Phyllanthus niruri (P. niruri) or Dukung Anak is a herbal plant in the Phyllanthaceae family that has been used traditionally to treat various ailments such as diabetes, jaundice, flu and cough. P. niruri contains numerous medicinal benefits such as anti-tumor and anti-carcinogenic properties and a remedy for hepatitis B viral infection. Due to its beneficial properties, P. niruri is overharvested and wild plants become scarce. This study was conducted to develop an appropriate in vitro culture protocol for the mass production of P. niruri. An aseptic culture of P. niruri was established followed by multiplication of explants using different types of basal medium and its strength and plant growth regulators manipulation. This study also established the induction of in vitro rooting utilizing various types and concentrations of auxin. Treatment of Clorox® with 30% concentration showed the lowest percentage (%) of contamination, 4.44% in P. niruri culture. Nodal segments of P. niruri were successfully induced in full-strength of Murashige and Skoog (MS) basal media with 2.33 number of shoots, 3.11 cm length of shoot and 27.91 number of leaves. In addition, explants in full-strength MS media without any additional cytokinin were recorded as the optimum results for all parameters including the number of shoots (5.0 shoots), the length of shoots (3.68 cm) and the number of leaves (27.33 leaves). Treatment of 2.5 µM indole-3-butyric acid (IBA) showed the highest number of roots (17.92 roots) and root length (1.29 cm). Rooted explants were transferred for acclimatization, and the plantlet showed over 80% of survival rate. In conclusion, plantlets of P. niruri were successfully induced and multiplied via in vitro culture, which could be a step closer to its commercialization.

Protocol for mass propagation of Bambusa bamboos (L.) Voss was developed through in vitro culture. Nodal segments containing pre-existing axillary bud, after surface sterilization, were inoculated on liquid Murashige and Skoog’s (MS) basal medium containing different concentrations and combinations of cytokinins (BAP, TDZ and Kn). The highest direct shoot induction (90%) was obtained in the MS liquid medium supplemented with 2.0 mg/l BAP and 1.0 mg/l TDZ with maximum average number of shoots (3.14 ± 0.06) per explant. Highest shoot multiplication (16.58 ± 0.24 shoots per culture) with highest average shoot length (9.21 ± 0.13 cm) was obtained when in vitro raised shoots were cultured in gelrite gelled MS medium in conjunction with 2.0 mg/l BAP and 1.0 mg/l TDZ. Incorporation of 10% coconut water with 4% sucrose in the above mentioned medium resulted satisfactory shoot growth and development with an average 26.7 ± 0.60 shoots per culture. For root induction, in vitro raised shoots were divided into clumps of 4-5 shoots in each clump and transferred onto both liquid and gelled half-strength MS medium containing different concentrations and combinations of auxins (IBA and NAA). Maximum rooting (86.67%) was achieved in half-strength of MS medium fortified with 2.5 mg/l IBA and 2.5 mg/l NAA with an average 8.72 ± 0.42 root per shoot. The rooted plantlets were then transferred to polybags containing garden soil, sand and compost mixture with 1:1:1 ratio. After a month the hardened plantlets were then transferred to the larger pots containing garden soil and compost with 1:1 ratio for sufficient growth and finally transplanted to the field. In this process, the highest 100% survivability was recorded from well-established rooted plantlets. The regenerated plants showed well developed root and shoot systems in field condition.Jahangirnagar University J. Biol. Sci. 5(2): 15-26, 2016 (December)

Nauclea Diderrichii

Nauclea diderrichii is a tree species of economic importance. However, its plantation establishment is limited by inadequate seedling production. Hence, there is ample scope of tissue culture for its mass propagation. Its in vitro plantlets development as affected by media strengths indicated that 100 % seed germination was obtained in full MS basal medium while the least (3.35 %) was from quarter-strength at 8 Weeks after inoculation (WAI). The effects of BAP and NAA assessed on the growth of its sub-cultured plantlets showed that highest number of leaves (17) and adventitious shoots (3) were obtained from MS basal medium supplemented with 0.1 mg/l BAP only. Whereas, highest shoot length (3.61 cm) and average number of roots (5/plantlet) were obtained from the same medium without hormone(s) at 8 WAI. Further sub-culturing into MS with 0.05 mg/l NAA resulted into plantlets having optimum shoot and massive root growth ready for acclimatization in 6 WAI. The plantlets were successfully acclimatized using coconuthusk/ topsoil mixture with 90 % survival. Plant Tissue Cult. & Biotech. 31(1): 51-60, 2021 (June)

Laurus Nobilis

Laurus nobilis L. is among the species which are most threatened by massive degradation in Morocco. The multiplication by seed or by cuttings gives very low percentages of recovery that is insufficient to meet the demand of growing market. In vitro culture proves to be a tremendous asset to solve this problem. Our work has focused on the study of seed germination of this species and its multiplication from microcuttings. Finally, we studied the ac-climatization ability of the plantlets resulting from this germination. The study of the germination, via the further measurement of the length of the aerial part and the roots and the number of axillary buds for nine weeks, showed that the MS basal medium was more efficient than media 1/2M.S and WPM. Among the eight tested hormones, IAA yielded the best growth of the plantlets. Hormonal combination of NAA and kinetin resulted into a per-centage of the greatest success in reaching 67 % micropropagation. The study also revealed that the MS basal medium in the presence of the IAA plants can acclimate most easily in two types of substrates with improved development in the peat alone.

An efficient in vitro regeneration system was developed for Rauvolfia serpentina L. through direct and indirect organogenesis from nodal and leaf explants. Among the different growth regulators, MS medium supplemented with 2.0 mg/l BAP, 0.5mg/l IAA and 0.02mg/l NAA found best for the multiple shoot formation from nodal segments. In this combination 98% explants produced multiple shoots and the average number of shoots per explants is 13∙4. The frequency of callus induction and multiple shoot induction from leaves was highest 88% in MS medium supplemented with 2.0 mg/l BAP, where mean number of shoots/explants was 12.5. The highest frequency of root induction (80%) and mean number of roots/plantlets (10) were obtained on half strength of MS medium containing 0.2 mg/l IBA. The rooted plantlets were transferred for hardening following acclimatization and finally were successfully established in the field.Bangladesh J. Sci. Ind. Res.53(2), 133-138, 2018

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.

Multiple shoots were obtained from both shoot tips and nodal segments cultured on MS fortified with different concentrations of BAP and Kn singly or in combination with low concentration of NAA. Maximum number of shoots (9.28 ± 0.61) were found on MS supplemented with 1.5 mg/l BAP and 05 mg/l NAA. In vitro regenerated shoots were separated and transferred onto half and full-strength MS supplemented with different concentration of IBA, IAA and NAA for root induction. Full strength MS containing 0.2 mg/l IBA was found to be best for root induction where 93.33% shoots were rooted. In vitro regenerated plants grew normally without showing any morphological variation and flowered after 40 days of transplantation.

Artificial Seed Production

Context: The application of encapsulated shoot tips and nodal segments may contribute to the protection of rare and threatened medicinal plants. Although the artificial seed technique has been reported for more than two decades, for medicinal plants this method has not been developed sufficiently. The main limitations in conventional propagation of some species with medicinal value are: reduced endosperm, low germination rate and seedless varieties. The above mentioned reasons indicate the need for the production of artificial seeds as a technique which combines the advantages of clonal multiplication with those of seed propagation and storage. Objectives: The objective of the present investigation was to standardize artificial seed production technology taking shoot tip and nodal explants in Mentha arvensis and its in vitro regeneration Materials and Methods: Sodium alginate beads were produced by encapsulation of shoot tip and nodal segments of the plant M. arvensis. MS medium was used as basal medium with agar and sodium alginate was used as gelling agent accompanied by CaCl2 solution. Results: Different concentrations and combinations of BAP, Kin and NAA were used in alginate bead in MS basal medium. Among the different concentrations of phytohormone, highest 80% of shoot formation was observed in MS medium containing 2.0 mg/l BAP + 0.2 mg/l NAA from nodal segments of M. arvensis. Highest average number of shoot 9.87 ± 0.58 formation was obtained in the same medium but highest length of shoot 6.27 ± 0.29 cm was found in the medium having 1.0 mg/l BAP + 0.5 mg/l NAA. Conclusion: The present investigation clearly established and demonstrated the method of obtaining the artificial seed production in M. arvensis supported by different hormone concentrations DOI: http://dx.doi.org/10.3329/jbs.v20i0.17722 J. bio-sci.  20:  99-108, 2012
