Abstract
Allelopathy of aqueous extracts of Kochia scoparia and its different parts on flax(Linum usitatissimum) were tested by the methods of bioassay.The results showed: 1) Different concentration of K.scoparia and its stem and leaf aqueous extracts have different degree's inhibition on flaxseed germination and seedling growth,and the inhibition rate increased with the increasing concentration of extract,0.100 g/mL whole plant and its stem and leaf aqueous extracts of K.scoparia have 100% inhibition rate to the germination energy,germination rate,germination index,vigor index and root length,shoot height,root fresh weight and shoot fresh weight.2) The aqueous extracts of K.scoparia inhibit flaxseed germination was mainly because they inhibit vigor index,and they inhibit the growth of flax seedlings was mainly because they inhibit root growth.3) K.scoparia aqueous extracts showed allelopathy effect to the germination and seedling growth of flaxseed,which indicated that K.scoparia release allelochemicals in various ways(such as rainoff eluviation,root excretion,etc.).But according to the inhibition synthesis effect,at the same concentration of aqueous extracts,the stem and leaf has the strongest allelopathy on flaxseed,and the root has the least allelopathy.
