    Plant regeneration from callus cultures of Psoralea corylifolia Linn (1997)
    Springer
    Plant growth regulation 22 (1997), S. 13-17 
    Details
    ISSN: 1573-5087
    Keywords: BA ; in vitro ; medicinal plant ; NAA ; regeneration

    Notes: Abstract Plantlet regeneration via organogenesis was achieved in callus cultures derived form mature leaves, stems and leaves, petioles and roots of young seedling of Psoralea corylifolia on Murashige and Skoog medium supplemented with 2.5–3.0 mg L-1 BA, 1.0 mg L-1 NAA and 3% (w/v) sucrose. The rate of shoot bud regeneration was positively correlated with the concentration of hormones in the nutrient media. Shoot buds regenerated more readily from juvenile explants (seedling source) as compared to the mature explants. Addition of adenine sulphate (5 mg L-1) to the culture medium increased the growth of shoot buds. Optimum responses were obtained in hypocotyl and leaf explants using NAA in combination with BA, the highest rate of shoot bud regeneration being in hypocotyl explants. Rooting was readily achieved on the differentiated shoots on MS basal media without growth regulators. Regenerated plantlets were successfully established in the greenhouse.

    Tolerance of rice to nickel in nutrient solution (1997)
    Springer
    Biologia plantarum 40 (1997), S. 295-298 
    Details
    ISSN: 1573-8264
    Keywords: cultivar differences ; growth parameters ; Oryza sativa
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract For screening tolerance of six cultivars of rice (Oryza sativa) to different concentrations of nickel (0, 6, 12, 18, 24 and 30 μg dm3), growth parameters (root and shoot length, root and shoot dry matter production) and root and shoot tolerance indexes were tested after 7, 10 and 13 d of treatment. In presence of nickel in nutrient solution, root growth of cv. Nilgiri was enhanced, while in cvs. Subhadra, Khandagiri, Rudra, Sankar and Annapurna it decreased. The root tolerance index (RTI) and shoot tolerance index (STI) in cv. Nilgiri were high; cvs. Sankar and Khandagiri, however, showed a low RTI. Based on the standard growth parameters, six cultivars of rice were ranked in respect of their tolerance to nickel: Nilgiri 〉 Annapurna 〉 Subhadra 〉 Khandagiri 〉 Rudra 〉 Sankar.
