Abstract

Background: In order to establish a scientific and reasonable intercropping pattern of Taxus chinensis var.mairei, allelopathic effects of the aqueous extracts from Taxus chinensis var.mairei on seed germination and seedling growth of rape (Brassica campestris L.), radish(Raphanus sativus L), soybean (Glycine max). Materials and Methods: lettuce (Lactuca sativa) were studied by the methods of bioassay. The results showed that the seed germination and seedling growth of four kinds of crop were dramatically inhibited when the aqueous extracts are in higher concentration , and the inhibition enhanced with the increase of the aqueous extract concentrations; lower concentration of the aqueous extracts promoted the seed germination and seedling growth of rape, radish and lettuce. Results: The allelopathic effect of the aqueous extracts from Taxus chinensis var.mairei underground part on different crops was stronger than that of aerial part. Perhaps Taxus chinensis var.mairei may contain some allelochemical, which interferes with seed germination and seedling growth of these plants, and the comprehensive inhibition effect were greater than the promoting effect. Conclusion: Consequently, the study suggests that rape, radish, soybean and lettuce are not suitable for intercropping with Taxus chinensis var.mairei, and hypothesizes that dicotyledonous crops are basically not suitable for intercropping with Taxus chinensis var.mairei.
