Abstract
As an aggressive and noxious weed Parthenium hysterophorus is spreading very rapidly in various agricultural fields and along roadsides by eliminating various plants species. It is very hazardous to agricultural land, human and animal health. So, an attempt has been made to study the reproductive capacity and growth performance of P. hasterophorus under the influence of leachates of dried and dropped red leaves and phenolic compounds (Tannic acid, Gallic acid and Catechol) against P. hysterophorus. In Parthenium average flower-heads and seed output was 178.5 and 714 and reproductive capacity was found to be 135.38, 387.41 and 519. 35 at 48, 72 and 96 hours respectively. 20.33, 54.83 and 72.13 was germination percentage at 24, 48 and 72h with 0.64 cm root length and 1.00 cm shoot length. In petriplate bioassay seed germination was completely suppressed due to the effect of 10% and 20% red leaf leachate. Root length and shoot length were reduced due to 20% red leaf leachate. In petriplate and soil bioassay, root and shoot length was inhibited due to phenolic compounds (20ppm Tannic acid, 20ppm Gallic acid and 20ppm Catechol) and 5%, 10% and 20% red leaf leachates. Total phenolic content was highest in 20% red leaf leachate (160.86 mg/100ml) as compared to 5% and 10% red leaf leachates. Anthocyanin content in red leaf was 0.76 Absorbance units. The Phytochemicals trans-9-Octadecenoic acid, Bis (2-ethylhexyl) phthalate, Diisooctyl phthalate, l-(+)-Ascorbic acid, Phenol and Phthalic acid were detected in red leaf leachates by GC-MS techniques. The adverse effect of red leaf leachates of T. catappa on the growth performance of P. hysterophorus may be due to phytochemicals present in the leaf leachates.
