不同硒源处理对竹荪子实体营养成分的影响

Differentiation of Nutrient Composition in A Selenium-Sources-Add Treatments of Dictyophora echinovolvata

研究通过对比不同硒源处理中竹荪Dictyophora echinovolvata硒子实体营养成分含量差异,探讨不同硒源对竹荪子实体中营养成分含量的影响。试验设置纳米硒、富硒氨基酸液肥、螯合硒3种硒源,每种硒源选择5、10 mg/L 2种施用浓度。结果表明:施用5 mg/L的富硒氨基酸液肥利于促进竹荪子实体中蛋白质的合成,施用5 mg/L的富硒氨基酸液肥、10 mg/L螯合硒利于竹荪子实体中粗多糖的合成,施用10 mg/L纳米硒利于竹荪子实体中硒元素的吸收存储,施用10 mg/L的螯合硒和纳米硒竹荪子实体中氨基酸总量较大,施用5 mg/L纳米硒可以有效提高竹荪子实体中风味氨基酸占氨基酸总量的比例,施用10 mg/L螯合硒、5 mg/L纳米硒后可以有效提高竹荪的抗氧化功能。

To compared the influence of different selenium source treatments on nutritional composition in fruiting body of Dictyophora echinovolvata,the affect of nutrient composition of D.echinovolvata with different selenium sources was explored.Nano selenium,selenium-enriched fertilizer with amino acid and chelated selenium were chosen,and 5,10 mg/L of each selenium source were designed.The results showed that applying 5 mg/L selenium-enriched fertilizer with amino acid would promote the synthesis of protein in fruiting body of D.echinovolvata.Applying 5 mg/L selenium-enriched fertilizer with amino acid and 10 mg/L chelated selenium would promote the synthesis of coarse polysaccharide.Applying 10 mg/L nano selenium would conducive to the absorb and store of selenium.The total amount of amino acids applied with 10 mg/L nano selenium and chelated selenium was the largest.The content of flavoured amino acids in fruiting body of D.echinovolvata was increased by applying 5 mg/L chelated selenium.The application of 5 mg/L nano selenium or 10 mg/L chelated selenium could effectively improve the antioxidant function of D.echinovolvata.This study might be helpful to provide a useful reference for cultivate to selenium-enriched and selenium choosen of D.echinovolvata.
