 of bevelled. 



GREEN-GRAFTING is a comparatively modern process 

 which is commonly practised in Hungary and to some 

 extent also in Italy. Of course its application for the 

 propagation of the vine on a large scale is hardly 

 admissible, but it is recommendable in certain cases, viz : 

 (i) To fill up gaps in the vineyard by layering, when on 

 a cane of the nearest vine is inserted a scion of an 

 American vine, and as soon as the scion has grown to 

 the desired length for layering, is in its turn grafted with 

 a scion of the same European vine on which it is grow- 

 ing, and thus the cane which will be layered in autumn 

 or winter will have the interred part formed of American 

 wood and therefore resistant to" Phylloxera. (2) To 

 obtain grafted cuttings which may be planted directly in 

 the vineyard, or grown as grafted plants in the nursery. 

 In this case the canes of an American vine having 

 reached the necessary length to make a good cutting are 

 grafted with scions taken from the European vine which 

 it is desired to propagate. The grafted canes are then 

 used as cuttings, the interred part being made of 

 American stock, and are disbudded as in the case of 

 ordinary grafted cuttings. (3) To graft the young 

 growing shoots which are thrown up by a cane which has 

 been layered according to the so-called Chinese method. 

 In this case the grafted shoots can be used as rooted 

 and grafted plants for direct planting in the vineyard, in 

 the following autumn. (4) To propagate a rare sort of 

 which it may not be possible to obtain scions for autumn 

 or winter grafting. (5) To graft a vine on a pergola or wall, 

 with various sorts of grapes, as an object of curiosity. 



The best time lor green grafting is from April to 

 the end of July; towards the middle of April the weather 

 is usually already warm enough to insure success and in
