From the Director . 



Information obtained through 

 research today becomes the founda- 

 tion for better living tomorrow. 

 Present discoveries may have prac- 

 tical application or offer funda- 

 mental information upon which 

 even greater discoveries are based. 

 Many commodities that we take 

 for granted were born in the re- 

 search of yesterday. 



The articles in this issue reflect some of the work carried on by the School 

 of Agriculture and Horticulture in the research program at your state 



university.
