HORTICULTURE. 



Notes on self-pollination of the grape, S. A. Beach {Xeic Yuri- 

 tState iSta. Kpt. lti'J2, pp. 507-606). — Investigations as to the power of 

 different varieties of grapes to produce perfect fruits without cross pol- 

 lination from otlier flowers, either on the same idant, other plants of 

 same variety, or plants of a different variety. Seventy-six varieties, 

 distributed among 8 species wdth their hybrids and crosses, discharged 

 their pollen before the corolla was entirely opened, but not all of them 

 were self-fertile, as was proved by inclosing the clusters of buds in paper 

 bags until the blossoming period had passed. The results seemed to 

 show that varieties having stamens with short filaments were in\ari- 

 ably unable to fertilize tliemselves, and tliat not all of those with long 

 filaments could do so. But the pollen of varieties that are self-sterile 

 may fertilize other varieties. 



"Under the conditions of soil and climate found at this station the following vari- 

 eties may be expected to prove unfruitful when planted hy themselves out of the 

 reach of pollen from other varieties: Black Eagle, Brighton, Eumelau, Massasoit 

 (Rogers No. 3), Wilder (Rogers No. 4), Rogers No. .5, Gaertuer (Rogers No. 14), Mer- 

 rimac (Rogers No. 19), Requa (Rogers No. 28), Aminia (Rogers No. 39), Essex (Rog- 

 ers No. 41), Barry (Rogers No. 43), Herbert (Rogers No. 44), Salem (Rogers No. 53). 



"The following varieties were found able to set fruit of themselves : Concord, Dia- 

 mond, Niagara, Winchell (Green Mountain), Rogers No. 13, Agawam (Rogers No. 15), 

 Rogers No. 24, Rogers No. 32, Delaware." 



Cross fertilization of grapes, S. B. Geeen {Minnesota iSta. Bui. 33, 

 pp. 229-231). — To test the self- fertility of grapes, bunches of Moore 

 Early, Lady, Agawam, Ives Seedling, Lindley, and Brighton were 

 inclosed in bags during the blossoming period. Lindley and Brighton 

 Avere found completely incapable of fertilizing themselves, not a single 

 berry setting, but the others all produced full bunches of grapes. 



The effect of rainfall upon pollination — note on preliminary 

 experiments, S. A. Beach and D. G. Faiiichild {New York IState Sta. 

 Bpt. 1692, pp. 007-612). — Two Duchess grapevines and two Mount Yer-
