 lemons in the investigational performance-record plat, during the 5-year period from July, 1911, to June,

In conductmg the studies of the seed content of the fruits it vas 

 very noticeable that there was a considerable variation in different 

 months of the year. In order to show this seasonal variation, Table 

 XVIII has been prepared, presenting the average number of seeds 

 found in fruits of the 

 various strains during 

 each month. This 

 table shows a fairly 

 uniform regularity of 

 variation during the 

 different months for 

 the several strains 

 listed, the time of low 

 seed content coming 

 in October, Novem- 

 ber, and December, 

 with a rapid increase 

 from that time till 

 April, May, and June. 

 Figure 17 shows this 

 variation graphically 

 for the four strains 

 that were most fre- 

 quent in the perform- 

 ance-record plat. The 

 other strains and 

 groups shown in 

 Table XVIII conform 

 so closely with the
