Original Abstract

Diurnal changes of ribulose-1,5-bisphosphate carboxylase/oxygenase activity and its amount were measured to find the mechanism of Rubisco activity regulation in Norway spruce needles. Relatively low morning and evening values of total activities indicate that nocturnal inhibitor CA1P is important in Norway spruce. However, the midday depression of total activity indicates that besides CA1P there have influence some other inhibitors of Rubisco. The diminution of Rubisco amount during the day may indicate repression of its gene expression.

Keywords
