| dc.description.abstract | The increase in concentration of allelochemicals, both from plant and seeds of Parthenium, caused decrease in the germination of Raphanus seeds. The seed germination was inhibited up to 100% in the presence of Plant diffusates (PD) and up to 86.66% in the presence of seed diffusates (SD). These allelochemicals also reduced the glucose level in germinating seeds of Raphanus sativus. The glucose level reduced up to 55% in 100 % PD grown seeds and up to 37% in 100% SD grown seeds. Extracts (essential oils) from Eucalyptus citriodora, Cymbopogon citratus and Cinnamomum camphora were used to analyze their effects in germination and seedling development of the weed. Cymbopogon oil at 8 ml l-1, Eucalyptus and Cinnamomum oils at 12 ml l-1 and all above concentrations of all extracts arrested the seed germination of the weed completely. The oil extracts irrespective from their sources were found significantly effective (P < 0.05) in arresting the seed germination and seedling length of Parthenium hysterophorus in laboratory conditions. | en_US |
