EXPERIMENT STATION REPORT. 505 



It is to be noted that the number .of those heads with yellow 

 centered flowers — the ray blossoms having some other color — is very 

 large, so that all together the yellow color is by far the leading one 

 for the heads that are not yellow throughout. 



At the time (June 14th) when the plants were maturing the 

 seeds, a number of heads, one from a plant, gathered at random, gave 

 the following results, in terms, of good and abortive fruits (seeds) : 



No. Sound. Abortive.

It is noted that the number 93 leads with twelve, while No. 234 (y) 

 comes next, with eight. A striking difference between these two sets 

 is seen in the number of sound and abortive seeds. The 93 gives 

 an average of 42 sound and 17 abortive seeds, while 234 (y) has 11 

 sound and 44 abortive seeds. 



At another time all the heads upon five plants were considered, 

 with the following results : 



Plant 1. No. 93. Six heads Average sound, 20 ; abortive, 41
