BUD VARIATION IN THE LISBON LEMON. 53 
TaBLE VI.—Average annual crop of the individual lemon trees of several of the important 
strains occurring in the investigational performance-record plat of the Lisbon variety, 
ranked according to the weight of their average total crops. 
[This is a summary of data for the 4-year period from July, 1913, to June, 1917, inclusive, except that the 
data for the trees of the Bull strain and three other trees, as indicated in Table I, cover only the 3-year 
period from July, 1914, to June, 1917, inclusive.]

Vic. 5.—Diagram showing the percentage of variable fruits of the Lisbon lemon occurring on the trees of 
the different strains in the investigational performance-record plat during the 4-year period from July, 
1913, to June, 1917, inclusive. The data for the trees ofthe Bullstrain and three other trees, as indicated 
in Table I, cover only three years. The proportions are based on the number of fruits produced. 
TaBLe VII.—Production of fruit of the three different grades and of variable fruits picked 
_ from the lemon trees of the several strains of the Lisbon variety in the investigational per- 
Jormance-record plat during the-4-year period from July, 1913, to June, 1917, inclusive. 
[The strains are ranked according to their proportion (by weight) of fruit of the Green grade.]
