EUROPEAN GRAPES AT THE NEW YORK EXPERIMENT STATION[17]
In the spring of 1911, the Station obtained cuttings of 101 varieties
of European grapes from the United States Department of Agriculture
and the University of California. The cuttings obtained were grafted
on the roots of a heterogeneous collection of seedlings, five years
set, representing a half dozen species of Vitis. These stocks had
little to recommend them except that all were vigorous, well
established and all were more immune to phylloxera than the Old World
varieties. From four to six grafts of each of the hundred varieties
were made and a stand of 380 vines resulted, the percentage of loss
being exceedingly small. The success in grafting was probably due to
the method used, the value of which had been proved in previous work
on the Station grounds. The method of grafting and details of care
follow:
_Details of care._
In grafting, the earth was removed from the plants to a depth of two
or three inches. The vines were sawed squarely off below the surface
of the ground. The stock was then split for a cleft graft. Two cions,
made as described on page 46, were inserted in each cleft and tied in
place with waxed string. Wax was not used as it does not stick in
grafting grapes, because of the bleeding of the stock. After setting
the cion, the earth was replaced and enough more of it used to cover
stock and cion to prevent evaporation. This method of grafting is
available to those who have old vineyards. It is so simple that the
veriest tyro can thus graft grapes. Were young plants or cuttings used
as stocks, some method of bench grafting would, of course, be resorted
to.
The cultivation and spraying were precisely that given native grapes.
There has been no coddling of vines. The fungous diseases which helped
to destroy the vineyards and vexed the souls of the old experimenters
were kept in check by two sprayings with bordeaux mixture; the first
application was made just after the fruit set, the second when the
grapes were two-thirds grown. Some years a third spraying with a
tobacco concoction was used to keep thrips in check. Phylloxera was
present in the vineyard but none of the varieties seemed to suffer
from this pest. The stocks used were not those best suited either to
the vines grafted on them or to resist phylloxera. Unquestionably some
of the standard sorts used in France and California
