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.

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.

ABSTRACT The aim of this study was to establish the best concentrations of growth regulators for in vitro cultivation of jambu for a subsequent elaboration of an efficient micropropagation protocol. After sterilized, the seeds were inoculated on different media (MS, ½MS and water-agar) for in vitro germination. Nodal segments of in vitro germinated jambu seedlings were used as explants in the micropropagation with different concentrations of 6-benzylaminopurine (BAP) (0.0; 0.125; 0.25; 0.50 and 0.75 mg L-1) and callus induction with 2.4- dichlorophenoxyacetic acid (2.4-D) (0.0; 0.25; 0.50; 0.75 and 1.0 mg L-1) on Murashige & Skoog’s (MS) medium. The highest germination rates were obtained on MS medium with better seedling development and greater height (3.7cm). In micropropagation, the best treatment was obtained on 0.125 BAP (T2), with an average of 2.2 sprouts/explant, average height of 2.4 cm and vigorous sprouts. In callus induction, all treatments with 2.4-D had developed friable calluses in 30 days and using doses of 0.25 and 0.50 mg L-1 provided greater fresh matter. The induction of friable callus and the root production occur without supplementation of exogenous growth regulator.

Hot Climate

Wedelia trilobata (L.) Hitch is a member of Asteraceae (formerly Compositae), the sunflower family. Its common name includes “Wedelia” and trailing daisy, although some people mistakenly call it Singapore daisy. In a wider sense the genus Wedelia, named in honor of Georg Wolfgang Wedel (1645 –1721), Professor of Botany at Jena, Germany, has about 70 species of tropical strand plant, Wollastonia biflora (formerly known as Wedelia biflora), to which it is closely related. In a more narrow sense, and now more widely accepted, Wedelia is considered to be a genus of relatively a few species of strictly American origin, one of which is Wedelia parviceps Blake, a herbaceous or sub-shrubby weed common in croplands, harvested fields, pasteures and roadside bush in hot climate in central America (Garcia et al. 1975). Interestingly, the Hawaiian endemic genus Lipochaeta is scarcely distinct from it genetically, and two sections of Lipochaeta appears to have been independently derived from Wedelia like ancestors (Wagner et al. 1990).   Key words: Wedelia trilobata, Callus induction, In vitro   D.

Jatropha (Jatropha curcas L.) is an oil bearing crop growing in tropical and subtropical parts of the world. The present study was undertaken to investigate the effects of different plant growth regulators on in vitro callus induction in physic nut (J. curcus). In the present study, it was observed that all the explants viz., leaf lamina, petioles, nodal segments and cotyledonary nodes showed good callus induction responses on various culture media thus tried. Leaf lamina and petioles showed 100.0% callus induction responses on different MS media supplemented with auxins and cytokinins alone or in combinations whereas, nodal segments and cotyledonary nodes showed maximum 89.6% and 83.9% callus induction respectively. The presence of 2, 4-D in culture media with auxins or cytokinins was essential for good callus growth. Among different explants tried, leaf lamina was the best responding explants and MS-13 media supplemented with 5×10-6 M NAA and 10-5 M 2, 4-D is the best callusing and growth supporting medium. However, the regenerative competence of the callus tissues can differ depending on the type of explants used because certain types of plant tissues have more favorable regeneration responses than others. Callus induction rate from all explant types was highest than other reports. The results obtained in the present study would facilitate the high callus induction and regeneration responses in J. curcus for its improvement using biotechnological tools.

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.

Trachyspermum Copticum

The effect of explant sources and plant growth regulators on callus induction and plantlet regeneration of Trachyspermum copticum were explored. Different explants including hypocotyl, cotyledonary node and leaf were cultured on MS supplemented with different combinations and concentrations of plant growth regulators including 2,4‐D (0.2‐3 0.5 mg/l), NAA (2 mg/l), BAP (1‐3 mg/l), Kn (0.5 mg/l) and IAA (0.8 mg/l). The best response for callus induction (100%) as well as quality was observed from cotyldonary node segments cultured on MS supplemented with 2, 4‐D at 1 mg/l in combination with Kn at 0.5 mg/l. Calli derived from various explants were subcultured on shoot induction media with different compositions and concentrations of medium. MS without any plant growth regulator promoted the highest frequency of shoot regeneration (100%) and also mean number of developed shoots per explants (3.8) showed the same result. Regenerated shoots were then rooted on three‐fourth strength MS with 75% efficiency after 30 days.Plant Tissue Cult. & Biotech. 27(1): 13-20, 2017 (June)
