MUHAMMAD SAEED*, MUHAMMAD ASHFAQ AND BAKHTIAR GUL
Abstract
An experiment was conducted to investigate the potential of various allelopathic plants in Weed Science Laboratory Khyber Pakhtunkhwa Agricultural University Peshawar in 2010. The trial was replicated three times with Completely Randomized Design (CRD) having seven treatments i.e., Control (Tape water) sunflower (Helianthus annuus L.), sorghum (Sorghum bicolor L.), horse purslane (Trianthema portulacastrum L.), parthenium (Parthenium hysterophorus L.), datura (Datura alba L.), and eucalyptus (Eucalyptus camadulensis L.). Horse purslane seed germination was recorded for 15 days regularly and after 15 days root and shoot length data was recorded. The results revealed that Helianthus annuus water extract reduced germination (10.31%), shoot length (0.25 cm) and root length (0.28 cm) of horse purslane as compared to control which showed germination (86.72%), shoot length (1.81 cm) and root length (2.43 cm). The degree of percent germination inhibition of horse purslane was in the order of Helianthus annuus> Parthenium hysterophorus> Datura alba> Sorghum bicolor> Eucalyptus camadulensis> Trianthema portulacastrum> Control.
