Utilization of stored nitrate during the anaerobic germination of rice [Oryza sativa] seeds

The presence of nitrate in the seed and its utilization during anaerobic germination of rice (Oryza sativa L.) were studied. The results indicate that nitrate was reduced and assimilated by the coleoptile for 11 days during anaerobic growth after germination. The importance of the anoxic utilization...

Zusammenfassung:	The presence of nitrate in the seed and its utilization during anaerobic germination of rice (Oryza sativa L.) were studied. The results indicate that nitrate was reduced and assimilated by the coleoptile for 11 days during anaerobic growth after germination. The importance of the anoxic utilization of nitrate is discussed.
