| Summary: | Effects of selenium (in the form of selenite) on the growth and nutrient content in pakchoi (Brassica chinensis L.) at different levels of sulphur (in the form of sulphate) supply were studied. The results showed that plant growth was improved by addition of low doses of selenium and inhibited by addition of high doses of selenium at low sulphur concentration. However, the plant growth was inhibited by the application of selenium at high sulphur concentration. Selenium accumulation in pakchoi increased with selenium concentration in culture solution and slightly decreased with increase of sulphur level. At low sulphur level, N, P, K, Ca, Mg, Fe, Mn and B content of the plant were not considerably affected by low doses of selenium and N, K, Fe, Mn and B were reduced by high doses of selenium. At high sulphur level, N, Fe and Mn content were increased by application of selenium. However, The P, K, Ca, Mg and B content were not remarkably affected. The protein content increased and the total free amino acid content decreased following application of selenium at both high and low levels of sulphur. |
