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...

description 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 from bugs, decay and termite attack. In this study, soil moisture content was around 0.02 % and the percentage of seed germination for okra and tomato seeds were 90 % and 80 % respectively. Furthermore, seed moisture content in okra seeds was 12.04 % while tomato seeds contained 20 % of moisture content. The germination rate of okra and tomato seeds in phyotoxicity test varied depending on the quality of seeds and concentration of exractives used. However, almost all of the tests showed no significant different of the seed germination in different concentration of cold and hot extractive solutions. Hence extractive are mainly environmentally natural chemicals in relation to generally no effect on okra and tomato seed germination.
