arently in good dormant condition.
Some July buds from the left-over graft-wood placed in the younger
branches of a twelve year old American black took well and made from
three to six inches growth. The branches were cut back as soon as the
buds appeared to be set, a course that would not be advocated if one
were doing the work for re-topping. The young wood from these buds is
delicate and soft and in order to insure their living through the
winter, so far as our efforts may avail, they have been enclosed in
strong paper bags. In our budding and grafting operations we had no
success with the Japanese or Chinese stocks. We expect to try them
further as their rapid growth makes them much to be desired if a
permanent union can be effected. So far as we have been able to learn
from the southern propagators who have worked along this line, no
difficulty has been encountered in effecting a short-life union,--four
to six years on an average, though a few have kept alive for twelve
years.
The growth of the successful grafts has been very variable. In several
instances in which both scions upon a stock grew, the growth was from
two to three feet. In other cases the young wood was scarcely a foot
long.
The fact that the stocks and scion-wood varied widely in size and vigor
and the further fact that the scions were from several varieties of
western stock are quite sufficient causes for no uniform results in this
respect.
The wood of all successful grafts appears to be in excellent condition
for the winter season and we are looking forward to an interesting
further growth of these next year, though the trees have just been
transplanted. In order to doubly insure ourselves against loss of the
varieties now growing one half, or even more in a few instances, of the
young wood has been removed and placed in a cold room so that further
grafting or budding of these varieties may be made next year.
Nursery trees of the Franquette, Pomeroy, Parisienne and unidentified
others, on their own roots are making a pitiable effort at successful
growth, while all wood on the black stock is making excellent growth.
In one instance the wood of Mayquette a cross between Mayette and
Franquette formed two nutlets. Lack of pollen was all that prevented the
fruiting of one-year-old grafted trees. A splendid point for the unit
orchard booster, but a point of no value to the real walnut grower.
