Bulletin 71, 



We frequently lose trees on peach roots without any visible 

 break at the union; but an examination under the bark will 

 usually show a line of separation between the peach and apricot. 

 Fig. I shows the union of a Moorpark apricot, which m5'Ster- 

 iously yellowed and died. When split open, the union presented 

 the appearance shown in Fig. 2, in which it will be seen that the 

 peach and the apricot had broken apart, in the direction aa. 

 The break is particularly apparent in the left-hand section. This 

 tree had been girdled from the breaking away of the cion and 

 stock. 



SiDiie jDiion as Fig. /, split lengthwise and showing the divorce oj 



cion and stock. 



Myrobalan stocks have behaved no better with us. Fig. 3 

 shows how a Harris apricot tree broke off the mjTobalan root 

 with a clean and smooth fracture, showing that there was no real 

 affinity between the two. 



E. Smith & Sons, whose apricot orchard on Seneca Lake is the 

 largest in the state, tell me that they have had trees break when 

 nursery-budded upon peach and plum ; but apricots on apricot 

 roots have never broken, although such trees have died more 

 freely than any other, a circumstance which is probably to be 

 attributed to uncongenial, hard soil.
