. 551] INFLUENCE OF STARVATION 



(i()9 



the diagram also shows at once that* seed weight has not 

 been influenced by the starvation conditions as other 

 characters have. Whereas, with a single exception, num- 

 ber of pods per plant, number of ovules per pod and num- 

 ber of seeds per pod were all conspicuously reduced, seed 

 weight is sometimes higher, sometimes lower, on the 

 starvation plots. Of the 28 differences, 21 are negative 

 in sign, as compared with 28 for pods per plant and 

 ovules per pod and 27 for seeds per pod. 



Expressing numerically the same differences for the 

 ancestral series as are usually taken for the comparison 

 series, we find for comparisons within the strains :

Thus there appears to be a distinct influence of the de- 

 pauperization of the individual upon the weight of the 

 seeds which it produces. But modification of weight is 

 very slight indeed as compared with that of the other 

 characters.
