BUD VARIATION IN THE EUREKA LEMON. 



69 



Table XIII. — Acemqe, yields and prrrrvtru/rs of total yield of fruit of the Green and 

 Tree-7iipe grades picked each month from the lemon trees of the various strains of the 

 Eureka variety in the investigational performance-record plat during the -i-year period 

 from July, 1914, to June, 1917, inclusive. 

 [The strains are listed in the order of their total-production rank for six years, as showji in Table X.]

1 The season percentage is calculated on the production for the four months, May to August, inclusive . 



In Table XIII and in figures 12, 13, and 14 are shown some of the 

 recorded differences in season of production of fruits of the Green and 

 Tree-Ripe grades by the Eureka lemon trees of the various strains. 

 On account of the interruption to regular picking which resulted from 

 the freeze in January, 1913, only the three years from July, 1914,
