352 EXPERIMENT STATION RECORD. 



A test of the relative value of peach and Myrobalan pmrns as stocks 

 for peaches resulted decidedly in favor of the peach stocks. The trees 

 grafted on plum stocks were not as strong growers as the others, began 

 early to show signs of fading, and had trunks with decided enlarge- 

 ments just above the stock. 



Notes are given on a number of Russian fruits, none of which are 

 recommended for growth in Kansas. 



Dendrolene applied to the trunks of peach trees for about a foot just 

 above the ground damaged the trees in all cases, some of the trees 

 being killed. 



In germinating a quantity of peach pits it was noticed that a number 

 of them contained 2 embryos, 2 seedlings forming instead of 1. These 

 seedlings were fruited for 3 years and observed closely to determine 

 whether the 2 trees from one pit would differ from each other as much 



as seedlings ordinarily do. The author says: 



i 

 " Of the distinctness of each tree as a variety there can he no question, the trees 

 of some pairs being more distinct from each other than from trees in other pairs. In 

 other cases the 2 trees were so nearly alike as to call for an inspection of minute 

 details of leaf and gland in. order to distinguish them. The resemblance to the 

 variety from which the seed was produced was very marked, and especially in the 

 case of the seedlings from Hale Early." 



Varieties of pears and peaches, G. Coote (Oregon Sta. Bui. 52, 

 pp. 8-16, Jigs. 9). — Descriptive notes are given on several varieties of 

 pears, with outline drawings of the fruits of each. 



Notes are given on the leaf curl of peaches (Exoascus deform a us). 

 To determine whether the disease was caused by climatic changes, 

 badly affected trees of 3 varieties were transplanted in the fall of 1893 

 to half-barrels in a greenhouse, the temperature of which did not fall 

 below freezing. The trees were placed outdoors during the following 

 summer. They grew well and showed no signs of disease. The next 

 fall the trees were returned to the greenhouse. The following season 

 they were perfectly healthy and blossomed and fruited well. Buds 

 from diseased trees from the orchard were set in healthy greenhouse 

 trees. The buds grew well, only the first leaves being affected. In 

 the next fall the trees were planted in the orchard and the following 

 spring were very severely attacked by the disease. For preventing 

 leaf curl the author believes that a mixture of lime, sulphur, and salt, 

 used to spray the trees just before the buds open, is beneficial. 



Flower seed growing in America, W. W. Tracy ( Gardening, 6 

 (1898), No. 136, pp. 213, 244). — In discussing the improvement of the 

 sweet pea in America the author says : "The Extra Early Blanch Ferry 

 was not the result of the selections of the earliest flowers, but it was 

 developed on the theory that the time (from the sowing of the seed) of 

 the plant coming into flower was quite as largely affected by conditions 

 of growth as by constitutional tendency, but that the period in the 

 development of the plant when it first showed bloom was more a matter 

 of constitutional tendency than of growth conditions. Accordingly, in
