BUD VAEIATION IN THE MARSH GEAPEFEUIT. 



101 



However, 42 of them, or 80.8 per cent, are within the comparatively 

 uniform limits between 186.8 and 117.8 pounds. The three lowest 

 producing trees in this plat are of the Unproductive strain. 



Table IV shows the proportions of first-grade fruit in the crops of 

 each tree in the investigational plats during the 6-year period, 1910 

 to 1915, inclusive, and the percentages of variable fruits which were 

 recorded from each tree during the four years, 1912 to 1915, inclusive. 



Table IV. — Average annual production of the individual Marsh grapefruit trees in 

 investigational plats A and B, for which detailed performance records were obtained 

 for the 6-year period, 1910 to 1915, inclusive. 



[The strain to which each tree belongs is shown by abbreviations as follows: AB= Alternate Bearing, M= 

 Marsh, R= Rough, RS= Rough Seedy, SS= Smooth Seedy, U= Unproductive.]
