Indigenous Forest

Radermachera xylocarpa (Roxb.) K. Schum. is a rare indigenous forest tree species which is utilized for its wood and medicinal properties. Due to its overexploitation and specific habitat requirements the species is restricted to limited areas. In vitro mass propagation of tree species faces various challenges and no such efforts have yet been taken in propagation of this useful plant using these methods.  In order to overcome the hurdles and understanding an urgent need of its conservation and mass propagation present authors attempt to develop a simple effective tissue culture protocol for regeneration of R. xylocarpa. Nodal explants were cultured on MS supplemented with various concentrations of cytokinins and auxins.  Among different cytokinins, maximum bud induction and proliferation was obtained in media supplemented with Kn along with IBA and for effective root induction which is tough to obtain in tree species, 100% rooting was achieved in cultures with increasing concentrations of IBA. Field survival is a major challenge with regenerated plants of forest tree species. We report here for the first time 100% survival of plants in soil by carefully standardizing the period of hardening and acclimatization procedures. A novel and effective in vitro regeneration protocol of R. xylocarpa has been successfully standardized which can be adopted for large scale propagation, reforestation and conservation of rare Radermachera xylocarpa of medicinal importance.Plant Tissue Cult. & Biotech. 23(1): 21?29, 2013 (June)DOI: http://dx.doi.org/10.3329/ptcb.v23i1.15556

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)

Context: It is necessary to focus on the importance of adopting micropropagation technique for mass propagation of the plantlets in commercial scale as well as conservation and distribution of germplasm. Objective: The present investigation has been designed with a view to establishing protocol of in vitro regeneration of medicinal plant species i,e., Vitex nigundo L (Verbenaceae). Materials and Methods: Shoot tips and nodal segments were used for multiple shoot induction. All explants were cultured on MS medium supplemented with various plant growth regulators. HgCl2 was used as surface sterilizing agent. For in vitro rooting, individual shoots (3-4 cm) were cut from the proliferated shoot cultures and implanted on half and full strength of MS with different concentrations and combinations of NAA and IAA. The cultures were incubated for 16 h photoperiod at 25 ± 2ºC under a fluorescent light. Visual observation of culture was made every week. Data on shoot induction and proliferation and root induction were recorded after three weeks of inoculation and used for calculation. For each treatment 15 explants were used and all the treatments were repeated thrice. Established plantlets were transplanted in earthen pots under natural conditions and the survival rate was recorded. Results: The most effective surface sterilization treatment has been found 0.1 % HgCl2 for 7 minutes. Highest number of shoot was observed in MS medium supplemented with 3.0 mg/ BAP. It was rooted well in full MS containing 2.0 mg/l IAA. The survival rate was 85 % and propagated plantlets were successfully acclimatized in soil. Conclusion: It was observed that shoot tips are more responsive for micropropagation of Vitex nigundo L . Thus the fruitful utilization of rapid clonal propagation, germplasm conservation and distribution of Vitex nigundo, important medicinal plant of Bangladesh, is possible.

This study was conducted to investigate the possibility of obtaining plantlets via somatic embryogenesis and organogenesis as means of in vitro mass propagation in Allium victorialis var. platyphyllum Makino, one of the most popular wild vegetable plants in Korea. Shoots formed directly when bulb explants of A. victorialis were cultured on MS medium containing 0.2 mg·L–1 NAA and 2.0 mg·L–1 zeatin under 16 hours (light)/8 hours (dark) illumination. The use of leaf and shoot tip explants was not successful, largely due to explant senescence in the present of plant growth regulators. Embryogenic calli were obtained from the bulb explants of A. victorialis on MS medium supplemented with 0.2 mg·L–1 NAA, 0.2 mg·L–1 BAP, and 1.0 mg·L–1 picloram after 4–5 weeks of culture in the dark at 27°C. Upon transfer to shoot-induced MS medium containing 0.2 mg·L–1 NAA and 2.0 mg·L–1 zeatin, embryogenic calli gave rise to numerous somatic embryos, which subsequently developed into multiple shoots after 3 months of culture under 16 hours(light)/8 hours (dark) illumination. For root induction, regenerated shoots were transferred to MS medium added with 1.0 mg·L–1 NAA. Regenerants with well-developed roots were potted in an artificial soil mixture of vermiculite (1) and perlite (1).

Present investigation was undertaken to standardize technique for in vitro micro-propagation of chickpea( Cicer arietinum ) cultivar Vishwas (Phule G 12). Micropropagation method for chickpea was established and this method enabled much more efficient propagation of plants. The present work was aimed at evolving a protocol for rapid multiplication of chickpea using micropropagation technique. Explants from shoot tip and node segment were cultured on MS medium supplemented with different concentrations of BAP and Kinetin (1.0 to 2.5 mg/l) and their growth responses like shooting were elucidated. The maximum multiple response was observed with 2 mg/l concentration of BAP from both types of explant. The highest number of shoots (12.5 ± 0.3) was achieved on MS medium with 2 mg/l BAP using node segments. The medium supplemented with 2 mg/l of BAP was found better than all other concentrations. Individual shoots were transferred to IBA and IAA (1.0-1.5 mg/l) for root induction. MS medium supplemented with 2 mg/l of IBA proved better for rooting. Rooted plantlets were successfully hardened in greenhouse and established in the pot.

Amygdalus Communis

The Almond (Amygdalus communis) is one of the most important and oldest commercial nut crops, belonging to the Rosaceae family. Almond has been used as base material in pharmaceutical, cosmetic, hygienically and food industry. Propagation by tissue culture technique is the most important one in woody plants. In the current research, in vitro optimization of tissue culture and mass production of almond was investigated. In this idea, explants of actively growing shoots were collected and sterilized, then transferred to MS medium with different concentrations and combinations of plant growth regulators. The experiment was done in completely randomized blocks design, with 7 treatment and 30 replications. After 4 weeks, calli induction, proliferation, shoot length and number of shoot per explants were measured. Results showed that the best medium for shoot initiation and proliferation was MS + 0.5 mg/l IAA (Indol-3-Acetic Acid) + 1 mg/l BA (Benzyl Adenine). Autumn was the best season for collecting explants. The shoots were transferred to root induction medium with different concentrations of plant growth regulators. The best root induction medium was MS + 0.5 mg/l IBA (Indol Butyric Acid).

Physalis Angulata

Physalis angulata L. is an important medicinal herb. An efficient direct adventitious plant regeneration protocol was developed for large scale propagation using leaf disc as explants. The explants were cultured on MS basal medium supplemented with 0.25-3.0 mg/L 6-benzyl amino purine (BAP) for primary shoot proliferation. Inclusion of indole-3-acetic acid (IAA) and gibberellic acid (GA3) in the culture medium along with BAP promoted a higher rate of shoot multiplication. The maximum number of shoots was produced in MS + BAP (1.0 mg/L) + IAA (0.5 mg/L) + GA3 (0.20 mg/L) after the third subculture. An average of 152.8 ± 0.40 shoots were produced from each leaf disc. For root induction the shootlets were transferred to MS medium supplemented with different concentrations of indole-3-butyric acid (IBA). The highest percentage of root induction was observed in 1.0 mg/L (IBA). Rooted plants were successfully established in the soil after hardening. The survival percentage of rooted plants on soil was found to be 85%. This result will facilitate the conservation and propagation of the important medicinal herb Physalis angulata L.

Embryogenic Callus Induction

<p>Somatic embryogenesis is a technique for regenerating embryos derived from somatic cells of various plant species. This technique along with the utilization of plant growth regulator (PGR) might benefit for mass propagation and improvement of plant species through biotechnological tools. The study aimed to determine the effect of different plant growth regu-lators, namely 6-benzyladenine (BA) and thidiazuron (TDZ) on the embryogenic callus induction as well as casein hydrolysate and malt extract on the somatic embryo development of mangosteen. The explants used were in vitro young stems of mangosteen clone Leuwiliang. This study consisted of two experiments, namely induction of embryogenic callus and formation of somatic embryo. The first experiment was arranged as factorial in a completely randomized design with BA (0 and 0.7 mg l-1) as the first factor and TDZ (0, 0.1, 0.5 and 1.0 mg l-1) as the second factor. The second experiment consisted of four treatments, i.e. casein hydrolysate and malt extract at the rate of 500 and 1,000 mg l-1. The results showed that the best medium for embryogenic callus induction was MS supplemented with 0.1 mg l-1 TDZ, which resulted semifriable calli. Casein hydrolysate and malt extract could not induce the formation of somatic embryos. After two times subcultures on the same MS medium supplemented with 0.5 mg l-1 TDZ and 0.7 mg l-1 BA, a total of 33.8 somatic embryos per explant was induced. The successful somatic embryogenesis would support mangosteen breeding and in vitro mass propagation program.</p>

To evaluate an efficient protocol for the micropropagation of Tupistra albiflora K. Larsen, the effects of N6-benzylaminopurine (BA) and naphthalene acetic acid (NAA) concentrations on multiple shoot and root induction were examined. In vitro shoots were used as the explant materials which were cultured on Murashige and Skoog (MS) agar medium supplemented with 0, 1, 2, 3 and 4 mg/L BA for 4 weeks to induce multiple shoots. It was found that the MS medium containing 3 mg/L BA induced 100 % shoot formation with the highest number of 3.2 shoots per explant (2.4-fold significantly higher than the control). For root induction, in vitro shoots were cultured on MS agar medium supplemented with 0, 1, 2, 3 and 4 mg/L NAA for 8 weeks. The results showed that the MS medium containing 1 mg/L NAA induced 100 % root formation with the highest number of 6.6 roots per explant (1.8-fold significantly higher than the control).
