Smith: Have you used that with pecans in the North?
Mr. Jones: Yes sir, this will be our method of propagation.
After Mr. Jones had given further illustrations of the process of
grafting, the convention adjourned.
SOME PERSIAN WALNUT OBSERVATIONS, EXPERIMENTS AND RESULTS FOR 1912
E. R. LAKE, WASHINGTON, D. C.
The Arlington work for 1912 in the propagation of the Persian walnut
consisted in top-grafting three and four year old nursery stock by
several methods, as ordinary cleft, side cleft, bark cleft, prong, whip
and modified forms of these. For wrapping we tried bicycle tape, waxed
cord and cloth, with wax and plasticine for covering.
The work was done during the latter part of April and first part of May.
The stocks averaged from 3/4 to 1-1/4 inches diameter, and were cut off
from 16 to 30 inches above the surface of the ground. In a few cases
bark grafting by modified whip form was performed upon the branches at a
height of about 4 feet.
Later in the season from June 12th to August 25th buds were placed by
varying methods. In the earlier instances the buds were taken from
left-over grafting stock. Of the scion wood received last year all the
wood from Eastern growers was frost bitten and wholly failed to take
with one or two exceptions.
The Pacific Coast wood was received in excellent condition and
operations with it were gratifying, especially with the ordinary cleft
graft, and patch bud.
Next year's work in grafting will be confined to the cleft, and the
bark-whip processes. This latter is very simple and under careful
treatment promises to be a convenient and successful process.
In the budding operations we resorted to a number of methods largely for
the benefit of the information obtained from the practice, and not so
much for the returns in propagated trees.
However, for 1913 in the work of propagating for stock results we shall
confine our practice to the patch method, though we may find from later
tests that the hinge method so favorably looked upon by Oregon is better
suited to the work.
Various experiments with tying material were tried. Raffia, cotton cord,
waxed cloth and bicycle tape were used. The raffia and cord gave best
results. A tight tie is needed.
June-budding from the left-over graft-wood gave a very low percentage of
"takes." Most of the buds appeared to be drowned. Buds from the current
year's growth inserted from early to middle of August are at present
