Fig. 138. — Correlation between average yield of culm per 

 plant, in decigrams, subject; and average number of 

 kernels per culm of plant, relative 

 r = .928 ± .005 



The correlations between average yield of culm per plant and average 

 number of spikeiets per culm of plant (Figs. 139 to 144) are again so nearly 

 the same in amount that no significance may be placed on the difference. 

 In line 50 the extreme difference is .040 ± .014; in line 62 it is .021 ± .010.
