Once cutting: 15th, May. 



Twice cuttings: 15th, May; 15th, June. 



Thrice cuttings: 15th, May; 15th, June; 15th, July. 



Four times cuttings : 15th, May ; 15th, June ; 15th, July ; 15th, Sept. 



The seedlings so cut at their root ends at various intervals were 

 left to grow in the same place. The cuttings again were made on the 

 same date, the next year, and the inflorescence were fully studied. The 

 results were as follows, the number of seedlings for each lot was taken 

 as 100:— 



From the above statement, one notes that the inflorescence of Sugi 

 seedlings depends upon the growth of roots and subsequently the nutrition. 

 For example, in rich soil with ample water supply, where roots grow 

 freely, the seedlings use most of the nutriment assimilated for the 

 construction of leaves and stems, and make a luxuriant growth of crowns. 

 On the contary, where nutrition is scanty with but a poor supply of 

 water, the roots develope but poorly and most of the nutrition is used 

 forming flowers and fruits, the plant itself being but poorly developed. 



When seedlings that once bore numerous flowers are planted in 

 other places, they continue to bear numerous flowers for several years in 

 the replanted place. 



2. Surroundings and Inflorescence. 



With the view of studying the effect of the surroundings and soil 

 upon flower bearing, experiments were made at our Station on various plots, 

 (1) Sunny Plot.
