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)

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.

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.

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.

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.

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

Plantlets were recovered from axillary bud cultures of muscadine grape (Vitis rotundifolia, `Summit'). Nodal segments 0.5 to 1.0 cm long were cultured in Murashige and Skoog (MS) basal medium supplemented with 5, 10, 20, or 40 μm BA. Best total shoot production was obtained with 10 μm BA; with higher BA levels, shoots were unexpanded and exhibited high mortalities. MS medium supplemented with IBA enhanced rooting by increasing rooting percentage and number per plantlet. Shoots previously proliferated on medium with 5 μm BA rooted significantly better than those multiplied on 10 μM BA. Shoot vigor during rooting was greater in shoots proliferated on 5 vs. 10 μm BA. Root development was not significantly affected by liquid vs. agar-solidifted medium or shoot length. Chemical names used: N-(phenylmethyl) -1H-purin-6-amine (BA), 1H-indole-3-butyric acid (IBA).
