The one defect in the Pound method of shield budding the mango
described in Bureau of Agriculture Bulletin No. 18, The Mango, consists
of the necessity of placing an apron to protect the long petiole
left on the bud from the sun and the entrance of water, which work
necessarily requires more time than if the bud could be wrapped as is
the case in budding citrus trees. However, a possible use of scarred or
nonpetioled budwood as a means of obviating the need of the apron was
suggested in the above-mentioned publication. The results obtained
in recent experiments conducted at the Lamao experiment station
(November and December, 1914) have fully come up to the expectations
of this modification, and if the work is carefully performed, the
operator should have no trouble in obtaining 85 per cent of live buds
by proceeding in accordance with the following directions:
(1) Select budwood that is well matured, from the first, second,
and third flushes from the end of a branch. This budwood is always
green and smooth.
(2) Three weeks or more in advance of the date when the budding is to
be performed, cut off the leaf blades of the budwood selected. This
causes the petioles to drop. When the scars left after the petioles
have fallen are well healed the budwood is in condition for budding.
(3) The buds should be cut about 4 centimeters long, with an ample
wood shield, and inserted in the stock at a point where the bark is
green and smooth like the budwood, not where it is rough and brownish.
(4) Use waxed tape in tying and cover the entire bud.
(5) When in the course of two to three weeks a good union has formed,
unwind the wrapping so as to expose the leaf bud from which the growth
is to issue, and cut off the top of the stock 10 to 15 centimeters
above the bud.
(6) Every ten days after unwrapping the buds go through the nursery and
carefully rub off all stock sprouts in order to force the buds to grow.
All other precautions that are taken in ordinary shield budding must,
of course, also be attended to in order to insure success.
Experiments in Shield Budding.
After repeated attempts the shield-budding experiments at the Lamao
experiment station with the camia (Averrhoa Bilimbi) and the santol
(Sandoricum koetjape) have been successful, and it has also been found
that the barobo (Diplodiscus paniculatus), a nut tree indigenous to the
Philippines (Dillenia indica), and the sea grape (Coccoloba uvifera),
may be propagated by means of shield budding. Detailed information
relative to the budding of these plants will be published on the
completion of the experiments.
