During iheir observations the writers found that the quantity of grape 

 produced increased up to the 6th year of life of the hybrid, and then remain- 

 ed more or less constant. 



By resorting to grafting for hybrids also, their length of life is increased 

 and the range of adaptivity and utilisation of the different varieties of hy- 

 brids is very much extended. The question, however, of affinity of the direct 

 bearing hybrids with the principal grafting hosts is not very well known as 

 3-et. Save for a few exceptions, hybrids are generally good scions, espe- 

 cially for hosts of Vinifera strain (Franco- American) , especially on the various 

 Rupestris X Vinifera.
