In Vitro Clonal Propagation

An efficient protocol was established for in vitro clonal propagation of the perennial medicinal herb Scoparia dulcis L. (Family. Scrophulariaceae) through in vitro culture. Apical and axillary buds of young sprouts from selected plants were used as explants. Best shoot induction was observed on MS basal medium supplemented with 0.1 mg/l BAP, in which 94% of the explants produced 12 shoots per culture. Repeated subcultures in the same medium, resulted rapid shoot multiplication with 16 shoots per culture. The half strength MS medium with 0.5 mg/l IBA +0.5 mg/l NAA the highest percentage (85.20) and maximum number (13.40) of roots were initiated within four weeks of culture. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting in pots where plantlets were reared for three weeks. The survival rate of regenerated plantlets was 85%.

A protocol was established for mass propagation of a valuable medicinal herb, Eclipta alba (Linn.) Hassk (Asteraceae) through in vitro culture. Apical and axillary buds of young sprouts from selected plants were used as explants. Best shoot induction was observed on MS basal medium supplemented with 0.5 mgl-1 BAP + 0.1 mgl-1 NAA, in which 94% of the explants produced 18 shoots per culture. Repeated subcultures in the same medium, resulted rapid shoot multiplication with 26 shoots per culture. In vitro raised shoots rooted on half strength MS medium with 1.0 mgl-1 IBA +1.0 mgl-1 NAA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting in pots where plantlets were reared for three weeks.

Green compact nodular callus was observed within three weeks from nodal segments of a perennial medicinal herb Scoparia dulcis L. on MS basal medium supplemented with 1.5 mg/l BAP + 0.2 mg/I NAA. The callus produced large number of shoots when subcultured on MS with 0.5 mg/l BAP + 0.1 mg/l NAA. In vitro raised shoots rooted on half strength of MS with 1.0 mg/l IBA + 1.0 mg/l NAA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for seven days before transplanting in pots where plantlets were reared for three weeks. The survival rate of plantlets was found to be 85%. Regenerated plants were morphologically uniform having normal leaf shape and growth. Key words: Scoparia dulcis, Medicinal plant, Shoot proliferation, Acclimatization D.O.I. 10.3329/ptcb.v18i1.3268 Plant Tissue Cult. & Biotech. 18(1): 75-83, 2008 (June)

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.

In Vitro Clonal Propagation

An in vitro clonal propagation protocol based on axillary bud development was generated for Turbinicarpus valdezianus. An efficient multiplication rate was obtained using either longitudinal or apical explants from in vitro germinated seedlings. The proliferation capacity of these explants was evaluated by testing the single and interaction effects of five concentrations of 6-furfurylaminopurine (KIN) (0.00, 2.32, 4.64, 9.28, and 18.56 µm) and three concentrations of α-naphthalenacetic acid (NAA) (0.00, 0.54, and 2.70 µm), using Murashige and Skoog (MS) as basal medium. Statistical analysis showed that the highest average shoot proliferation of T. valdezianus was recorded with 9.28 µm of KIN, producing 11.75 and 4.50 plantlets per initial explant, for apical and lateral explants, respectively. Addition of NAA to the medium had an inhibitory effect on shoot proliferation for both explant types. The developed shoots in 9.28 µm of KIN and plant growth regulator (PGR)-free treatments were used for a rooting subculture phase. These shoots were then transferred to PGR-free MS medium, resulting in statistically significant different rooting frequencies of 78% and 97%, respectively. When transplanted in soil, the rooted shoots showed an average survival rate of 90%, without any significant statistical differences between treatments. This propagation protocol has the capacity to produce near to 21 plantlets per seedling in 27 weeks, i.e., 11.78 and 9.00 plantlets per apical and lateral explants, respectively, without callus or adventitious shoot formation. These features made it highly attractive as an in vitro clonal propagation method for T. valdezianus plants and the later implementation of a rescue program for threatened wild populations of this cacti species.

Several rose species (Rosa rugosa, R. wichuraiana, R. setigera, R. laevigata, R. banksiae, R. roxburghii, R. odorata and hybrids) were employed to establish the appropriate nutrient media for shoot multiplication and root initiation of cultured shoots and to describe a procedure for the successful transfer to soil of plants obtained in vitro. Cultured shoot tips and lateral buds from different genotypes proliferated multiple shoots on a basal medium (MS salt, vitamins, glycine, sucrose and agar) supplemented with 0mg/l to 6mg/l 6-benzylamino purine (BA) and 0mg/l to 0.5 mg/l naphthalene acetic acid (NAA). Most rose species cultured in a modified MS medium supplemented with 2mg/l BA showed good growth and shoot proliferation. The buds nearest the apex exhibited the slowest rate of bud development. Root development was enhanced and shoot development inhibited by lowering the concentration of MS salts to quarter- and half-strength. With difficult-to-root species, rooting was improved by supplementing the media with auxin or giving them 3-7days of dark treatment.

Shoot tips and nodal explants of young sprouts from selected plants were used as explants. Best shoot induction was observed on MS basal medium supplemented with 0.5 mg/l BAP + 0.1 mg/l GA3, in which 88% of nodal explants responded to produce maximum number (16.8 ± 0.95) of shoots per culture. In vitro raised shoots rooted on half strength MS medium with 0.5 mg/l IBA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting in pots where plantlets were reared for three weeks.
