ood of grafted trees is curly or not.
I sent Mr. Reed a limb from Lamb and he gave it to the forest laboratory
and they found no evidence of curly grain."
Rick: "Shouldn't it be propagated until we are sure?"
Stoke: "We had Mr. Lamb himself talk before us at Roanoke and he told us
about the parent tree. He doesn't know what makes one tree curly and
another not."
Korn: "Is that uncommon?"
Stoke: "Not so very. Trees are most curly at the base and in the outer
wood."
Question: "Do you always leave that stub on black walnut?"
Stoke: "Yes, but it should be removed later in the first summer."
Question: "Where do you use your splice graft."
Stoke: "On anything other than walnut, if scion and stock are the same
size. Where stock is larger than scion I use the modified cleft graft up
to sizes approaching one inch in the stock. For topworking larger stocks
I use one of the forms of bark graft. For the large hickory stock Dr.
Morris' bark slot graft is preferred. For large, thin-barked stocks the
simple bark graft may be used. My original grafts of the Carr and Hobson
Chinese chestnuts, made with scions received from Messrs. Carr and
Hobson in the winter of 1932, are still perfect unions.
"I believe that grafted chestnuts growing in frost pockets are most
likely to develop faulty unions; possibly frost injury to immature cells
at the junction point may occur. Dr. Crane mentions a similar failure of
unions between Persian and black walnuts on the Pacific Coast."
Dr. Crane: "What cut did you use in grafting those chestnuts?"
Stoke: "Modified cleft. In using Dr. Morris' bark slot graft I find it
best to leave just a little of the cut face of the scion wedge above the
top of the stock. This, with top of the stock cut sloping away from the
scion, as illustrated, promotes quick healing with no 'die-back.'"
Dr. Smith: "Is that top slanting?"
Stoke: "Yes, I cut it slanting."
Dr. MacDaniels: "That is a good graft for walnuts, too."
Note: Mr. Stoke showed the group a picture of a mockernut tree in one of
his fields which he had girdled to kill it. The tree lived four years
and during those years the moisture had to go up through the inner wood.
The substance of Mr. Stoke's talk, together with illustrations, may be
found on page 99 of the 1946 report.
