EXPERIMENT STATION REPORT. 369 



While no definite statement can be given as to the ages of the 

 plants grafted, the rule was to have the plants old enough to 

 withstand mutilation and yet young enough to insure rapid union. 



Tomato upon "Garden Huckleberry" (Solanum nigntm). The 

 attempts gave one success. The graft rapidly increased in 

 height, but its foliage was scant. It was set out in the 

 field where it lived until the middle of August, having time 

 to produce one fruit which was an inch in diameter. The 

 seeds were ma'ny, and when started grew vigorously. No 

 effect of tlie "Huckleberry" stock was noted. 



'Garden Huckleberry" upon Tomato. Two attempts gave one 

 success. The graft was vigorous and, when set out in the 

 field, it grew until the autumn frosts. The scion and stock 

 both produced an abundance of their own kind of fruit. 

 Seeds were many in every fruit and produced seedlings 

 rapidly. No effect of tomato stock upon "Huckleberry" was 

 noted. 



Tomato upon Eggplant. Two attempts gave no success. 



Eggplant upon Tomato. Two attempts gave one success. The 

 graft at first was not vigorous, but when set out in the field 

 it grew well and matured many tomato fruits and one egg- 

 plant fruit; the latter was small and its seeds started well. 

 No effect of eggplant upon tomato was noted. 



Tomatoes : Fine-Leaf and Coarse-Leaf. Eighteen attempts were 

 made to graft tomatoes: Nine fine-leaved upon coarse- 

 leaved, and nine reciprocals. While all the grafts started, 

 two were weak and died within a month; only nine out of 

 the sixteen were fit to go into the field and, within a week, 

 two died, leaving seven grafts that grew vigorously through- 

 out the season. These grafts represented five coarse-leaved 

 upon fine-leaved, and two reciprocals. Only one graft-plant 

 (a fine- upon a coarse-leaved) showed the effect of the union ; 

 the leaves from stock and scion were the same and not as 

 coarse nor as fine as the foliage of the original parents.
