DIEMBRYONY IN CORN 



By Byron D. Halsted 



In making some germination tests of corn upon a large scale 

 a single grain was met with that showed a double embryo — one 

 n apparently normal and the other sec- 

 ondary. The grain in germination 

 was lying with the embryo side down- 

 ward so that the main plantlet needed 

 to turn upward around one side of the 

 grain making a J-shaped curve. The 

 smaller shoot grew nearly parallel 

 with the first one and stood close 

 to it, although much smaller. The 

 grain was transferred from the germ- 

 inating dish to earth in a flower pot 

 and supplied with conditions for fur- 

 ther growth, at which time each plant- 

 let had a main root. 



Aff.er'growing as long as the smaller 

 plant would, the two were removed and 

 a photograph taken from which the 

 little side engraving has been made. 



It is seen that one plant grew quite 

 normally, while the other remained 

 small and attempted to produce two 

 ears, but without tassel, and no grains 

 were obtained. 



It only needs to be said that the 

 case in hand was a yellow grain from 

 an ear picked upon the College Farm 

 and brought to me, because it was the 

 only one of a large field that had dark, 

 nearly cherry-colored grains mixed in almost equal numbers with
