MASS. EXPERIMENT STATION BULLETIN 190. 



At the outset of this work a number of grafts on the common French 

 pear and on sand pear roots were made in addition to those on standard 

 apple roots and some on English Paradise. It was thought that inasmuch 

 as the pear roots would make but a poor growth, a greater number might 

 root from the scion. Table 9 shows the number of grafts planted and the 

 per cent growing in July following the planting. The grafts on both 

 sand pear and French pear gave much poorer stands than those on stand- 

 ard or Paradise apple roots. Many of them perished before the time 

 of digging at the end of the second summer, so that the records of the 

 number rooting from the scion are too few and fragmentary to be worth 

 presenting. The indications are that on both of the pear roots more 

 trees rooted and had a stronger root system than on apple roots, but so 

 few grafts grew that pear roots are not desirable for propagating apple 

 trees on their own roots.
