Effects of different amino acid treatments on the growth and quality of broccoli sprouts
In order to explore the effects of different amino acids on the growth and quality characteristics of broccoli sprouts.In this study,six amino acids(glycine,tryptophan,phenylalanine,methionine,tyrosine and glutamic acid)were applied to the roots of broccoli sprouts to improve the growth index(sprout length and moisture content)and quality index(soluble sugar,soluble protein,total flavonoids,total phenols,nitrate nitrogen,light and pigment,total glucosinolate and sulforaphane)of the treated broccoli sprouts.The results showed that different amino acid treatments increased the soluble sug-ar,soluble protein,total flavonoids,chlorophyll a,chlorophyll b and carotenoids content,significantly decreased the nitrate content,and inhibited the accumulation of total glucosinolates.Among them,the soluble sugar content(650.64 mg·g-1)and sulforaphane content(904.17 μg·g-1)in broccoli sprouts after methionine treatment significantly increased the most,and increased significantly 28.42%and 123.71%,respectively,compared with CK.The research results can provide the-oretical basis for the application of amino acid treatment in the production of broccoli sprouts.
