DITISIOX OF HORTICULTURE 627 



SESSIONAL PAPER No. 16 



To summarize the full bloom portion of tlie foregoing table it is found that all 

 the varieties on the average came into full bloom within a period of five days. Tliis 

 is not as much difference as might be expected between early and late varieties, but 

 still a difference of sxifficient importance, perhaps, to prevent some of the earlier 

 varieties from being appreciably pollinated by some of the later ones. 



Following are three lists, giving those varieties which bloom on the same date in 



separate groups: —

PRACTICAL APPLICATIOX OF THE FOREGOING. 



Until some concrete evidence is available regarding the sterility of all the different 

 commercial varieties and the affinity of those varieties for one another, it would 

 appear (1) that it is a wise policy or precaution for orchardists to plant a num- 

 ber of varieties in the same area, rather than to separate the varieties into different 

 blocks; (2) that it is advisable to plant those varieties near each other which ,bloom 

 oh the same day. Thus a prospective planter could, in laying out his orchard, plant 

 the varieties from Group No. 1 close to each other, those from Group No. 2 in another 

 block close to each other and so on. In this way, a precaution against the loss of 

 crop due to sterility could easily be taken. 



A FEW NEW OR NOT WELL-KNOWN VAEIETIES OF FRUITS. 



PLUMS. 



As numerous communications are received requesting information on the varieties 

 of plums adapted to northern and colder districts, a few notes calling attention to the 

 best of the hardy varieties should not be amiss. 



The hardy plums that may be recommended for the colder parts of Canada 

 divide themselves into three groups, viz., the Americana, the Nigra and the Hybrids.
