THE WHEAT PLANT 



In order to determine the variation which can be induced in this 

 manner several wheats were sown at weekly intervals throughout the 

 year ; in the following tables are given the results obtained with an early 

 and one or two later forms sown in the first week of each month : 



RED FIFE 



* Ears were produced in July and August, but these did not ripen in 1912, the summer 

 months in that year being dull and wet. 



t Ears were produced in August and September 1913, but did not ripen : the same 

 plants lived through the winter and produced ears again in 1914. 



This form may come into ear as early as May 19 or not until September 10, and may 

 ripen its ear as early as August 8 or not until September 18. Ears which did not escape 

 from the sheaths before July 10 had not time to ripen in that season and died off.
