| Abstract: | Glutamic acid dehydrogenase (GDH) activity was measured in linseed Linum usitatissimum ev. SH-1 at different growth intervals under normal and long photoperiodic conditions. In ungerminated seeds a low activity of GDH was recorded which increased rapidly during germination and thereafter decreased to a level when no GDH activity could be detected at 47 days of growth. An increase in its activity was recorded at 67, 87 and 107 days. Longer photoperiod (continuous light) increased the activity in roots markedly as compared to shorter photoperiods (normal days). |
