BENCH-GRAFTING RESISTANT VINES. 233 



30th of December, when the grafts were taken out of the 

 nursery: 



English grafts with scions of two eyes : 180 Zinfandel on 

 Rupestris du Lot. Most of the unions were very well 

 joined. The average length of the shoots was from 1 to 2^- 

 feet ; the wood was mature. The roots were well developed 

 and grew mostly straight down to a depth of 3 feet, the fine 

 rootlets even deeper, 4 or 5 feet ; 83 grafts had made good 

 unions, that is 46 per cent.; eleven grafts showed imperfect 

 unions. 



English grafts with scions of one eye: 180 Zinfandel on 

 Rupestris du Lot. The difference in the development of 

 the grafts with two eyes and with one on the scion was very 

 slightly in favour of the first, and the shoots as well as the 

 roots of the successful grafts looked nearly alike; 51 grafts 

 had developed fine unions, that is 28 per cent. ; twelve grafts 

 made imperfect unions. This experiment shows clearly the 

 advantage of using scions of two eyes for grafting, as 20 per 

 cent, of grafts were lost by using scions with one eye only. 



Champin grafts with scions of two eyes; 180 Zinfandel 

 on Rupestris du Lot. The unions with this method of 

 grafting did not develop so well as those of the English 

 graft, and though the number of passable unions was 116, 

 they were not of so perfect a character as those of the first 

 experiment, and the number of imperfect unions was 

 greater ; the growth of the shoots was short when compared 

 with the parallel experiment with English grafting. The 

 root system of the stock was well developed, the main roots 

 always going down, with the smaller rootlets mostly 

 horizontal. The main roots had an average length of 3 to 

 4 feet, the shoots a length of about 2 feet. There was 64 per 

 cent, of good unions. 



Champin grafts with scions of one eye; 180 Zinfandel on 

 Rupestris du Lot. The unions in this experiment were 

 somewhat inferior to those of the last. A good many roots 

 had formed; all were of smaller diameter than those men- 

 tioned above ; but, like them, going straight down with an 

 average length of 3 feet. The roots were, as a whole, less 

 developed than those of the foregoing experiment. The 

 quality of the unions in this case was decidedly inferior to 

 the parallel experiment with English grafts ; 58 per cent, of 

 the grafts made sufficiently good unions.
