28 NEW METHODS OF GRAFTING AND BUDDING. 



MEANS OF INCREASING THE STRIKE OF 

 HERBACEOUS GRAFTS.* 



BY CH. TALLAVIGNES, 



Director of the School of Agriculture, Glides. 



In a series of articles published in the Revue de Viticulture 

 of 1894 we described the principal herbaceous grafts of the 

 vine. Since that time we have pursued our studies at the 

 Agricultural School, Ondes, with the object of ascertaining 

 the causes influenciog the strike of herbaceous grafts. We 

 now intend giving the results of experiments made by 

 Clarac, the manager of the school. 



1st. Herbaceous Graf ting . Selection of shoots bearing buds 

 best fitted for scions. Among all the shoots growing on a 

 vine stump some are better suited than others to furnish 

 scion-buds. We should always choose branches growing 

 from eyes which would have normally remained dormant 

 till the following year, in preference to branches growing 

 from buds bursting normally. Shoots of medium or rather 

 small diameter are to be preferred. These shoots will furnish 

 the scion-buds, which are to be grafted on to the old wood. 

 The diameter of the shoots from which the scion-buds are 

 excised must always be less than those upon which it is to 

 be grafted. The best shoot to use is that developed in the 

 shade, that is to say, sheltered by other shoots. Branches 

 exposed to direct sunlight must always be rejected. The 

 colour of the shoot is also of certain importance ; it should 

 be light green, but not yellow. 



The petioles of the leaves of the shoot should be of a 

 whitish green, even a little pinkish, slightly transparent at 

 the point of junction with the limb. Shoots bearing leaves 

 with deep green, or red petioles, and non-transparent, must 

 be rejected. The eyes of the extremity and base of the shoot, 

 together with those placed at the base of leaves having a 

 petiole too slender or too long, should not be used.
