President Morris: It is a very timely paper. The number of promoters we find in connection with any subject furnishes an index of the fundamental value of the original proposition. The number of dishonest people, the number of fakirs that are now promoting development schemes in connection with the pecan indicates that down at the bottom somewhere, there is a real gold mine. We will go on to Mr. Roper's paper.
SOME FACTS CONCERNING PECAN TREES FOR PLANTING
IN THE NORTH.
W. N. Roper, Petersburg, Va.
Pecan trees for successful culture in the North must be of hardy, early-maturing varieties, budded on stocks from northern pecans and grown in nursery under suitable climatic conditions. These are requisites indicated by practical, experimental work and observations extending over several years.
The successful production of large southern pecans in far northern climates can hardly be looked for except under the most favorable conditions of soil, location and season. There seems no good reason for planting southern pecans in the far North, except in an experimental way; for there are northern varieties now being propagated that are the equal of most of the standard southern sorts in quality and very little below them in size. They will prove to be as large or larger in the North than the southern varieties grown in the same locality, and much more apt to bear regularly.
The method used in propagating the hardy types is important. Budding and root-grafting each has its advocates among pecan growers in the South, and this would indicate that there is no great difference between the trees propagated by these two methods when they are planted in that section. But based on results with several hundred specimens, root-grafted pecan trees are not desirable for planting in northern climates.
During the past six years there have been grown in nursery, in the eastern part of Virginia, near Petersburg, about 2,000 root-grafted trees of eight southern varieties of pecans and one Virginia variety, including Stuart, Van Deman, Moneymaker, and Mantura. All these trees are worthless. None of them, though they have been cared for, has ever been considered by the grower fit to dig and transplant. Most of these trees suffer winter injury each year, many of them being killed back to the graft union. Those that do not die below the ground grow out the following summer, only to be killed back again the next winter or spring. Those damaged only a part of the way down the trunks, even when not badly injured, do not recover promptly. Several hundred budded trees grown during the same period in adjoining rows have been entirely free from any winter injury. The grafts and buds were inserted on stocks from northern and southern nuts.
A thousand budded and root-grafted trees received from six southern nurserymen were planted in orchards in the same locality. A very large percentage of the root-grafted trees died; only a small percentage of the budded trees died. Many of the root-grafted trees that survived are making poor growth; most of the budded trees are strong and vigorous. The only trees of the Virginia varieties ever reported winter-killed were root-grafts.
No root-grafts of the northern types on northern stocks have been made in Virginia, but root-grafts of Indiana varieties on southern stocks transplanted there winter-kill badly. Several Indiana trees root-grafted on southern stocks and in their second year's growth in the nursery winter-killed in Florida last season. Not a single budded Indiana tree in Virginia suffered any winter injury whatever, although the buds were grown on southern as well as on northern stocks. All the root-grafted Indiana trees transplanted at Petersburg during the past two years have died from winter injury.
