low functioned as the cells above, there
would be no question about the stock and scion being the same.
Mr. Littlepage: Of course there must be sufficient flow of sap to
distribute food. The hickory root might not send the flow of sap as fast
as the pecan top would like.
Mr. Reed: Is Mr. Lake's point always true, that the stock below the
point of union remains a normal hickory?
Professor Craig: I don't believe there are more than one or two
exceptions noted to that, and those exceptions are recorded under graft
hybrids.
Mr. Reed: A seedling pecan tree owned by Mr. B. M. Young of Morgan City,
Louisiana, was top worked with scions from the McAllister hican some
seven or eight feet above ground, and later on the bark of the pecan
trunk below the point of union became scaly like that of the hican
above.
Professor Lake: That would suggest something worth while, if that part
below would produce fruit like the part above, but I would want to
question a little the modification in bark characteristics being a
direct result of cross grafting.
Mr. Reed: Of course, it was no check--only one instance.
Professor Craig: There are one or two others that are authentic. I have
known a case of plum. Here we have the plum stock, we will say it is
_Prunus Americana_, grafted with _Prunus triflora_, the Japanese, then
later on, _Prunus domestica_ is put on top. I have seen a sprout from
triflora bearing Japanese plums, while the top of the tree bore _Prunus
domestica_, although there was only a small section of stem in there
between our two distinct species. They were perfectly normal.
President Morris: Each elaborates its own kind of food in its own kind
of cell. I would like to hear from Mr. Brown and Mr. Wilcox on this
matter of grafting--the influence of stock on scion.
Mr. Wilcox: We had a good show of stocks, but instead of allowing them
to become established in the pots, we grafted them as they started into
growth after rooting. Had they been established, we would have expected
better results.
Professor Craig: What method do you employ?
Mr. Wilcox: Side grafting.
Professor Craig: Do you mean whip grafting?
Mr. Wilcox: Side whip grafting.
Doctor Deming: I would like to ask Doctor Morris what he thinks of the
practical future of grafting our hickory seedlings with improved
varieties of hickory or pecan, and the method most likely to
succeed,--whether grafting or budding, and at what season. It is
