Abstract
Field-grown mature plant residues (debris) of purple nutsedge and barnyardgrass were incorporated into the soil to determine their allelopathic potential on the emergence and seedling growth of corn. Influence of temperature on the magnitude of weed residue effects was also investigated. It was found that soils incorporated with weed residues reduced both the cumulative and the maximal emergence rates of corn at 20 and 25℃ but not at 33℃ of purple nutsedge treatment. 本研究旨在探討土壤分別混以香附子與稗草之成熟植株對於玉米（臺農一號）幼苗出土及幼苗生長之相剋效應，並瞭解不同溫度條件（20、25、及33℃）下此兩種雜草植株殘留物之差異影響。結果顯示，除了香附子殘留物處理在33℃狀況下之外，兩種雜草殘留物在設定之溫度範圍內均降低玉米出土率及出土百分比。
