A study of variation in apples, J. K. Shaw (Massachusetts 8ta. Bui. 149 

 (1914), pp. 21-36, fig. 1). — In continuation of previous reports (E. S. R., 26, 

 p. 45) the results are given of a statistical study of the variation in number, size, 

 and form of the apples borne during a period of six years on several Ben Davis 

 and Baldwin apple trees growing in the station orchard. The influences causing 

 such variations are also considered. 



Summarizing the data as a whole, it appears that the Ben Davis trees have 

 borne much more heavily than the Baldwins and have shown hardly any ten- 

 dency to biennial bearing. Relative to tree Individuality the most prolific of 

 five Ben Davis trees yielded over 60 per cent more apples in the total for six 

 crops than the least prolific. The Baldwins have shown even greater differences. 



The upper south quarters of the Ben Davis trees have borne a few more apples 

 than any of the other three quarters, and these apples were constantly larger 

 than those from the other parts, while those from the opposite quarters were 

 generally smaller. Some Ben Davis trees showed a fairly constant tendency to 

 produce apples larger or smaller than the average, whereas others fluctuated 

 from season to season. Only one crop of apples was sufl3ciently heavy in num- 

 bers to affect the size of the fruit. Some slight indications of a relationship be- 

 tween size and the average summer temperature were observed, but the fluctua- 

 tions in temperature were not considered large enough to overcome other in- 

 fluences affecting size. Certain trees showed slight individuality in the amount 

 of variability — the larger the apples the more variable the fruit. This was not 

 true as between the different parts of the trees. 



Some trees were quite constant as to form of fruit, while others were varia- 

 ble. There is no strong evidence that individuality in size and form is to be 

 found in the same tree. Apples from the upper south parts of the trees which 

 were largest were also constantly the most flattened. A fairly constant relation- 

 ship was observed between the form of the apple and the temperature for a 

 period following bloom. The cooler this period the more elongated the apple. 

 In general the period from the sixth to the sixteenth day following full bloom 

 coincides with the observed fluctuation in form more closely than any other.
