Fig. 12. Fruits of above each lot. In two figures, the coinciding number of lOH-pIants 

 ami fruit are the number of individuals in the fitld. 



Fig. 13. Tlie state fat the time of crop) of plants grown from air-dried seeds of '• Hyogo," 

 ■whose water content was 13.75%, were irradiated on Oct. 28, '17, and, on the nest d.iy sown. 22 

 hours after irradiation, in the field of our institute. Photographed on June 22, '18. 



Fig. 14. Fruits of above each lot. In two figures, same number in different lots, e. g.. No. 8 

 13 in 40 H- and 60H-fruit» and No. 4 is in 60 H- and 80H-fruits, but these are simply the number 

 of individuals in the field. Fig, 14. represents the fruits of each lot in Fig. 13. 



Fig. 15. Shows the seeds of each lot. The numerical number of each lot is that of indivi- 

 duals in the field and common to three figures (Figs. 13-15). 



Fig. 16. The whole crop of each lot of Experiment VII, and one pile is the crop from 

 one plant. It can be seen that the amount of crop decreases proportionally to the increase of 

 dosis given, and that of the 80H is extraordinary small. 



Fig. 17, Seedlings grown from the seeds of " Hyogo " which were steeped for 77 hours (when 

 the water content reached 57.87%) and irradiated on April 19, 1919. On that evening they 

 ■were sown in sands a few hours after irradiation. Photographed in the forenoon of April 27. 

 The lower row represents those from peeled seeds. (Experiment VIH). 



The irradiated seeds are almost in the same stage of growth and no difference in growth is 

 seen proportional to the doses given. 



Fig. 18. Seedlings grown from the air-dried seeds of " Hyogo," water contents of 10.49%, 

 irradiated on June 25, 1919 and sown in sand. Photographed on June 30. 



No sign of accelerjvtion of germination can be seen (Experiment IX).
