A new protocol has been developed for cell culture and in vitro regeneration of Abrus precatorius that holds enormous potentiality for preparation of medicines. In vitro grown calli were cultured in Murashige and Skoog (MS) liquid media in agitated condition fortified with 0.5 mg/l 6-Benzylaminopurine. Growth curve of cells revealed that the cells continued to grow until 12 days of culture and got the highest peak from day 6-8. Isolated cell was found to produce highest 8.2% calli when suspended on MS medium supplemented with 0.5 mg/l 6-Benzylaminopurine and 0.1 mg/l 1-Naphthaleneacetic acid. Callus derived from single cell produced highest number of embryo (25-28%) cultured on MS medium fortified with 2.0 mg/l 6-Benzylaminopurine and 0.2 mg/l 1-Naphthaleneacetic acid. The bipolar embryos were selected and optimum shoot formation was recorded on MS medium supplemented with 2.0 mg/l 6-Benzylaminopurine and 0.1 mg/l 1-Naphthaleneacetic acid. The optimum root induction was noticed in MS medium supplemented with 1.0 mg/l 3-Indolebutyric acid. Rooted plantlets were successfully transferred to potting soil and acclimatized to outdoor conditions.

Present investigation was undertaken to standardize technique for in vitro micro-propagation of chickpea( Cicer arietinum ) cultivar Vishwas (Phule G 12). Micropropagation method for chickpea was established and this method enabled much more efficient propagation of plants. The present work was aimed at evolving a protocol for rapid multiplication of chickpea using micropropagation technique. Explants from shoot tip and node segment were cultured on MS medium supplemented with different concentrations of BAP and Kinetin (1.0 to 2.5 mg/l) and their growth responses like shooting were elucidated. The maximum multiple response was observed with 2 mg/l concentration of BAP from both types of explant. The highest number of shoots (12.5 ± 0.3) was achieved on MS medium with 2 mg/l BAP using node segments. The medium supplemented with 2 mg/l of BAP was found better than all other concentrations. Individual shoots were transferred to IBA and IAA (1.0-1.5 mg/l) for root induction. MS medium supplemented with 2 mg/l of IBA proved better for rooting. Rooted plantlets were successfully hardened in greenhouse and established in the pot.

Amygdalus Communis

The Almond (Amygdalus communis) is one of the most important and oldest commercial nut crops, belonging to the Rosaceae family. Almond has been used as base material in pharmaceutical, cosmetic, hygienically and food industry. Propagation by tissue culture technique is the most important one in woody plants. In the current research, in vitro optimization of tissue culture and mass production of almond was investigated. In this idea, explants of actively growing shoots were collected and sterilized, then transferred to MS medium with different concentrations and combinations of plant growth regulators. The experiment was done in completely randomized blocks design, with 7 treatment and 30 replications. After 4 weeks, calli induction, proliferation, shoot length and number of shoot per explants were measured. Results showed that the best medium for shoot initiation and proliferation was MS + 0.5 mg/l IAA (Indol-3-Acetic Acid) + 1 mg/l BA (Benzyl Adenine). Autumn was the best season for collecting explants. The shoots were transferred to root induction medium with different concentrations of plant growth regulators. The best root induction medium was MS + 0.5 mg/l IBA (Indol Butyric Acid).

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.

To evaluate an efficient protocol for the micropropagation of Tupistra albiflora K. Larsen, the effects of N6-benzylaminopurine (BA) and naphthalene acetic acid (NAA) concentrations on multiple shoot and root induction were examined. In vitro shoots were used as the explant materials which were cultured on Murashige and Skoog (MS) agar medium supplemented with 0, 1, 2, 3 and 4 mg/L BA for 4 weeks to induce multiple shoots. It was found that the MS medium containing 3 mg/L BA induced 100 % shoot formation with the highest number of 3.2 shoots per explant (2.4-fold significantly higher than the control). For root induction, in vitro shoots were cultured on MS agar medium supplemented with 0, 1, 2, 3 and 4 mg/L NAA for 8 weeks. The results showed that the MS medium containing 1 mg/L NAA induced 100 % root formation with the highest number of 6.6 roots per explant (1.8-fold significantly higher than the control).

Purpose. The biological characteristics of Fusarium solani clinical corneal isolates growing in different nutritional conditions in vitro were studied in order to find out the key point of pathogenicity. Methods. Five kinds of media with different glucose and nitrogen concentrations were prepared as the liquid and solid forms. The clinical isolates were as follows: 2 Fusarium solani strains. The clinical corneal isolates and the standard strains were inoculated in the solid and liquid media. They were all incubated at 296 for 96 h and observed at defined time points. The optical density was recorded to generate the growth curves in liquid media. Morphologic changes of colonies in the solid media were determined under the light microscope. Results. The clinical isolates of Fusarium solani showed stronger reproductive capacity in the abominable nutritional condition. Besides, when the glucose concentration in the medium was consistent with the glucose concentration of aqueous in diabetic patients, the clinical isolates would show the biological features of quicker growth rate and stronger reproductive capacity. Conclusions. Nitrogen source is essential for fungus reproduction. The clinical isolates showed stronger environmental adaptability under different nutritional conditions and more sensitive to environmental changes.

The emergence of infectious diseases, particularly staphylococcal infections, treatment failures and the more high cost of treatment of infections caused by resistant staphylococci called to find other care alternatives. This study was initiated to evaluate the antibacterial activity of the aqueous extract from Garcinia kola almonds on the in vitro growth of Staphylococcus aureus strains. The methods of diffusion in agar and liquid media were used for susceptibility testing and MIC and MBC determination. The tests were performed on four strains of S. aureus and one reference strain. The minimum inhibitory concentrations of the extracts ranged from 3.12 mg/mL and 12.5 mg/mL and the minimum bactericidal concentrations between 6.25 mg/mL and 25 mg/mL. The lowest value of MIC and MBC was observed with S. aureus ATCC 29213 while the greatest value of these same parameters was obtained on S. aureus 993C/18 and S. aureus 1075C/18. The aqueous almonds extract of Garcinia kola had a bactericidal activity on all the strains of S. aureus studied. This could justify the use of Garcinia kola almonds in the treatment of various diseases in traditional society.

An efficient in vitro regeneration system was developed for Rauvolfia serpentina L. through direct and indirect organogenesis from nodal and leaf explants. Among the different growth regulators, MS medium supplemented with 2.0 mg/l BAP, 0.5mg/l IAA and 0.02mg/l NAA found best for the multiple shoot formation from nodal segments. In this combination 98% explants produced multiple shoots and the average number of shoots per explants is 13∙4. The frequency of callus induction and multiple shoot induction from leaves was highest 88% in MS medium supplemented with 2.0 mg/l BAP, where mean number of shoots/explants was 12.5. The highest frequency of root induction (80%) and mean number of roots/plantlets (10) were obtained on half strength of MS medium containing 0.2 mg/l IBA. The rooted plantlets were transferred for hardening following acclimatization and finally were successfully established in the field.Bangladesh J. Sci. Ind. Res.53(2), 133-138, 2018
