On the Behaviour of Active Albumin as Reserve Material 

 during Winter and Spring 



BY 



U. Suzuki, Noga!iHshi. 



The well known fact that during winter time, much reserve 

 material is stored up in the bark of trees, induced me to make 

 the following investigation, in order to decide whether active 

 albumin is also stored up in the bark of various plants, and 

 whether it is consumed during the development of leaf-buds and 

 flower-buds. Daihihard^^ three years ago, examined many 

 plants, late in autumn and found that the leaves of such plants 

 as contain active albumin during summer time, contain it also late 

 in autumn (October and November) although generally in a far 

 smaller quantity. 



I examined .however the bark and buds in March before 

 the buds had opened. 



In regard to the reactions, I mention more in detail those 

 observed with the bark oi Acscuhis turbhiata. 



Fresh sections of the bark of very young branches were trcat-
