PLATE V 



Fig. 9. Reverted wood from a Seabrook's Black 

 grown at Chelmsford. Last year's terminal, situated 

 in the photograph between two lateral growths, 

 was killed by mite and its base whitened to show 

 its position. This year" s extension growth was formed 

 from one of the high lateral buds. 



Fig. 10. Parts of two shoots of Seabrook's Black. 

 In the longer shoot 1. 3, 4 and 5 (reckon from the 

 top) are killed buds of varying size. Lateral no. 2 

 resembles a big bud but is smaller in shape and 

 contains no mites. The terminal is blank, having 

 been completely killed by mite. The smaller shoot 

 is photographed partly end on to show the minute 

 bud formed from one of the accessory growing points 

 originally present in the now killed terminal bud. 

 The shoot also shows "round" buds and "lulled" 

 buds lower down. 



Fig. 11. Reverted wood of Seabrook's Black grown 

 at Chelmsford. The immediate cause in this case 

 was the formation of a flower bud as terminal in the 

 preceding season. The strig of the fruit formed from 

 it can be seen on the left-hand side at the extreme 

 base of the current j'ear's wood. 



Fig. 12. Reverted wood of Seabrook's Black grown 

 at Chelmsford. The strig formed from the flower 

 bud formed as last year's terminal is clearly to be 

 seen at the top of the figure. Nearly all the lateral 

 buds have made abnormal growth.
