GRAPE PRUNING AND TRAIiXING 



303 



others remaining latent (55). If the vine is pruned so 

 as to leave only 50 to 75 buds therefore, the result will 

 probably be the same number of shoots, though doubt- 

 less from a somewhat different set of buds, because the 

 buds near the bases of the shoots rather than those nearer 

 the terminals will grow (55). Neither the quantit}' nor 

 the (juality of the crop nor the \igor of the vine or its 

 shoots will show any conspicuous difference. 



Should the vine be pruned more severely, leaving only 

 25 or 30 buds, the number of shoots will, of course, be 

 smaller. Hence the supply of stored food in root, trunk 

 and branches and the supplv of crude sap from the un- 

 pruned roots will he distributed in larger quantities to the 

 shoots, which will thus grow more \igorously than they 

 would were there more of them. This smaller number 

 of large shoots will jiroduee fully as great an area of leaf 

 surface as would the greater number of smaller shoots 

 on the unpruned vine, so the ^'iGor of tht' vine will in no 

 way be impaired by the reduction in number. Similarly, 

 a smaller num1)er, but larger-sized bunches and berries, 

 will be produced by the smaller number of large shoots; 

 so the total weight of the crop will be at least as great as 

 when the greater number of clusters and berries are 

 borne on the smaller but more numerous shoots. Indeed, 

 e.xperienee pro\'es that sizx" of both berry and cluster is 

 larger and weight of crop greater on pruned than on un-
