Digitalis trojana Ivanina is a member of the Plantaginaceae family and known by its common name, Helen of Troy foxglove. It is perennial endemic to Çanakkale and Balıkesir, northwestern Turkey. In order to develop an efficient shoot regeneration protocol, the leaf explants of D. trojana were cultured on Murashige and Skoog (MS) medium containing 6-benzyl adenine (0.1, 0.5, 1.0, 3.0, 5.0 mg/L) and α-naphthalene acetic acid (0.1, 0.5, 1.0 mg/L), 3% (w/v) sucrose and 0.8% (w/v) agar. The highest number of regenerated shoots was obtained from leaf explants that were cultured on MS medium with 3.0 mg/L BA+0.1 mg/L NAA. Regenerated shoots were rooted on MS medium without plant growth regulators. Rooted plants (2–3 cm) were separately transferred to pots containing a mixture of peat and perlite (2:1 v/v) and acclimatized successfully in a growth chamber.

Factors such as slow growth, low rates of sexual and asexual reproduction, and viability of seeds among others limit the massive propagation of Agave americana L. by conventional methods. In this study, callus induction and shoot proliferation was determined in A. americana using Murashige and Skoog (MS) medium supplemented with dicholorophenoxyacetic acid (2,4-D) and 6-benzyl adenine (BA). Meristematic tissue was used as the explants, and were placed on MS medium supplemented with 30.0 g·L−1 sucrose with 0.11, 0.18, or 0.45 μm 2,4-D and 11.0, 22.0, 38.2, 44.0, 58.7, or 73.3 μm BA. Treatments were implemented according to factorial experimental design 3 × 6. After 1 month, the number of explants with callus was determined, whereas the numbers of shoots per explant were monitored after 4, 16, 20, and 36 weeks. The maximum percent of explants with callus was obtained with 0.11 μm 2,4-D and 58.7 and 73.3 μm BA, whereas the maximum numbers of shoots per explant (71) were obtained with 0.11 μm 2,4-D and 73.3 μm BA. The effect of different concentrations of indolebutyric acid (IBA) in the rooting of shoots was evaluated. There were no significant effects of IBA on the number of roots, root length, and axillary roots. Plantlets were acclimatized in the glasshouse and they did not show any phenotypic alteration. This is a highly efficient protocol for the in vitro propagation of A. americana via indirect organogenesis.

In vitro propagation has become an effective practice for large-scale production of strawberry plants. The objective of this study was to evaluate the hyperhydricity and the multiplication capacity of two strawberry varieties (Fragaria x ananassa Duch. 'Dover' and 'Burkley') propagated in vitro. Plants maintained in MS medium supplemented with 1.0 mg L-1 BA were individualized and transferred to the same medium solidified with Agar (6.5 g L-1) or Phytagel® (2.5 g L-1) and BA at different concentrations (0; 0.5; 1.0; 2.0 and 3.0 mg L-1). Biochemical and anatomical analyses were carried out, as well as the analysis of the morphological hyperhydricity characteristics. The analysis of data showed: a) the increase in cytokinin concentration increased hyperhydricity frequency in both varieties; b) at concentrations up to 2.0 mg L-1 BA, the replacement of Agar by Phytagel® induced a higher formation of hyperhydric shoots; and c) the addition of BA induced oxidative stress, which is characterized by increased antioxidant activity and lipid peroxidation, as well as alterations at the cellular level, such as malformation of stomata and epidermal cells. In conclusion, the culture medium containing 0.5 mg L-1 BA solidified with Agar provided lower hyperhydricity percentages in association with higher rates of shoot proliferation in strawberry.

Two different methods of in vitro multiplication of Rauwolfia serpentina from nodal explants were compared viz. multiplication via callus morphogenesis and that via shoot proliferation from axillary buds. The second method was found to be far better. The optimum shoot proliferation occurred on Murashige and Skoog (MS) medium supplemented with 1 mg/L naphthalene acetic acid (NAA) and 2 mg/L of benzyl aminopurine (BAP). The best rooting of shoots occurred on MS medium containing 4% sucrose and 1 mg/L of NAA. Solid and liquid MS media were found to be similar in supporting shoot proliferation. The plants produced were successfully hardened and established in soil. An easy, reliable and reproducible protocol was developed for in vitro micropropagation of Rauwolfia serpentina from nodal explants.

Endemic Medicinal Plant

Lychnophora pinaster, known as arnica, is a medicinal plant of the Cerrado ecosystem in Brazil. It is widely used in the form of alcoholic extract for its anti-inflammatory and anesthetic and healing effects on sprains, bruises, and inflammation. Owing to the great difficulty of propagation, it is listed by the Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis in the category of plants vulnerable to extinction. Micropropagation offers a solution to this problem by allowing the preservation and expansion of germplasm. The objective of this research was to establish a protocol for in vitro propagation of arnica. The best medium for germination of arnica embryos and plantlet growth was a quarter strength semisolid Murashige and Skoog medium (MS/4) containing 0.75% (w/v) sucrose. For shoot induction, the best results were obtained on MS/4 with 2.76 μm of benzylaminopurine. Maximum shoot elongation before rooting occurred in the presence of 8.67 μm of gibberellic acid for 19 d. Microshoots were successfully rooted in the presence of 10.7 μm of naphthalene acetic acid for 15 d. After rooted plantlets were acclimatized in a greenhouse for 20 d, the survival rate was 100% when planted in a soil from the area of occurrence of the species, whereas 0% survived when planted in Plantmax.

The artificial rapid propagation system for Swertia conaensis T. N. Ho et S. W. Liu was explored to screen the appropriate plant regeneration method and to provide an efficient propagation mode, useful for artificial breeding technology or for further research and development of the Tibetan endemic medicinal plant. In this study, the most suitable explant and hormone were chosen according to single factor test. Next, the effects of different hormone combinations on basal stem cluster bud induction, callus induction, adventitious bud occurrence and plant regeneration were investigated by using complete combination and orthogonal experiment. The obtained results showed that the explants suitable for in vitro of S. conaensis were stem tips with leaves, which were regenerated through the method of basal stem cluster bud occurrence in the MS medium with 2.0 mg∙L-1 6-BA, 0.5 mg∙L-1 NAA, but the proliferation coefficient was low, only 3.16 after 40 days of culture. Subsequently, the proliferation coefficient failed to improve, irrespective of change of the concentration ratio of 6-BA and NAA. Therefore, in the orthogonal experiment of adding ZT, the MS medium with 1.0 mg∙L-1 ZT, 0.5 mg∙L-1 NAA and 2.5 mg∙L-1 6-BA induced a large number of callus green and compact, with 86.30% callus occurrence rate. After 40 days of culture, the rate of adventitious bud occurrence was 96.55% and the proliferation coefficient was high (10.37). The rooting rate was 100% in the 1/2MS medium with 0.5 mg∙L-1 NAA. The survival rate of regenerated plants was more than 95%. Indirect organogenesis was more efficient than direct organogenesis in in vitro culture of S. conaensis. In this study, the efficient and stable regeneration system of S. conaensis was achieved through the method of explant to callus to adventitious buds, which provided an effective way to an endangered species.

Mandevilla velutina (Mart.) Woodson (Apocynaceae) is a medicinal plant species with antivenom properties, native from Brazilian Savanna regions (Cerrado), which due to overexploitation and habitat deforestation is in danger of extinction. As an initiative for conserving this endangered but economically important plant species, a micropropagation protocol was developed and genotypes were stored in the Germplasm Bank "Cerrado In vitro". For the in vitro propagation of M. velutina, nodal segments were inoculated on Murashige and Skoog (MS) medium supplemented with different concentrations of BA, Zeatin, 2ip, DTT and TDZ. Best multiplication ratio was achieved when to the medium 0.44 µM BA, ranging 1: 6.7, were added. Plantlets cultured on MS/2 medium supplemented with 26.85 µM NAA rooted successfully (50.5%). Although rooted and un-rooted plantlets acclimatized to soil conditions, great losses were observed within un-rooted plantlets, while the rooted presented 100 % survival. It was possible to maintain 43% of the M. velutina germplasm under healthy conditions for six months, with no subcultures, using the MS medium supplemented with 2% sucrose, 13.8 mM spermidine, 2% sorbitol and 2% dextrose.

A mass in-vitro propagation system of Bacopa monniera (L.) Wettst., a traditional medicinal herb, has been developed. Shoot proliferation and growth were greatly influenced by the months of the year during which the explant were collected. High frequency bud break coupled with maximum number of shoots through nodal segment were found in the month of June and August. Of the different growth regulators tried, for in vitro shoot regeneration, MS medium with BAP (1.0 mg/l) induced maximum number of proliferative shoots (65.00±1.453). Multiplication and elongation of the shoots were obtained after regular sub culturing on the same medium after 15-21 days. Rooting from basal end of the shoots occurred on MS medium with the addition of IBA (0.5 mg/l). After a hardening phase of 4 weeks, almost 95% transplantation was success in the field.DOI: 10.3126/on.v8i1.4311

Multiple Shoot Regeneration

An efficient method was developed for regeneration of Asparagus racemosus Wild, from axillary explants. MS media supplemented with different concentrations of cytokinin (BAP) alone or in combination of different concentrations of auxin (NAA or IBA) was tested for their efficiency in multiple shoot induction. High frequency of multiple shoot regeneration was achieved on MS medium supplemented with BAP (0.1mg/l) and NAA (0.05 mg/l). When shoots were well developed they were dissected and subcultured on the same medium to promote more multiple shoots. Eighteen to twenty shoots were obtained on this medium. The shoots were rooted best on half MS medium supplemented with 0.05 mg/l BAP and 1.0 mg/l IBA. Among the five levels of pH tested, 5.7 was the best for multiple shoot proliferation. The result presented here proved to be suitable for the rapid propagation system of A. racemosus.
