Soil contamination from wood extractives affecting plant seed germination

Wood extractives are non-cell wall component which usually contain only 1-5 % or up to 20 % in wood. It can be solubled in non-polar organic solvent and in water. Therfore, it can be extracted by using water, acetone, ether or ethanol. Wood extractives in trees function as a protecting barrier fr...
