JUICE OF MUSA 13ASJOO IN WINTER. 



401 



careful examinations proved that neither asparagin, nor tyrosin, 

 nor leucin, were present. Hence in the period of rest, no decom- 

 position of protein takes place in the juice of the plant. 



It is, however, of some interest that in the absence of aspara- 

 gin the closely related succinic acid is present. 



The juice of the pseudotrunk of Musa contained therefore : 



Total dry matter —0.927% 



Succinic acid 0.18 % 



Sugar 0.03 



Nitrogenous extract — 0.44 



Ash 0.27 



Oxidase and Peroxidase.
