Allelopathy of Phenolics from Decomposing Stump-Roots in Replant Chinese Fir Woodland

Allelopathy of Phenolics from Decomposing Stump-Roots in Replant Chinese Fir Woodland The change of total phenolic content in decomposing Chinese fir stump-roots of different ages in replant woodland and its effects was investigated. The total phenolic contents in stump-roots decreased with increasing stump-root age. The order of total phenolic content in different parts of stump-roots was, root > stump heartwood > stump sapwood. Phenolics released from Chinese fir stump-roots reduced the growth of fir seedlings. The growth of Chinese fir seedlings was negatively correlated with total phenolic content in stump-roots that had been added to the soil. Extracts of Chinese fir stump-roots inhibited fir seed germination. The results, based on paper chromatography and HPLC, revealed that eight phenolic compounds were present in the Chinese fir stump-roots. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Chemical Ecology Springer Journals

Abstract

The change of total phenolic content in decomposing Chinese fir stump-roots of different ages in replant woodland and its effects was investigated. The total phenolic contents in stump-roots decreased with increasing stump-root age. The order of total phenolic content in different parts of stump-roots was, root > stump heartwood > stump sapwood. Phenolics released from Chinese fir stump-roots reduced the growth of fir seedlings. The growth of Chinese fir seedlings was negatively correlated with total phenolic content in stump-roots that had been added to the soil. Extracts of Chinese fir stump-roots inhibited fir seed germination. The results, based on paper chromatography and HPLC, revealed that eight phenolic compounds were present in the Chinese fir stump-roots.
