Abstract:

Selenium enrichment in Salicornia bigelovii Torr. was achieved by the means of foliage spray of Na2SeO3 solution. The effects of Na2SeO3 concentration, pH adjustment of Na2SeO3 solution and spraying times on the contents of total selenium and organic selenium and the conversion ratio of organic selenium were investigated by single factor test, and the three factors were optimized by response surface analysis (RSA) with the organic selenium content as the indicator. The results showed that the optimal conditions for selenium enrichment were as follows: the Na2SeO3 concentration, 200 mg/L; adjusting the pH of Na2SeO3 solution to 7.3; and spraying the Na2SeO3 solution twice. Under these conditions, the total selenium content, organic selenium content and translation rate were up to 2.58 μg/g, 1.29 μg/g and 50%, respectively.

Key words: Salicornia bigelovii Torr., optimization, selenium enrichment
