 Stock Dept. Rept. 1918-19: 16-19. 1919. — Administrative report of work among fruit growers

1785. Webber, Herbert John. Selection of stocks in citrus propagation. California 

 Agric. Exp. Sta. Bull. 317: 269-301. 1920.— The influence of the character of the stock on the 

 variation in yield of trees, forms the basis of the bulletin, although other important factors 

 are considered. Differences in size of nursery trees of transplanting age is largely due to 

 the fact that the seedling root-stocks on which the trees are budded are of different types, 

 possessing inherent characters that react differently on the growing buds. Recommends that 

 all small seedlings in the seed bed and nursery, regardless of what has caused their dwarfness, 

 be discarded. — A. R. C. Haas.

1787. Whitehouse, W. E. Cold storage for Iowa apples. (Third progress report.) Iowa 

 Agric. Exp. Sta. Bull. 192. 181-216. U fig. 1919.— Methods of control of disease of cold 

 stored apples are set forth. A study was also made of the factors relating to the control of 

 common diseases of the apple in cold storage, such as temperature, humidity, maturity of 

 fruit, size of apples, wrapping paper used in packing and rate of cooling. — Florence Willey. 



1788. Woglum, R. S. Is it safe to fumigate while trees are in bloom? California Citro- 

 graph 5: 190. Fig. 1. 1920.— Experiments show that citrus blossoms and blossom buds are 

 more resistant to hydrocyanic acid gas than tender leaves and shoots. It is suggested that 

 this may be due to higher concentration of reducing sugars in the former. Ordinary fumiga- 

 tion if carefully done will not injure the bloom. — J. E. Coil. 



1789. Young, Floyd D. Rate of increase in temperature with altitude during frosty Dights 

 In orange groves in southern California. California Citrograph 5: 136, 160. 8 fig. 1920.
