival under greenhouse conditions. The regeneration protocol developed in this study can be utilized for germplasm conservation of this elite traditional medicinal plant.

Boerhaavia diffusa L., also known as santhi, or punarnava is an important medicinal plant, belonging to the family Nyctaginaceae. This species is said to be distributed throughout Malwa plateau in central India, as per ayurvedic literature, but due to extensive commercial exploitation, the species has become vulnerable. For callus induction, leaf explants were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations of 2,4- dichlorophenoxy acetic acid (2, 4-D 2.26 µM-9.04 µM) and N 6-benzyladenine (BA 1.11 µM-4.44 µM), either alone or in combinations. Calli formed within 10-12 days of culture, followed by shoots regeneration within 20-25 days. Direct organogenesis was achieved from nodal explants in MS media fortified with 2,4-D (2.26 µM-9.04 µM) along with BA (1.11 µM-4.44 µM) within 20 days. Multiple shooting was observed during subculture of in vitro regenerated shoots when 2,4-D was replaced with α-naphthalene acetic acid (NAA). Rooting was achieved in MS medium fortified with 2.85 µM IAA, within 7-10 days and also on half strength MS medium containing 2.85 µM Indole-3-acetic acid (IAA). For hardening, regenerated plants, with roots (3-4cm) were initially maintained on half-strength MS liquid medium (MS1/2) without growth regulators followed by quarter strength MS (MS1/4) liquid medium for 10 days. For acclimatization sterile mixture of soil, sand and manure (2:1:1) was used. Survival rate of regenerated plants was nearly 100%.

The aim of this study was to determine the possibility of micropropagation of the medicinal plant A. millefolium on half-strength MS medium and ex vitro rooting and acclimatization of the obtained microshoots in hydroculture in order to establish an efficient production method. Two explant types were used: basal and terminal cuttings, and better results were achieved when terminal cuttings were used. The development of shoots in the multiplication phase was successful with a regeneration percentage of 100%. Ex vitro rooting in a modified Hoagland nutrient solution was successful (83%), but the percentage of in vitro rooting on half-strength MS medium without hormones was higher (95%). However, bearing in mind that mass production of A. millefolium is more efficient when the phase of in vitro rooting is excluded, this method could be recommended for commercial propagation of this medicinal plant. It is necessary to conduct additional research in order to optimize the composition, EC and pH value of the hydroponic nutrient solution.

Anther of five varieties of Brassica species, namely BARI Shariaha-7, Tori-7, Agrani, Daulat and Safal were cultured in vitro to observe their regeneration potentiality. Different concentrations and combinations of growth regulators were supplemented in MS medium. The range of callus induction was 12.50-87.50 %. Maximum callus induction (75.00%) was observed on MS +4 mg/L 2, 4-D + 1.0 mg/L BAP. Among the genotypes, BARI Sharisha-7 showed the highest percentage of callus induction (60.42%). Among the treatments, highest percentage of shoot regeneration (75.00%) was observed on MS + 4 mg/L BAP + 1.0 mg/L NAA. BARI Sharisha-7 also showed the highest rate of plant regeneration (66.67%). Root induction was highest (75%) on half strength MS medium supplemented with 1.0 mg/L IBA and 0.5 mg/L NAA. The plantlets with sufficient roots thus obtained were transferred successfully to plastic pots and subsequently to the field. BARI Sharisha-7 and Tori-7 survived easily in the pots as well as in the field but Safal was very poor in survivability both in the pots and in the field.

Abstract The present study reports an efficient in vitro propagation system for Turnera ulmifolia using nodal segments as explants. Turnera ulmifolia (Passifloraceae) is an important garden plant with multipotent medicinal values. Effective shoot proliferation was achieved on agar gelled MS medium (Murashige and Skoog, 1962). The maximum number of shoots (8.3 ± 0.57) per initial explant was obtained on MS medium supplemented with 8.88 mM of 6-benzylaminopurine (BAP) and 0.54 mM of α-naphthalene acetic acid (NAA). The highest number of shoots (59.5 ± 2.10) proliferated on semi-solid MS medium (with agar) augmented with 2.22 mM of BAP and 2.32 mM of kinetin (Kin) along with 0.54 mM of NAA. Longer (4-5 cm) and healthy shoots were rooted (12.0 ± 0.10 roots per shoot) on half-strength MS medium fortified with 9.84 mM of indole-3 butyric acid (IBA). The in vitro regenerated plantlets were hardened in the greenhouse and transferred to the field. Significant developmental changes were observed in the foliar micromorphology of in vitro raised plantlets when these were transferred to the field. The stomatal index was gradually reduced (26.72 to 21.25) in the leaves from in vitro to field environments. But, vein-islets and veinlet terminations (13.4 and 7.6) were increased (39.7 and 18.4) respectively from in vitro to in vivo grown plants. Simple, unicellular, less frequent and underdeveloped trichomes were observed with the leaves of in vitro plants but fully developed trichomes recorded in the field transferred plants. The study could help in understanding the response and adaptation of tissue culture raised plantlets towards changed environmental conditions.
