Allelopathy of Aqueous Extracts fromCamellia oleifera Leaf and Litter Fall on Seedling Growth of Perilla frutescens

The allelopathy of aqueous extracts from the leaf and litter fall from 50-year-old Camellia oleifera(5,10,20,40mg/L different extract concentrations were prepared)on seedling growth of Perilla frutescens were observed with the contents of chlorophyll,proline,and malondialdehyde as determine indices.The results showed that the contents of chlorophyll and malondialdehyde in P.frutescens seedling were remarkably decreasing as the aqueous extracts concentration was increasing,while the proline content was increasing.Especially,the proline content reached 45μg/g at the aqueous extracts concentration of 40g/L.So,the high concentration aqueous extracts fromC.oleiferaleaf and litter fall significantly inhibit the seedling growth of P.frutescens,and the C.oleiferaforest soils could be not propitious for the seedling growth of P.frutescens.
