THE HOP PLANT. 31 



It is thus clear that by means of this method the founda- 

 tion of new varieties can be laid, the subsequent reproduction 

 of which by cuttings will be free from difficulty. 



Noteworthy results have been obtained by E. Zelinka, 

 manager of Count Kleinmichel's hop gardens, who, by 

 selection and without sexual reproduction, obtained from 

 root cuttings of special hop plants two new varieties, one

characterised by early ripening and the other by particular 

 fruitfulness.^ 



In practice the hop is propagated solely by cuttings from 

 the roots, or rather from portions of the stem remaining in 

 the ground after vegetation has ceased for the year (Fig.
