Important Medicinal Plant

Acorus calamus L. is a species of enormous medicinal and economic importance. In vitro propagation of this plant was achieved using axillary bud explant. In the present investigation, naturally grown axillary bud and rhizome explants were cultured on standard MS and B5 medium supplemented with different concentration and combination of cytokinines and auxines. The best shoot proliferation was observed in MS medium containing Kn (1.0mg/l) +IBA (0.5mg/l) with 3.33±0.58 nos. of Shoots, 7.33±0.58 nos. of roots and 15.33±0.58 nos. leaves. In B5 medium best results found in Kn (1.5mg/) + NAA (1.0mg/l) with 2.67±0.58 nos. shoots, 3.67±0.58 nos. of roots and11.67±0.58 nos. of leaves. They were then transplanted in soil: sand: cow dung mixture (1:1:2) and kept in shade for 4 to 5 weeks and then transferred to field for one month. Survival rate was found 80 % in MS medium and 100 % in B5 medium. The present investigation was carried out with a view to standardize an in vitro culture technique for mass propagation of this important medicinal plant species and was found successful.

It has been previously demonstrated that thidiazuron (TDZ) enhanced the regeneration and multiple shoot proliferation of vinifera grape cultivars. To determine the effect of TDZ on the multiplication of hybrid grapes, in vitro nodal segments from cultivars Chancellor, Leon Millot, and Valiant were cultured on MS medium supplemented with 0, 0.01, 0.05, 0.1, 0.5, and 1.0 mg TDZ/liter. After 1 month, the higher percentage of rooted shoots was obtained from the explants cultured in medium containing the lowest concentration of TDZ (0.01 mg–liter–1) independent of the genotype. Multiple shoot proliferation was favored by high concentrations of TDZ (0.5 and 1.0 mg–liter–1). An average of 0.39 and 0.39 shoots, respectively, was obtained from `Chancellor' cultures, 0.56 and 0.59 from `Leon Millot', and 1.93 and 2.38 from `Valiant'. Vitrification and teratological structures were observed in all the cultures of the three genotypes, but less vitrification occurred in `Valiant' plantlets.

The present study reports a simple protocol for in vitro regeneration of Aglaonema ‘Valentine’ using axillary shoot explants for rapid multiplication and production of true-to-type plants. Different concentrations of benzyladenine (BA; 0, 1, 3, 5, and 7 mg·L−1), kinetin (Kin; 0, 1, 3, 5, and 7 mg·L−1), thidiazuron (TDZ; 0, 0.5, 1.0, 1.5, and 2.0 mg·L−1), naphthalene acetic acid (NAA; 0, 0.5, and 1.0 mg·L−1), and indole-3-butyric acid (IBA; 0, 0.5, and 1.0 mg·L−1) were used for shoot regeneration. The highest shoot proliferation (5.0) was obtained on Murashige and Skoog (MS) medium supplemented with 1.5 mg·L−1 TDZ and 1 mg·L−1 NAA. In vitro rooting was easily achieved with 100% at all concentrations of NAA and IBA supplemented to half- or full-strength MS medium. Regenerated plantlets were acclimatized in greenhouse with 100% survival rate. Randomly amplified polymorphic DNA (RAPD) analysis confirmed the genetic fidelity of the regenerated plantlets and mother plant.

We can see Orchids come in a wide variety of shapes, sizes, colours, and textures far beyond the human mind’s imagination. They emerge from seeds in nature, but in the absence of suitable hosts, they do not germinate in sufficient numbers. This problem was solved by using the tissue culture technique for its germination. One of the successful method used for mass propogation of orchid plantlets is in vitro techniques. Therefore, an initial analysis was conducted in order to establish an appropriate procedure for mass multiplication of Arundina graminifolia. MS (Murashige and Skoog) medium was found to be suitable for the asymbiotic seed germination of Arundina graminifolia. Direct protocorm like bodies were induced by using combinations and individual supplement of MS medium with IAA (Indole-3-acetic acid), IBA (Indole-3- butyric acid), BAP (6-Benzylaminopurine) and KIN (Kinetin). Hormone-free MS basal medium was found suitable for the conversion of PLBs (protocorm-like bodies) into complete plantlets

To establish a mass micropropagation procedure for Cephalotus follicularis, the effects of varying the strengths of solid Murashige and Skoog (MS) medium were investigated using subcultured shoot explants. After a 60-day primary culture from root mass, the regenerated shoot explants were subcultured every 60 days in solid MS medium. To facilitate shoot proliferation, liquid MS medium was applied with or without exogenous auxin and cytokinin. Our results demonstrate that shoot proliferation and survival of C. follicularis is most effective in modified MS (MMS) medium containing one-fifth or one-tenth strength macronutrients and full-strength micronutrients. Successful shoot proliferation and development of C. follicularis explants were obtained in one-fifth or one-tenth modified liquid MS medium without auxin and cytokinin or with addition of 5 μM indole 3-acetic acid/1 μM N6-benzyladenine for 45 days. The liquid medium consistently produced more explants than the solid medium and shortened the culturing time. Plantlets cultured in hormone-free one-fifth MMS medium developed greater root systems. Using the liquid culture we established, vigorous plants with extensive roots were obtained within 4 months. Plant survival in the greenhouse reached 100%.

The present investigation was conducted for mass multiplication of Jatropha curcas L. through axillary bud culture. For this nodal segment from 3-5 months old nursery grown plants were used as explants for axillary bud culture. The sterilization treatment involving dipping explants in 0.1 per cent HgCl2 solution for 5 minutes resulted in minimum contamination and maximum establishment of nodal explants. The treatment MS medium supplemented with 1.0 mg/L BAP and 1.0 mg/L IAA was the best for culture establishment, shoot proliferation and multiplication of the axillary buds which exhibited highest value in each parameter like establishment (76.1%), number of days taken for shoot initiation (3.1 days), length of longest shoot (6.8 cm), number of leaves on main shoot (7.1) and number of shoots per explant (6.3). Among different treatments for root initiation, half MS media fortified with 1 mg/L IBA, 3 mg/ L NAA and 0.25 g AC gave best result in maximum number of rooting percentage (60) with minimum time taken for root initiation (13.3 days), produced maximum number of roots per shoots (5.1) and length of longest root (4.9 cm) when established shoots were treated with it. Such produced plantlets showed nearly cent per cent survival after hardening and acclimatization. It showed that explants surface sterilized with 0.1 per cent HgCl2 solution for 5 minutes inoculated in MS medium supplemented with 1.0 mg/L BAP and 1.0 mg/L IAA and half MS media fortified with 1 mg/L IBA, 3 mg/L NAA and 0.25 g AC were best in shoot establishment and root development respectively for mass multiplication of J. curcas L. through axillary bud culture.

Axillary Bud Culture

Axillary buds of `Valiant' grapevine (Vitis spp.) grown in vitro were transferred onto Murashige and Skoog (MS) medium supplemented with different cytokinin and auxin combinations and concentrations. It was found that culture medium caused statistically important differences in number of nodes, number of fully expanded leaves, number of multiple shoots, number of roots, and length of shoots. MS medium supplemented with 1.0 mg BA/liter in combination with 0.01 mg NAA/L was found to be the best medium for shoot growth and callus production. MS medium supplemented with the combination of 0.5 mg BA/L and 0.01 mg NAA/L was the best medium for explant rooting. The medium containing BA and NAA encouraged better shoot growth than those containing BA alone. When the concentration of BA in the medium was increased, multiple shoot proliferation and teratological structures of explants increased, but the number of small leaves and length of internode decreased. Axillary bud culture led to better shoot growth than was found for shoot apex culture. The presence of leaves positively affected shoot growth from axillary buds. Also placing the axillary buds horizontally onto the medium gave better shoot proliferation and growth than placing them vertically.

The effect of BAP and IBA on in vitro regeneration of four banana cultivars viz. ‘Amritsagar’, ‘Seeded banana’, ‘Sabri’ and ‘Anajee’ was studied. The response of single shoot regeneration from shoot tips of four banana cultivars at different concentrations of BAP was found to be different. The cultivar ‘Amritsagar’ produced the highest percentage (60 %) of single shoot at 4.0 mg/l BAP within 10-15 days. The cultivar ‘Sabri’ and ‘Anajee’ produced lower percentage of single shoots. Rates of shoot multiplication of ‘Amritsagar’, ‘Sabri’, and ‘Anajee’ were 6-7 plantlets/explant, 2-4 plantlets/explant, and 2 plantlets/explant, respectively on medium containing 4.0 mg/l BAP after 30 days of culture. But in subsequent subculture, on the same medium, ‘Amritsagar’ produced the highest number of plantlets (9 plantlets/explant) within the same period of time. The best root formation in multiplied shoots of ‘Amritsagar’ was found on MS medium containing 2.0 mg/l IBA after 15 days of culture. All the in vitro cultured banana plantlets of ‘Amritsagar’ survived when weaned to ex vitro conditions on soil.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16840 Progress.

Morphogenic Callus

In vitro propagation is a method to produce massive healthy new planting materials quickly. An experiment was carried out for morphogenic callus induction and regeneration of a domestic sugarcane variety. The Explants used was an inert folded leaf and incubated on modified MS medium augmented with 1 mg/l, 2.5 mg/l, and 5 mg/l of 2,4-D for callus induction. The leaf calluses were subcultured on MS medium enriched with different growth regulators for shoot initiation and multiplication. The highest percentage of callus formation was achieved in the medium containing 2.5 mg/l of 2,4-D, while the fastest callus initiation was noticed in MS medium supplemented with 5 mg/l 2,4-D, and maximum proliferation and the morphogenic response of callus were obtained in 3rd subculture. Two types of callus observed on the induction medium were dry nodular friable and smooth compact. This highly morphogenic callus was white to white creamy in color and easy to separate.   The highest shoot proliferation rate was found on the medium containing 2 mg/l Kinetin + 1 mg/l IAA and no growth was noticed on the medium containing Kinetin alone. Therefore, the study suggests that the growth hormone of cytokinin in combination with auxin is necessary for in vitro regeneration of sugarcane callus culture.

Important Medicinal Plant

Momordica dioica, Roxb. (Family: Cucurbitaceae) commonly called as Kartoli, is an important medicinal plant, which has remained unexplored from the commercial point of view. Considering its scarce availability and the medicinal importance, in vitro cultures were established. Traditionally, M. dioica has been propagated mainly through its tuberous roots and less commonly by seeds. Germination through seeds is very difficult or impossible because of hard seed coat. As an alternative to traditional methods tissue culture offers an efficient method for propagation of M. dioica. Mature seeds were used for the regeneration of M. dioica. The decoated seeds of M. dioica were cultured on Murashige and Skoog basal medium (MS medium) supplemented with various combinations of Auxins (á – naphthaleneacetic acid) and Cytokinins (N6 - benzyl adenine). MS basal medium supplemented with 4.44 µM and 8.88 µM N6 - benzyl adenine (BA) gave rise to maximum number of shoots in 7-8 weeks. In vitro grown shoots were sub cultured on MS medium supplemented with different concentrations of indole-3-butyric acid (IBA) for root initiation. MS medium with 0.049mM indole-3-butyric acid (IBA) showed rooting in 45 days. The regenerated plantlets were successfully hardened in vermiculite.
