46. Radish, Early Scarlet Globe. — Henderson. 



100 seeds in seed-pans, yi inch deep in sand, selected by hand.* 

 No. I, heavy seeds, (average weight 2.53 grains). 

 No. 2, light seeds, (average weight .13 grains). 



SOWN APR 26. 



Epitome. — Sprouting was higher and quicker in the heavy .seeds. 



Figure 5, from a photograph, ilhistrates another test with radi.sh 

 .seeds, in whicli the differences were more marked than in the 

 above instance.

It is often true that over-ripe .seeds germinate more slowly, and 

 give lower total results than others, and this over-ripeness is some- 

 times indicated by additional weight. It is to be expected, there- 

 fore, that in some instances best results in germination come from 

 the seeds of lighter weight. Po.ssibly the two following tests are 

 instances in point ; 



47. Bean, Improved Green Flageolet. — Department of Agricul- 

 ture. 



25 selected white beans in seed-pans, % inch deep in sand. 

 No. I, heavy seeds, (6.25 grains). 

 No. 2, light seeds, (2 grains). 



* In selecting the samples, it is advisable to choose only such seeds as re- 

 present nearly the extremes of weight. By thus discarding the intermedi- 

 ate weights, the results become more marked, and give more accurate 

 measures of the relative values of heavy and light seeds.
