Improved Techniques Developed for Grafting Slash and Longleaf Pine

Difficulties encountered in grafting mature longleaf pine (Pinus palustris Mill.) for establishment of seed orchards are well known. To circumvent the problems created by the "grass stage" in longleaf pine, seedlings grown from windpollinated seed from a natural hybrid of slash (P. elliottii Engelm.) and longleaf pine can be used for rootstock. The seed is sown at 10by 10-inch spacing in the nursery bed in the spring. The resulting seedlings do not have a grass stage and reach sufficient diameter in one growing season for use as grafting stock for longleaf scions. These seedlings are lifted with a council tool and potted in the fall after height growth ceases. They are then placed in the greenhouse, where grafting is done in February. After grafts become established, they are put outside to harden off. Grafts can be outplanted in the seed orchard in spring or early summer. Longleaf grafts grow well on this rootstock.
