Texas Station, Bulletin No. 15, May, 1891 (pp. 16). 



Influence of climate on composition of corn plants, H. H. 

 Harrington, M. S. (pp. 77-86). — This experiment was made with a view 

 to determining- the variation in the composition of the same varieties of 

 corn when grown in different sections of the country. The plan of the 

 experiment originated Avith the Texas Station. Seed corn raised in 

 Wisconsin, 'New York, Maryland, Kansas, Kentucky, Texas, and Geor- 

 gia, one variety from each State, was sent to the stations in Mississippi, 

 Maryland, Georgia, Connecticnt, New York, Wisconsin, and Kansas in 

 the spring- of 1890, for planting-. Analyses were to be made by the 

 Texas and the Connecticut State Stations of the seed corn used and 

 the crop secured in each of the States, For various reasons reports 

 were only received from Connecticut, New York, and Georgia. The 7 

 varieties of corn grown in New York and Georgia and 2 grown in 

 Connecticut were analyzed by the Texas and Connecticut State Stations, 

 and the residts are reported in the bulletin. Considerable discrepancies 

 are noticeable between these two sets of analyses. Only the analyses 

 by the Texas Station Avill be considered here. 



The corn raised in New York from seed grown in Kentucky, Mary- 

 laud, and Texas was lower both in protein and fat than the seed fr-om 

 which it came, and that grown from Wisconsin, Kansas, and Georgia 

 seed showed a slight increase in protein but a decline in fat. The corn 

 raised in Georgia from seed grown in New York, Kansas, and Kentucky 

 was lower than the seed corn in both protein and fat, and that fr'om 

 Wisconsin seed was slightly richer than the seed in both these constitu- 

 ents. No wider differences were presented than those between com 

 raised from the same variety of Northern-grown seed in Connecticut 

 and New York, as will be seen from the following example:

The corn grown in Georg-ia from Georgia seed likewise showed 

 considerable variations in composition from the seed. It is obviously 

 impossible to make any general deductions as to the influence of locality 

 on the composition from the data at hand.
