PLATE VI 



Fig. 13. Reverted wood of "French" grown at 

 Long Ashton. The strig from last year's terminal 

 flower bud can be clearly seen. The two accessory 

 growing points originally present in the terminal 

 flower bud have in this case both grown, giving the 

 appearance of a divided terminal. Big Bud is pre- 

 sent but was not the cause of reversion. 



Fig. 14. Growth resulting from aphis check in 

 summer. Specimen from Long Ashton. At the top 

 is the original terminal much weakened by aphis 

 attack. The strength of the shoot, in this case a 

 strong sucker, was thrown almost entirely into the 

 five buds immediately below.
