Anther of five varieties of Brassica species, namely BARI Shariaha-7, Tori-7, Agrani, Daulat and Safal were cultured in vitro to observe their regeneration potentiality. Different concentrations and combinations of growth regulators were supplemented in MS medium. The range of callus induction was 12.50-87.50 %. Maximum callus induction (75.00%) was observed on MS +4 mg/L 2, 4-D + 1.0 mg/L BAP. Among the genotypes, BARI Sharisha-7 showed the highest percentage of callus induction (60.42%). Among the treatments, highest percentage of shoot regeneration (75.00%) was observed on MS + 4 mg/L BAP + 1.0 mg/L NAA. BARI Sharisha-7 also showed the highest rate of plant regeneration (66.67%). Root induction was highest (75%) on half strength MS medium supplemented with 1.0 mg/L IBA and 0.5 mg/L NAA. The plantlets with sufficient roots thus obtained were transferred successfully to plastic pots and subsequently to the field. BARI Sharisha-7 and Tori-7 survived easily in the pots as well as in the field but Safal was very poor in survivability both in the pots and in the field.

Petiole of six genotypes of oilseed Brassica viz. Tori-7, Sampad, Kallyania, BARI Sarisha-7, BARI Sarisha-8, and MM 20-3 were cultured in MS medium with different concentrations of BAP, NAA, and AgNO3 for callus induction and subsequent plant regeneration. The highest percentage of callus induction (91.43%) was observed in Tori-7 in the media supplemented with 2 mg/L BAP, 0.1 mg/L NAA and 2.0 mg/L AgNO3. Calli were maintained in order to get sufficient number of regenerants. With the increased concentration of BAP, the highest percentage (57.14) of regenerants were found in Tori-7 followed by Sampad (33.13%) and BARI Sarisha-8 (31.42%) in MS media supplemented with 2.5 mg/L BAP, 0.1 mg/L NAA and 2.0 mg/L AgNO3. Root formation from the regenerants was found best in half MS medium supplemented with 0.5 mg/L NAA in genotype Tori-7. Regenerated plantlets of four genotypes (Tori-7, BARI Sarisha-8, Kallyania, BARI Sarisha-7) were successfully established in the field.Keywords: AgNO3; BAP; Brassica; NAA; regeneration.  DOI: 10.3329/bjar.v35i2.5881Bangladesh J.

The present investigation was conducted to develop a protocol for rapid callus induction and plant regeneration from leaf explant of Abutilon indicum L. Callus induction and plantlet regeneration at various frequencies were observed on MS using different concentrations of 2,4-D alone or in combination with BAP and Kn. The highest percentage of callus induction was observed with 2.5 mg/l 2,4-D (90) and with combination of 0.5 mg/l Kn (85). Optimum shoot formation was observed on same medium but supplemented with 2.0 mg/l Kn and 1.0 mg/l NAA (11.2). Rooting experiments with half strength of MS revealed that NAA was more suitable for root induction compared to IBA and IAA. The healthy in vitro rooting plantlets were successfully transferred to the field. The survival of the plantlets under ex vitro condition was 87%. Key words: Abutilon indicum, Callus induction, Leaf explants, Micropropagation D.O.I. 10.3329/ptcb.v19i2.5435 Plant Tissue Cult. & Biotech. 19(2): 177-184, 2009 (December)

<p style="text-align: justify;"><strong>Aim</strong>: To optimize the concentrations of growth regulators in the media for the proficient micropropagation of grapevine (<em>Vitis vinifera </em>L.) cv. King’s Ruby.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Apical meristems of the grape cultivar were used to establish <em>in vitro</em> shoot cultures. Nodal explants, each containing an axillary bud, taken from <em>in vitro</em> grown shoots were inoculated in shoot proliferation medium, i.e., half strength Murashige and Skoog (MS) medium supplemented with benzyl aminopurine (BAP), kinetin, glycine and gibberellic acid (GA<sub>3</sub>). A higher number of shoots (5.33) with greater shoot length (2.75 cm) was produced in the medium supplemented with 1.0 mg L<sup>-1</sup> BAP and 0.1 mg L<sup>-1</sup> GA<sub>3</sub>. Calluses were induced from leaf explants taken from <em>in vitro</em> grown shoots. Callus induction was greater (73.00%) on the medium containing 2.0 mg L<sup>-1</sup> 2,4-dichlorophenoxyacetic acid (2,4-D), 0.3 mg L<sup>-1</sup> BAP and 0.2 mg L<sup>-1</sup> α-naphthaleneacetic acid (NAA). The maximum frequency of shoot regeneration (53.33%) was achieved on the medium supplemented with 1.5 mg L<sup>-1</sup> BAP and 0.5 mg L<sup>-1</sup> NAA, and the regenerated shoots successfully formed roots on growth regulator-free half strength MS medium.</p><p style="text-align: justify;"><strong>Conclusion</strong>: Optimizing the concentration of BAP and GA<sub>3</sub> and omitting the glycine and kinetin in the culture medium increased the number and length of shoots. Similarly, for inducing the callus of the leaf explants, taken from <em>in vitro</em> grown shoots, it is recommended to adjust the medium with the higher concentration of 2,4-D and lower concentrations of BAP. Moreover, the maximum number of shoots was regenerated on a medium supplemented with relatively high levels of both BAP and NAA (1.5 and 0.5 mg L<sup>-1</sup>, respectively). Finally, we suggest the half strength MS medium that is free from growth regulators for the root formation of the regenerated shoots.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: Optimizing the concentration of growth regulators is crucial for the efficient micropropagation of a grape cultivar. Knowing the specific balance between the growth regulators is necessary to establish <em>in vitro</em> shoot cultures, callus induction and shoot regeneration and, hence, to propagate disease-free true to type grape cultivars in a short time.</p>

The experiment was conducted to investigate the performance of three different genotypes (BARI Sarisha-6, BARI Sarisha-8, and BARI Sarisha-11) in two different media viz., MS and B5 with different concentrations of phytohormone (2, 4-D) for callus induction from uninucleate stage anthers of Brassica and subsequent plant regeneration in MS media with different concentrations of phytohormone (BAP and NAA). Among the genotypes, BARI Sarisha-8 showed the best performance for all the parameters of callus induction. The performance of BARI Sarisha-6 was poor compared to others. Maximum rate of callus induction (%) was observed in MS + 0.5 mg/L 2, 4-D followed by B5 + 0.5 mg/L 2,4-D. The media combination MS + 1.0 mg/L BAP 0.3 mg/L 2,4-D showed the best performance for maintenance of calli. Significant variations were observed among the genotypes and media composition for shoot regeneration. Among the genotypes, BARI Sarisha-8 showed the best performance for shoot regeneration followed by BARJ Sarisha-l1. The genotype BARI Sarisha-8 produced higher percent of shoots/calli and required minimum days for shoot initiation. Higher percent calli without shoot were produced by the genotype BARI Sarisha-6. The media combination MS + 2.0 mg/L BAP + 0.5 mg/L NAA showed the best performance for shoot regeneration and required maximum days for shoot initiation.

The experiment was conducted during May to December 2008 in the Biotechnology Laboratory of Bangladesh Agricultural University, Mymensingh to observe the callus induction, regeneration potentiality and to establish a suitable in vitro plantlet regeneration protocol of Corchorus olitorius. MS medium supplemented with different phytohormone concentrations and combinations were used to observe the callus induction, shoot regeneration and root formation ability of the cotyledon with attached petiole derived explant of three genotypes viz. O-9897, O-72 and OM-1. The highest callus induction (92.85%) was observed in O-9897 followed by O-72 (82.14%) in the MS media supplemented with 2.5 mg/L BAP + 0.5 mg/L IAA. Genotype O-9897 in MS media supplemented with 2.5 mg/L BAP + 0.5 mg/L IAA produced the highest percentage of shoot regenerants (83.33%) followed by O-72 (75.00%) in the media supplemented with 2.5 mg/L BAP + 0.5 mg/L IAA. The root formation from regenerants was the best on halfstrength of MS media supplemented with 0.6 mg/L IBA in genotype O-9897 (45.00%). The in vitro regenerated plantlets from the genotypes O-9897 could be established in the field. Therefore, the genotypes O-9897 of C. olitorius in MS media supplemented with 2.5 mg/L BAP + 0.5 mg/L IAA could be used for callus induction and shoot regeneration.

The experiment was designed to evaluate the effect of growth regulators on leaf explant of Gerbera for callus induction. Various kinds of plant growth regulators such as 6-Benzylaminopurine (BAP), α-Naphthalene acetic acid (NAA), 2, 4-Dichlorophenoxyacetic acid (2, 4-D), Indole-3-acetic acid (IAA) were used to initiate cultures. These were added to Murashige and Skoog medium in different combinations and concentrations. Leaf explants cultured on MS medium supplemented with BAP+ 2, 4-D+ IAA in T4 treatment & BAP+ 2,4-D in T5 treatment showed the best results for callus induction. On the other hand callus was induced early in the combination of BA+ 2,4-D + IAA hormone in T5, T9 & T8 treatment respectively. The rate of callus induction was very low in BA + NAA combinations but it was much earlier.

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).
