Petiolar and distal cotyledonary segments (PCS and DCS) of Albizia chinensis were cultured on Murashige and Skoog's (MS; 1962) medium and induced to form adventitious shoot buds in the presence of either cytokinins 6-benzylamino purine (BAP), kinetin (KN) or thidiazuron (TDZ). Superiority of BAP in inducing shoot bud and differentiation was observed. PCS(More)
Coccinia grandis is a dioecious species of Cucurbitaceae having heteromorphic sex chromosomes. The chromosome constitution of male and female plants is 22 + XY and 22 + XX respectively. Y chromosome of male sex is conspicuously large and plays a decisive role in determining maleness. Sex modification has been studied in hypogynous Silene latifolia(More)
Cytological and immunochemical studies were carried out on dioecious Coccinia indica to understand the genetic control of sex expression. The somatic chromosome number of both the sex forms of C. indica was found to be 2n = 24 and the karyotype shows high homogeneity, though a distinct heteromorphic pair of sex chromosomes is found in male sex forms of C.(More)
In vitro regeneration of plantlets and multiplication of Sesbania bispinosa (Jacq.) W.F. Wight plants from cultured callus tissue were demonstrated. Callus was established from both cotyledons and mature leaflets on Murashige and Skoog (MS) basal medium supplemented with BAP (0.5 mg/l) and 2,4-D (2 mg/l). Callus mediated shoot bud differentiation was(More)
This study reports an efficient and direct shoot bud differentiation and multiple shoot induction from nodal segments of underground stoloniferous rhizomes of Houttuynia cordata Thumb. The frequency of shoot bud regeneration was influenced by the type of cytokinin and concentrations. Among the various concentrations used, benzylaminopurine (BAP, 17.74(More)
To sustain and increase the productivity in a large underground copper mine in India the management of the mine decided to design and develop stopes below the mined out area. For the design of the stopes a detailed stress measurement programme was carried out by hydrofracture method at different depths from the developments available near the pro‐ posed(More)
