Nobbe obtained siniilar results with other seeds, for example, 

 Brassica Rapa var. biennis. 



The experience of the Copenhagen Seed Testing Station as reported 

 by the Director (i) leads to the same general conclusion, namely, that 

 ripe seeds retain their germinating capacity longer than seeds which 

 are less ripe. 



The complication introduced by the harmful secondary effect of 

 dry storage upon immature seeds must have entered into such experi- 

 ments as those carried out by Lucanus. Lucanus(i7) conducted a very 

 elaborate series of experiments with rye, harvesting his seed at five 

 different stages of maturity and dividing each harvest into four 

 divisions, viz. : 



Seeds immediately removed from the head (Section I of Table VI). 



Seeds dried in the ear (Section II of Table VI). 



Seeds dried in the ear on the stalk (Section III of Table VI). 



Seeds dried in organic connection with the entire plant, the roots 

 of which were placed in distilled water (Section IV of Table VI). 



The results (Table VI) showed that in garden soil rich in humus the 

 various stages of maturity of the seed had little or no effect upon the yield 

 per plant as shown in his table, but a better total yield was obtained from 



Table VI.

60 seeds sown in each experiment.
