Effects of different amounts of Cassia rotundifolia appended on the yield and amino acid of Tricholoma loba tense heim

Tricholoma loba tense heim was cultured in nutritional matters appended with seven different amounts of Cassia rotundifolia.The results show that the yields of Tricholoma loba tense heim's being appended with different amounts of Cassia rotundifola are higher than that without Cassia rotundifolia,and the difference is obvious at 0.01% level.The regression equation of the Tricholoma loba tense heim' yield and the Cassia rotundifolia's amount is Y=115.9583+2.965X-0.037708X²,and the Tricholoma loba tense heim' yield reaches the maximum when the amount of Cassia rotundifolia is appended to 500g/kg of culture matters.Moreover,the relation between the total quantity of amino acid and the amount of Cassia rotundifolia appended is bally obvious,R² is 0.9589^**.The effects of appending Cassia rotundifolia on three big types of amino acid,i.e.necessary amino acid,sweet taste amino acid and enfant amino acid including eleven kinds of amino acids in the first principal component,are great,and then the total quantity of amino acid is affected.
