414 REPORT OF OFFICE OF EXPERIMENT STATIOTSTS. 



In a later work the New Jersey Station found that pits from natural 

 seedlings are more vigorous than pits from improved varieties. In 

 one experiment" from 620 pits from seedling trees 108 trees were 

 secured, while from 321 pits of improved varieties only 7 trees were 

 secured. Wherever natural pits can be obtained stock pits from the 

 canning house should not be used. Peach seed is usually stratified 

 and subjected to the action of frost before planting, othermse it 

 should be cracked. 



The Kansas Station'' has made observations on the character of 

 trees produced by peach pits containing two embryos as compared 

 with those containing only one. In some cases the two trees are so 

 nearly alike as to make it difficult for inspection of minute details in 

 order to distinguish them, while others were quite noticeably distinct. 



Budding is easier and more successful with peaches than grafting. 

 In the North, seedling stock 1 year old is budded anyA\^here from the 

 latter part of August to the first week in October. June budding is 

 practiced in the South with fair success, but in the North such buds 

 make a weak, late growth that is likely to be injured by a severe 

 winter. 



The Texas Station describes a successful method of budding peach 

 trees late in the fall when the bark will not slip.*^ The method is an 

 old German one, but was worked out independently b}^ the station. 



It consists of cutting a slip of bark, with some wood attached, down the tree about 1 

 incli , leaving it attached at the lower end. About half this slip is then cut off, leaving 

 the other half still attached to the tree. Cut off a bud, leaving some wood also attached 

 to it to prevent injury, and then carefully place it between the slip and tree so that 

 it will fit nicely and the cambium of the bud and tree come in contact. Tie tight with 

 some good material, such as raffia. In five or six days the bud will be found to have 

 knit firmly. Treat them then as those budded in the usual way. 



STOCKS FOR THE PEACH. 



The peach usually gives best results on peach stock. At the Cali- 

 fornia'^ Station peaches on almond stocks made fairly large trees. 

 Peaches on Myrobalan stocks fruited earlier than on peach stocks, 

 but were dwarfish and unsatisfactory on the soil used. At the Kansas 

 Station'' 47 trees were budded on peach stock and 44 on Myrobalan. 

 Six years later 24 of the trees on peach stocks were soimd and vigor- 

 ous, while all peaches on M>Tobalan were either dead or in ver}^ poor 

 condition. 



N. E. Hansen reports'^ out of 56 grafts made with the Bokhara 

 peach on sand cherr}^ stock (Prunvs besseyi) onl}^ 1 grew. Much bet- 

 ter success was secured in budding on this stock. The tree is
