An efficient protocol was developed for in vitro propagation of Abrus precatorius L. through induction of indirect organogenesis in nodal segment derived callus tissue. Yellowish-green nodular callus was induced at the cut surface of the nodal segments cultured on MS fortified with 5.0 mg/l BAP and 0.5 mg/l NAA. The callus differentiated into adventitious shoots when it was subcultured on to MS supplemented with 3.0 mg/l BAP + 0.5 mg/l Kn + 0.5 mg/l NAA. On an average 6.87 ± 0.26 shoots/culture developed. These microshoots were rooted in half-strength MS containing 1.0 mg/l IBA and the rooted plantlets were transferred to soil after proper acclimatization.Key words: Abrus precatorius, Medicinal plant, Callus culture, PropagationDOI = 10.3329/ptcb.v17i1.1121Plant Tissue Cult. & Biotech. 17(1): 59-64, 2007 (June)

An efficient protocol was established for in vitro clonal propagation of Hemidesmus indicus (Anantamul) belongs to the family Asclepiadaceae, a widely used medicinal plant through callus culture in using nodal segment. Yellowish nodular callus was observed from nodal segments on MS basal medium supplemented with 0.5 mg/L BAP + 0.2 mg/L NAA within four weeks of culture. Large number of shoots (11.4±0.2) and roots (8.2±0.4) were obtained when the callus was sub cultured on MS medium with 0.2 mg/L BAP. The regenerated plantlets were acclimatized by transferring them to soil. The survival rate of plantlets was found to be 90%. Regenerated plants were morphologically comparable having normal leaf shape and growth.

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.

In vitro study was carried out in an important medicinal plant Tinospora cordifolia (Willd.) Miers belonging to the family: Menispermaceae. Vegetative parts such as stem, leaf and nodal explants were excised from an elite in vivo grown mature plant and thereafter cultured on Murashige-Skoog (MS) medium supplemented with different hormonal concentrations for callus induction and organogenesis. Callus formation occurred from nodal segments, leaf and inter-node explants when planted on different combinations of hormones. Tinospora cordifolia showed response for in vitro shoot growth from the nodal segment. The best shoot growth was observed on MS medium supplemented with kinetin (1.5 mg/l). Similarly, the best result for root induction was obtained on MS medium supplemented with 6-benzylaminopurine (1.0 mg/l) and naphthaleneacetic acid (2.5 mg/l).

An efficient in vitro plant regeneration protocol was developed for the medicinally potent plant species Phyllanthus amarus Schum. and Thonn. (Euphorbiaceae) using nodal segment as explant. Maximum multiplication of shoots (15.275±0.96) was achieved on Murashige and Skoog’s medium supplemented with BAP (0.5 mg/l) after 3-4 weeks of inoculation. The shoots were separated from cluster and subcultured for their elongation on the same medium. In vitro flowering was also observed on the elongated shoots after 3–4 weeks of sub culturing on the shoot elongation medium. In vitro rooting was obtained on half strength MS medium supplemented with IBA (0.5 mg/l).  Regenerated plants were successfully hardened and acclimatized, 80 % of plantlets survived well under natural conditions after transplantation.Key words: In vitro regeneration, multiple shoots, nodal segments, Phyllanthus amarusDOI: 10.3126/on.v7i1.2557Our Nature (2009) 7:110-115

In vitro clonal propagation of Clerodendrum serratum L., a rare medicinal plant has been reported by using LM medium supplemented with different growth hormones. The maximum number of shoots with maximum length were obtained from stem derived callus on LM media fortified with 1.5 mg/l BAP and 0.3 mg/l NAA. Nodal explants showed direct organogenesis on LM media containing BAP (0.5 mg/l) alone.

Morphogenesis In Vitro

Abstract Passiflora setacea DC (Passifloraceae) is considered an important species in the genetic breeding of passion fruit. However, its use is limited due to low seed germination. This paper aimed to study the effect of cytokinins 6-benzyladenine (BA) and thidiazuron (TDZ) on the in vitro morphogenesis of P. setacea using three explants: hypocotyl, nodal segment, and root segment. The explants were induced to morphogenesis in MS medium modified and with different concentrations of BA and TDZ. After 55 days, the percentage of calluses and shoots were evaluated, and anatomical characterization was performed. The three explants used in the in vitro morphogenesis of P. setacea showed callus and shoots formation, but in greater numbers in the nodal segments treated with BA. TDZ isolated affected equal to or less than BA on callus and shoots formation for the three explants. Direct and indirect organogenesis was observed in the three types of explants. From the results obtained for plant regeneration via in vitro morphogenesis of P. setacea, it is recommended to use a nodal segment in MSM medium and supplemented with 2.22 μmol L-1 of BA.

Shoot Tip Explants

The present study describes a protocol for high frequency plant regeneration of Physalis minima. Shoots were induced by culturing nodal segments and shoot tips from 15 day old seedlings. About 29 and 32 shoots were found to be induced from nodal segment and shoot tip explants, respectively, cultured on MS medium supplemented with 1.0 mg/l BAP. When shoots were subcultured on the fresh medium with same component as mentioned above, the shoots were elongated. Shoots rooted well when they were excised individually and implanted on half-strength MS medium with 0.3 mg/l NAA, where 98% shoots rooted within 12-15 days. In vitro grown plantlets with strong root system were successfully established in normal room temperature for seven days before transplanting in pots where they were reared for three weeks through successive acclimatization. The regenerated plants were successfully transferred to the soil with 90% survival rate.

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%.
