Abstract

Allelopathic potential of Dicranopteris pedata, Acacia auriculaeformis, Cinnamomum burmannii, and Melastoma malabathricum, for ecological control of Ipomoea cairica.

Abstract

In pot culture, we studied the individual and combined effects of aqueous leachates of four common plants [Dicranopteris pedata (Houttuyn) Nakaike, Acacia auriculaeformis A. Cunn. ex Benth, Cinnamomum burmannii (Nees et T. Nees) Blume and Melastoma malabathricum L.] in southern China on physiological properties (biomass allocation, photosynthetic characteristics and allelopathy) of I. cairica L. The results showed that (i) the extracts of single species and the mixed leachates had allelopathic effects on photosynthetic activities and growth of I. cairica L., (ii) the allelopathic effects increased with the increase of leachates concentrations and (iii) the mixed leachates of 4-species at 200 mg.L-1 concentration was most inhibitory to the invasive specie I. cairica. Our results indicated that the aqueous leachates of these four donor plant species may control the exotic invasive species I. cairica.
