Abstract
The content of nucleic acids in the cell culture of fern-leaf aralia Polyscias filicifolia (Moore ex Fournter) Bailey (Araliaceae) exposed to heat shock (3 h at 45°C) decreased significantly (by 20–30%). The decrease in DNA and RNA contents was even larger (30–40%) after longer heat shock (24 h). Cold (24 h at 7°C) caused an even more dramatic decrease in DNA (by 34.2%) and total RNA (by 48%) contents. To judge from the DNA production rate, the presence of hydrogen peroxide and phenazine methosulfate in the culture exerted a dose-dependent and differently directed action on cell proliferation.
