The variations in seed content in the several Lisbon strains from 
month to month throughout the year are presented in Table X1IT 
and the data for the Open, Lisbon, and Dense-Unproductive strains 
are shown graphically in figure 11. The irregularities for November

Fig. 11.—Diagram showing the average number of seeds per fruit of some of the strains of the Lisbon 
lemon found ¢ach month on trees in the investigational performance-record plat during the 3-year 
period from July, 1913, to June, 1916, inclusive. 
and April are probably accounted for by the fact that owing to 
interference of one sort or another records are available for only 
two seasons in November and for one season in April. The periods 
of lightest and heaviest crop production are known to vary somewhat 
from year to year, as already shown, and it is believed that in the 
same manner the seasons of high and low seed content fluctuate in 
different years. Hence, with records for only two years for Novem- 
ber and one year for April, while the other months are represented 
by data for three years, it is quite probable that the me lptLo variations 
as Shown are somewhat incorrect.
