BUD VARIATION IN THE EUREKA LEMON. 



29 



the complote records of all of the trees in this bulletin; hence, it has 

 been necessary to select a num])or of trees for this purpose. Tables 

 VIII and X give the detailed performance records of 24 representa- 

 tive lemon trees of the 117 in the investigational plat of tlie Eureka 

 variety. This list includes examples of all the strains found in the 

 plat and was made by arbitrarily selecting every eighth tree of the 

 Eureka strain as listed in Table VI, every fifth tree of the Shade-Tree 

 strain, every fourth tree of the Small-Open and Dense-Unproductive 

 strains, and both trees of the Dense-Productive and Pear-Shape 

 strains. In each case the highest and lowest ranking trees of each 

 strain are included. This basis was adopted in order to remove aU 

 chance of any personal bias in the selection of the trees and is thought 

 to include more representative trees than the basis employed for this 

 purpose in earUer bulletins of this series. Tables VIII and X are 

 thus made to include 10 trees of the Eureka strain, 4 of the Shade-Tree 

 strain, 3 each of the Small-Open and Dense-Unproductive strains, 

 and 2 each of the Dense-Productive and Pear-Shape strains. 



Table VII. — Distribution of lemon trees of the Eureka variety in the investigational per- 

 formance-record plat, shoiuing also the strain and the rayih in crop production of each 

 individual tree for the 6-year period from July, 1911, to June, 1917, inclusive., 



[The positions of the trees in ranks 07, 69, 90, 90, 97, 101, 106, 107, 109, 115, 116, and 117 are not here indicated. 

 As shov.-n by their location numbers in Table VI, they were situated at varying distances outside the 

 main body of the plat, and it was thought inadvisable to include them in this table. This orchard is 

 planted on the contour and on that account the trees in rows across it do not bear the same niunber, 

 counting from the southern end, which is taken as the head of the row. The trees in rows 74 and 75 are 

 numbered one in advance of the nearest one in row 73, and those in rows 70 and 77 are two in advance of 

 those in row 7:5, as indicated. Explanation of symbols: 0= Eureka strain, A= Shade-Tree strain, [3= 

 D'ense-Productive strain, n= Dense -Unproductive strain, ©= Pear-Shape strain, ^= Small-Open 

 strain, X = not included in the record.]
