Abstract
Allelopathic effect of larch (Larix gmelini) leaching on ash (Fraxinus mandshurica) growth was studied with sand culture test. It was understood that the ash growth was stimulated by the larch leaching. The chemical compositions of the larch and ash leaching were identified and determined by chemical and instrumental analysis. The results showed that in the larch and ash leaching there were fatty acids (including monocarboxylic, dicarboxylic and tricarboxylic acids), phenolic acids, tannin, aromatic alcohols, polylol, aminoacids and carbohydrate, etc. On the basis of the analytical results of chemical composition, with reference to the results of model compound test, it is considered that the citric acid in the larch leaching was the main simulative allelochemical to the ash growth, and trihydroxybenzeneacetic acid was the subordinate stimulative allelochemical.
