20. EFFECT OF ANEURINE ON HIGHER PLANTS 



The pronounced stimulating effect of aneurine on micro-organisms 

 suggested that it might be a growth factor for higher plants, and 

 possibly even a plant hormone, biologically similar to auxin. Expec- 

 tations of this type, however, have not been realised, for in no plant
