Green leaf part including its petiole had
dropped off from all five scions. A small slit in the bark of each graft
for investigation showed that the cambium was green in four grafts, the
fifth graft was completely dead.
Exp. No. 2. On July 28th three persimmon scions consisting of last
year's wood and each one carrying a couple of inches of new growth with
a terminal trimmed leaf were grafted into last year's wood on another
persimmon tree. Note. Sept. 9th. All three grafts dead including both
old and new wood.
Exp. No. 3. July 28th. One green persimmon scion with terminal leaf
inserted in bark slot of branch one inch in diameter cut back for
purpose. Note Sept. 9th. Dead.
On August 2nd the drought had been broken. All trees seemed to have put
up top buds on account of drought and heat. The following experiments
were made with green growth of the year but with new top buds much to my
regret at having no actively unfolding shoots for furnishing scions.
Exp. No. 4. Aug 2nd. Persimmon tree (a) One graft, green on green; one
green graft on old wood. Note. Sept. 9th. Terminal leaves remained green
several days after grafting but by Sept. 9th all had fallen off. Small
slit in bark showed cambium of grafts still green.
Persimmon tree (b) Two green grafts on green. One green graft in bark
slot of older wood. Note Sept. 9th. Terminal leaves had finally died but
two of the buds of green graft on green have burst forth into leaf.
These will probably winterkill. Green in old wood has green cambium but
no swelling bud.
Exp. No. 5 Aug 2nd. Persimmon tree (c) One green on old wood. Sept. 9th.
Leaf dead, cambium of stem green.
Exp. No. 6. Aug 2nd. Persimmon tree (d) One green on old wood. Sept.
9th. Leaf dead, cambium of stem green.
Exp. No. 7. Aug. 2nd. Persimmon tree (e) Three greens on old wood. Sept.
9th. Leaves dead, one stem dead, cambium of two stems green.
Exp. No. 8. Aug. 2nd. Papaw tree. Two greens on green, two greens on old
wood. Sept. 9th. Two greens on green have buds enlarged and ready to
burst. One green on old wood is not enlarging its buds. One green on old
wood is dead.
Exp. No. 9. Aug. 2nd. English walnut. Four greens on green. Sept. 9th.
Leaflets dead on all. Petiole dead on one, stem cambium green. Petioles
bright green on three and the cambium green on these.
Comment. I could not take daily notes which would have been very
important. A general statement will cover the point that the termin
