300 Plums and Plum Culture 



good fruit. The practical horticulturist is bound to 

 take this view early into account when selecting pol- 

 lenizers for his orchard. This, of course, involves the 

 whole question of the selection of varieties, which can- 

 not be taken up here, but which is discussed in another 

 chapter. But this matter, with the others foregoing, 

 has been taken into account in making up the recom- 

 mendations set forth in the subjoined table of 

 pollenizers. 



Specific recommendations. — All these various mat- 

 ters discussed above, — blossoming season, affinity, 

 amount of pollen, and value of the pollenizer as a fruit 

 bearer, — have to be taken into account at once in se- 

 lecting varieties for cross-pollination. It is somewhat 

 difficult to give these each its proper relative weight in 

 making a selection. The careful and studious plum 

 grower will naturally acquaint himself with these con- 

 ditions, and will thus be able eventually to decide such 

 questions for himself better than anyone can decide 

 them for him. It is for his benefit that so much atten- 

 tion is given in this chapter to explaining the various 

 fundamental principles involved. But the beginner 

 will do better to rely on the judgment of men who are 

 acquainted with the varieties in hand. With this 

 thought in mind, the writer, with the help of Mr. J. W. 

 Kerr, has prepared a tabular list of pollenizers which 

 may be recommended for all the principal native and 

 Japanese varieties. Concerning the Domesticas, a 

 word will be said later. This table, which follows, is 

 republished from the twelfth annual report of the 

 Vermont Experiment station.
