TABLE 15. Average Number of Flowers on Spurs Holding Fruit for Varying 



Lengths of Time 



There seems to be a correlation between the number of flowers on 

 a spur and the abiUty of the spur to hold fruit. Spurs that lose all flowers 

 and fruits during the first drop have the smallest average number of 

 flowers, and those that finally set have the largest average number of 

 flowers. 



Set of fruit on spurs with varying numbers of flowers 



The spurs from several branches were grouped in lots based on the 

 number of flowers borne. The percentage of spurs bearing fruit in each 

 case is recorded in table 16: 



TABLE 16. Set of Fruit on Spurs with Varying Numbers of Flowers 



* After the first drop, 

 t After the June drop. 



These data likewise show that the fruit-bearing ability of a spur is 

 closely related to the number of flowers produced by the spur. The spurs 

 having the greatest numbers of flowers show the highest percentage set. 



Percentage of flowers developing into fruits on spurs producing varying 



numbers of flowers 



In many cases the spurs bear more than one fruit. Do individual 

 flowers on spurs producing sLx blossoms have to compete more for their
