Table VI. 



As Table \1 sLows, it is evident that -the time of bloom of the 20 H- 

 pkuts was not accelerated. The growth of 20 H was inferior to that of the 

 controls. The damage by Plpistnllua abramus Isecame manifest in the middle 

 of May, the plants were severely stunted, Imt produced s^eds (see Figs. 9 and 

 10). 



As aforesaid, in the c.ise of the seetls whose water content was a little 

 over 57°^, only 20H-plants amoug the irradiated bore fi'uits, though their 

 remainder was les3, and, moreover, the growth inferior to that of the cjnti-ols. 

 Other iiTadiated plants did not sprout (with the escaption of a few), and 

 oea=ed to grow at almost the same stage. The sprouting of the irradiated 

 seeds was not accelerated, nor the bloom, they were rather delayed. 



Experiment VI. 



The seeds were steeped in water for 34 hours and exposed tj the rays 

 of lOH, 20H, 30H, 40H imd 50H', when the water content reached 63.37% 

 on Oct. 28. 22 hours after iiradiation they were sown in humus ; 20 see<l3 

 of each group of iiTadiated ssed and 40 gi'aius as controls. 



1. Il tojk 15 minites to get 50H.
