BUD VARIATION . IN" THE MARSH GRAPEFRUIT. 
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.]
