Sounds like you answered your own question. Every single source is going to be different, so there is no answer without testing your desired product.
Hemicellulose: about the same as cellulose
Lignin: approx (C3H3O)n

The sky is my canvas, and I have 2,113 pounds of powdered paint in the workshop.

Add to that there is no consensus of the true reaction stoichemetry of burning black powder, there are too many ways to produce the known combustion products. Also powder burned under pressure seems to produce different products from powder burned loose. Add in all the variables of different woods and there will be no way of determining the final reaction mechanism.

If you are talking about soaking solid wood in KNO3, I think the wood will not absorb enough nitrate for an stechiometric reaction. Look at cotton rope impregnated in KNO3. It's more porous than wood, its made with saturated solution, and it hardly burns.

Since wood, starch, and sugar are all approximately CH2O, I would use this equation:
5 CH2O + 4KNO3 --> 2K2CO3 + 3CO2 + 5H2O + 2N2,
or about 2.7 parts saltpeter to dry wood. Like Baldor said, you're not probably not going to get a dowel to soak up nearly 3 times its weight in saltpeter, unless it's a very low density wood like balsa. It would work a lot better with a mix of sawdust and powdered saltpeter.
Also, what kind of wood are you using? "Soft" resinous woods like pine and cedar have a lot of pitch and tar, so you would also need more oxidizer. Then again, the resin might make them easier to light.
