Fig. 16.— Diagram showing the average number of seeds per fruit on trees of the various strains of Eureka 
lemons in the investigational performance-record plat, during the 5-year period from July, 1911, to June, 
1916, inclusive. 
In conducting the studies of the seed content of the fruits it was 
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 
curves shown in figure 17 that it was impracticable to represent all 
of them clearly in this diagram. A comparison of figures 16 and 17
