Studies on Clonal Propagation of Cattleya through Tissue Culture Method

Tissue culture studies on clonal variations in micropropagation of Dalbergia sissoo

The present study was undertaken to study the in vitro responses of different clones of Dalbergia sissoo. For this study, three clones: one from Uttarakhand (clone No.09), Rajasthan (clone No.59) and Haryana (clone No.79) were investigated. These clones were selected on the phenotypic characters of candidate plus trees namely: higher volume of wood, clean bole length and stem form, etc. These c...

Propagation of Rabies Virus in Tissue Culture

Rabies virus has been propagated in serum-Tyrode solution containing either embryo mouse brain or embryo chick brain. The culture virus reached a titre of 3 x 10(-5) cc. after 4 days' incubation at 37 degrees C., and survived at least 2 months at 5 degrees C. in the liquid or dry state.

Tissue Culture Studies

The content of ribo- and desoxyribonucleic acids in chick heart cultures at regular intervals after implanting has been determined both with standard culture medium and with Tyrode's solution alone. With an inadequate medium, both nucleic acids dropped in a consistent manner but ribonucleic acid was affected to a much greater extent. When the medium was adequate for growth, both fractions rose ...

Tissue Culture Studies on Bacterial Hypersensitivity

1. Mononuclear exudative cells, obtained from tuberculous guinea pigs by the intrapleural injection of parowax, exhibited characteristic sensitivity to the toxic action of tuberculin when tested in tissue culture. 2. Experiments with these cells, practically free of body fluids, show conclusively that sensitivity to tuberculin is an inherent characteristic of mesenchymal cells from tuberculous ...
