摘要：

Incubation of Strelitzia juncea seeds in an oxygen atmosphere resulted in an increase in the G6PDH activity of crude embryo extracts on day one, while radicle protrusion started on day five. Similarly, 6PGDH activity increased over the first 4 d of incubation in oxygen. The ratio of 6PGDH/G6PDH was 3.0< x < 3.7 regardless of treatment or incubation period.Supplying oxygen per se to dormant seed and studying its effect on the activity of the two key pentose phosphate (PP) pathway enzymes, appear to support Roberts' hypothesis that oxygen shortage restricts PP pathway activity in dormant seeds. © 1990 Oxford University Press.
