摘要
为探讨硒硫互作对白菜芽苗菜硫代葡萄糖苷(以下简称硫苷)含量及抗氧化性的影响,以白菜种子为实验材料,通过4 mmol/L ZnSO_(4)溶液单独喷施、50μmol/L和100μmol/L的Na_(2)SeO_(3)溶液单独喷施以及二者联合喷施,分析白菜芽苗菜主要生理生化指标、抗氧化能力及硫苷含量等变化规律。结果表明,单独施用ZnSO_(4)溶液对白菜芽苗菜造成了生长胁迫,而单独施用Na_(2)SeO_(3)溶液可增加芽长和单株平均质量;Na_(2)SeO_(3)溶液联合ZnSO_(4)溶液喷施处理可以有效缓解单独施用ZnSO_(4)溶液对白菜芽苗菜生长发育的抑制作用。同时,相较于对照(喷施去离子水),经过ZnSO_(4)溶液联合Na_(2)SeO_(3)溶液喷施处理后,白菜芽苗菜硒元素含量及总硫苷含量均显著提高(P<0.05),其中ZnSO_(4)溶液联合50μmol/L Na_(2)SeO_(3)溶液喷施处理6 d后总硫苷含量增加约50%;总体上发芽6 d的芽苗菜硒元素和硫苷含量明显高于4 d时的芽苗菜。研究结果可为生产富硒高硫苷的功能性白菜芽苗菜提供参考。
In order to explore the effect of selenium-sulfur interaction on the glucosinolate content and antioxidant properties of Chinese cabbage sprouts,the seeds were sprayed with 4 mmol/L ZnSO_(4),50 or 100μmol/L Na_(2)SeO_(3) or their combination during sprouting and the changes in the major physiological and biochemical indexes,antioxidant capacity and glucosinolates content of Chinese cabbage sprouts were analyzed.The results showed that the application of ZnSO_(4) alone caused growth stress on Chinese cabbage sprouts,while the application of Na_(2)SeO_(3) alone increase the length and fresh mass of sprouts per plant.The combined application of Na_(2)SeO_(3) and ZnSO_(4) could effectively alleviate the inhibitory effect of ZnSO_(4) on the growth and development of Chinese cabbage sprouts.Moreover,compared with the control group(deionized water),ZnSO_(4) combined with Na_(2)SeO_(3) significantly increased total selenium content and the contents of total glucosinolates(P<0.05),and the combined application of ZnSO_(4) and 50μmol/L Na_(2)SeO_(3) resulted in an approximate 50%increase in the total content of glucosinolates.The contents of total selenium and total glucosinolates were significantly higher on the sixth day than on the fourth day of sprouting.The results of the study provide data support for the production of functional Chinese cabbage sprouts rich in selenium and glucosinolates.
