Allelopathic Potential of Polygonum orientale L. in Relation to Germination and Seedling Growth of Weeds

Flora: Morphology, Distribution, Functional Ecology of Plants

ALLELOPATHIC POTENTIAL OF CLERODENDRUM-VISCOSUM-VENT IN RELATION TO GERMINATION AND SEEDLING GROWTH OF WEEDS

Both extract as well as leachate of Croton bonplandianum leaves before or after washing are detrimental to at least six weedy associates, viz. Calotropis procera, Chrysopogon aciculatus, Crotalaria saltiana, Cynodon dactylon, Eupatorium odoratum and Polygonum orientale. By adding increasing quantities of decaying leaves to soil, phytotoxic activity is greatly enhanced against at least Crotalaria saltiana, Cynodon dactylon and Evolvulus nummularius. Soil samples collected in and around Croton bonplandianum plants during active growth of the species are more toxic to weedy associates than the soil collection made after accumulation of debris of Croton plants. The weeds that are mostly affected include Chrysopogon aciculatus, Cynodon dactylon, Eupatorium odoratum, Evolvulus nummularius and Mikania cordata. Maximum amount of inhibitory compound from Croton bonplandianum leaves are extractable in ethanol. The ethanol extract, on further analysis, leads to the finding that two active constituents are involved and that these constituents are probably related to abscisic or phaseic acid. The implications of the above results are discussed. © 1975 Dr. W. Junk b.v. Publishers.
