Mitochondrial Nucleic Acids from Parthenocissus Tricuspidata Cells
The growth pattern of suspension cultures of Parthenocissus tricuspidata cells has been studied. A nutritive medium derived from that of Heller gives a high yield of metabolically active cells. The cell number, fresh and dry weights, DNA and RNA contents have been followed over a subculture cycle (14 days in defined conditions). A doubling time of 36 hours has been estimated.
