Effect of acetate on the contents of nitrate, oxalate and ascorbic acid in spinach
2001
Kikuchi, T. (Utsunomiya Univ. (Japan)) | Sekimoto, H.
To clarify a practical treatment for the production of high quality spinach with reduced nitrate content, we conducted a trial using acetate instead of sulfate and chloride as nutrient salts in the water culture. The treatment (1.5 mM) of acetate for 2 d before harvest obtained the same yield as the control and nitrate content was decreased up to 23% from the control. In contrast, the acetate treatment did not affect the content of oxalate, however ascorbic acid content was inclined to increase with the treatment.
