|A European Hazelnut with a large number of two-year-old suckers|
We also know that unprotected grafts are very vulnerable to drying out before the graft heals.
There is very little data on the internet that quantifies how sensitive drying times are to length-of-stick or the ratio of surface that is cut-end and surface that is covered-by-bark
Seven, 28" stems were cut from the 2-year-old suckers between approximately 48" and 72".
Each subsection of stem was further divided as follows:
-The first 4" (100mm) closest to the bottom was identified as "A"
-The second 4" was identified as "B"
-The next 16" (approx 400mm) was identified "C" on four stems and "D" on three stems.
-The last 4" was also identified as "B" such that each 16" section contributed to the population of "B" from both upper and lower end for a total of 14 "B" segments.
The "A" Team
The seven, 4" segments identified as "A" will be kiln dried to determine starting moisture content. The initial weight of "A" Team was 297 grams or 10.61 grams/inch. The reason to know the initial moisture content is to know when to terminate the "run" for each population. In this case, I will use a target of 20% moisture, by weight.
The "B" Team
Will provide a data point in how quickly sticks dry when the ratio of cut-end to covered-by-bark is high. The initial weight of "B" Team was 517 grams or 9.23 grams/inch
The "C" Team
Will provide contrasting data to "B" Team and provide data of how quickly sticks dry when the ratio of cut-end to covered-by-bark is low. The initial weight of "C" Team is 598 grams or 9.34 grams/inch.
The "D" Team
Is identical to "C" Team except the cut ends were dipped in melted paraffin to essentially model a stick of infinite length that is totally covered in bark. The initial weight of "D" Team is 422 grams or 8.79 grams/inch
The samples will be placed on a pallet which will rest on the ground. The pallet will be placed in an open area where it will be exposed to the elements. I need to work out some kind of wire mesh basket so precipitation can drain away freely.
The shorter pieces "B" will dry out significantly faster than the longer pieces "C" which will in turn dry significantly more quickly than the longer pieces with the ends coated "D". I expect each population to take approximately twice as long to reach 20% moisture as the previous class.
I can already report an initial finding. Toasting hazelnut wood smells delicious!
Second initial finding, dry-weight of "A" after kiln was 147 grams so water comprised 50.5% of the samples as-cut.
