彩色豆马勃发酵液和菌丝体提取液对几种植物的化感作用

Allelopathic Effects of Fermented Mycelia and Broth of Pisolithus tinctorius on Several Higher Plants

彩色豆马勃(Pisolithustinctorius)的发酵液在6 25%、16 67%的体积分数下对稗草(Echinochloacrusgalli)、水稻(Oryzasativa)和萝卜(Raphanussativus)等高等植物的幼苗生长有显著的促进作用,在6 25%体积分数下对油菜(Brassicacampestris)的幼苗生长有促进作用;彩色豆马勃菌丝体的乙醇提取液在15 00、7 50和3 75mg/mL等质量浓度下对稗草、萝卜和油菜均有明显的抑制作用;在15 00mg/mL质量浓度下对水稻幼苗的生长有抑制作用,但在7 50和3 75mg/mL质量浓度下对水稻幼苗的生长有促进作用.

Allelopathic effects of fermented broth and ethanol extracts of fermented mycelia of Pisolithus tinctorius were investigated. The fermented broth significantly stimulated the seedling growth of nonhost plants such as barnyardgrass,rice, radish and rape at concentrations of 625%, 1667% (φ). The ethanol extracts of the mycelia significantly inhibited the seedling growth of barnyardgrass, radish and rape at concentrations of 1500, 750 and 375 mg/mL, and inhibited the seedling growth of rice at a concentration of 1500 mg/mL. But the ethanol extracts of Pisolithus tinctorius mycelia significantly stimulated the seedling growth of rice at concentrations of 750 and 375 mg/mL.
