I need a solution for healing tree grafts. Fruit trees are often propagated in the spring by grafting (attaching) a piece of scion wood to rootstock. The graft must "heal" which means that the outer "cambium" layers of the two pieces join together. This process occurs around room temperature and takes 7-10 days. If the entire "tree" is exposed to room temperature, however, it may break out of winter dormancy and start to bud early (before the danger of frost has disappeared).
I envision a solution whereby a length of Ni-chrome wire is spiral wrapped around a .25" diameter size piece of wood for about 1" in length. Once connected to a power source, the grafted region can be heated to a "healing" temperature, while the rest of the tree is kept in a refrigerated environment.
I have several different gauges of Ni-chrome wire with which to experiment. I have a table that enables me to calculate power dissipation, but no way of knowing how much heat that will produce. Does anyone have an idea of a measuring device or datasheet that would enable me to measure the internal heat experienced from the spiral wire wrap?
Thanks for your help.
