INFLUENCE OF POLLED. 121 



Since the attention of horticulturists has been called 

 to this subject, several who combine science with prac- 

 tice have repeated my earlier experiments with the 

 Strawberry, and in a majority of instances with like 

 results. Prof. W. R. Lazenby, of the Ohio Experiment 

 Station, made several very carefully-conducted experi- 

 ments with different varieties of the Strawberry in 1884, 

 the results of which were fully reported in the Bulletin 

 of the Station for that year. In referring to these experi- 

 ments at the meeting of the American Pomological 

 Society in 1885, Prof. Lazenby stated that he employed 

 a pistillate variety of the Strawberry, known as 

 the Crescent. "Boxes open above and below, and 

 cohered with whitewashed glass, were placed over the 

 plants to prevent accidental fertilization of the flowers 

 by insects or otherwise." The results in brief were : 

 The Charles Downing pollen communicated its .char- 

 acteristic shape, texture, and other qualities, and the 

 same with Sharpless and Vick, so that any one familiar 

 with the berries could tell by looking at the crop from 

 what source the pollen came. The following season, 

 or in 1885, Prof. Lazenby repeated the experiment, 

 but with far less satisfactory results, showing, as I have 

 said, that the irifluence^f the pollen is not always suffi- 

 ciently powerful to change size, color, etc., or it may be 

 said that the influence of the female plant is strong 

 ejiougli to Qverjjalance^and partly suppress that of the 

 niale. 



Prof. Julius Sachs, in his recent great work, " Text 

 Book of Botany, " says, p. 495 : " The increase in size of 

 the ovary, which is frequently enormous (in Curcubitm,\ 

 Cocos, etc., several thousand times in volume), shows, in a 

 striking manner, the results of fertilization * * * to 

 the rest of the plant. Frequently similar changes result 

 also in other parts. Thus, it is the. receptacle that T con-
