102 STATE HORTICULTURAL SOCIEIY. 



Of the apples worked upon only two varieties, Fall Pippin and 

 Peter Gideon's Best, were proven to be capable of self-fertilization. 

 The following varieties did not set any fruit where their flowers were 

 sacked, though they set abundantly where their flowers were left ex- 

 posed : Babbitt, Gano, Gill's Beauty, McAfee's Nonesuch, Shackle- 

 ford, Woodmansee, Sharp, Holraan, Ben Davis, Lowell. It remains to 

 be proven by farther experiment whether the failure of these varieties 

 to set fruit in sacks was due to impotency of their own pollen or to 

 the fact that some mechanical difficulty prevented their pollen from 

 reaching their pistils. 



The 110 varieties of grapes, embracing many different types, gave 

 some very interesting results. The following fifty-six varieties form 

 perfect bunches when self-fertilized : Wells, Niagara, Pocklington, 

 Moore's Early, Potter, Hayes, Vergennes, Poughkeepsie Red, Eaton, 

 Empire State, Centennial, Diamond, Highland, Delaware, Early Vic- 

 tor, Standard, Stayman's No. 15, Stayman's No. 18, Stayman's No. 44, 

 Stayman's No. 47, Woodruff Red, Green Mountain, Transparent, New 

 Haven, Mason's Seedling, Israella, Wyland, Lutie, Othella, Norfolk, 

 Northern Muscadine, Herbemont, Catawba, August Giant, Ives, Jeffer- 

 son, Janesville, Lady Washington, Montifoire, Gambridge, Cynthiana, 

 Perkins, Challenge, Mary Ann, Amber, Martha, Elvira, Rochester, Nor- 

 ton's Virginia, Telegraph, Requa, Noah, Rentz, Dracut Amber, Agawan 

 and Etta. 



Some varieties were shown to be barely capable of self-fertiliza- 

 tion. While they set a few fruit in sacks the bunches were very im- 

 perfect, most of the berries failing to set. When left exposed to nat- 

 ural pollination they set much better. This list includes seventeen 

 varieties, as follows : Worden, Jessica, Duchess, Stayman's No. 42, 

 Lady, Bacchus, Wyoming Red, Diana, Conquerer, Hartford Prolific, 

 lona, Missouri Reisling, Pearl, Champion, Cottage, Hermann and Faith. 



The following varieties were fund to be incapable of self-fertiliza- 

 tion, but they set fruit when planted with other varieties : Ideal, Jew- 

 ell, August Giant, Brighton, Moyer, North Carolina, Herbert, Ironclad, 

 Aminia, Jewell, Amber Queen, Lindley, Neosho, Rothwell's Seedling, 

 Black Hawk, Salem, Green's Golden, Black Eagle, Taylor, Bullitt, Mas- 

 sasoit, Barry, Isabella, Eumelon, Wilder, Wilding and Marion. 



The failure of different varieties to self-fertilize may be due to dif- 

 ferent causes. The pollen of some varieties is not self-potent — that is, 

 though it reaches the pistil all right, it is incapable of promoting the 

 setting of the fruit. In some varieties the pollen and the pistils are 

 not ready for fertilization at the same time. The pollen may ripen too 

 early, or, on the other hand, too late to impregnate or fertilize the
