THE PROBLEM OF GRAPE POLLINATION 



In many vinevards a poor crop of grapes is obtained, because the flowers 

 are' not properly pollinated. Many varieties are self-sterile, and 

 must be pollinated with pollen from the flowers of some other 

 variety; if there is no other variety bearing potent pollen near at 

 hand, this does not take place, and the crop is a failure, as graph- 

 ically shown in these two photographs. The one above shows a 

 bunch of Brighton, a self-sterile variety, which has been pollinated 

 onlv from its own pollen: on the opposite page is a bunch of Brighton 

 cross-pollinated from another varietv. Photographs from U. P.
