cellular and tissue activities highly depend on environmental ph. murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. we have studied the effect of ph on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. various concentrations of nahc03 were used to adjust the ph of the culture medium under co...

in the present study, 2, 4-dichlorophenoxyacetic acid (2, 4-d) was assessed individually for its effectiveness to induce somatic embryogenesis in tea (camellia sinenesis l.). embryonic axes and cotyledons explants were dissected from the seeds. explants were cultured on murashige and skoog (ms) medium containing 0, 1 and 5 mm 2, 4-d alone for embryonic axes and 0, 1 and 5 mm 2, 4-d along with 0...
