Abstract:
OBJECTIVETo study the interspecies allelopathy of Glycyrrhiza uralensis and Caragana microphylla and reveal the relationship between different interactions and provided the theory reference for their application of compounding planting pattern in practice.
METHODWater extracts of G. uralensis and C. microphylla root, stem and leaf were used to dispose mutual seeds, young seedlings and transplants.
RESULTThe germination of G. uralensis seed wasn't restrained significantly by the water extract of C. microphylla root, stem and leaf (1-50 g x L(-1)). However, the inhibitory effect of a high concentration water extract of C. microphylla stem and leaf (50 g x L(-1) was stronger. There wasnt significant difference in the effect of the water extract of C. microphylla cast, root and stem on the growth and quality of G. uralensis transplant. Moreover, the water extract of G. uralensis root, stem and leaf can improve the germination of C. microphylla seeds and the growth of seedlings, while its effective extent didn't reach an obvious different level.
CONCLUSIONThere exists no significant difference between the interspecies allelopathy of G. uralensis and C. microphylla.
