 spikelets per culm of plant, relative 



r = .892 ± .008 



In the correlation between average yield of culm per plant and average 

 weight of kernels per plant (Figs. 145 to 150), there is in line 50 a graduated 

 increase with increased crowding. For series -63 the coefficient is .492 ± 

 .033, while for series 122 it is .652 zh .022 — an extreme difference of 

 .160 ± .040, which, however, amounts to but four times its probable
