    • 摘要: 从广州地区采集月季、杜鹃、卡特利利亚兰、康乃馨、蒲包花、长春花、一品红、百合和绿巨人共9种花卉疫病标本,根据病原菌性和无性形态特征,结合生长温度和菌体可溶性蛋白聚丙烯酰胺凝胶电泳,将它们分别鉴定为:Phytophthora citricola Sawada(为害月季)、P.citrophthora(R.E.Smith&E.H.Smith)Leonian(为害杜鹃)、P.palrnivora(But

       

      Abstract: Phytophthora isolates were obtalned from 9 species of diseased floral plants Rosa chinensis Jacq. , Rhododendron spp. L., Cattleya bowringiana Hort., Dianthus caryophyllus L., Calceolaria crenatiflora Cav., Catharanthus roseus (L. ) G. Don, Euphorbia pulcherrima Willd. ex Klotzsch, Lilium spp. L. and Spathiphyllum pallas Hort. collected in Guangzhou region. On the basis of the sexual and asexual characteristics of their single-spore cultures combined with the cardinal temperatures and the eletrophoresis of their proteins patterns, they were identified as: P. citricola Sawada (on Rosa chinensis), P. citrophthora (R. E. Smith & E. H. Smith) Leonian (on Rhododendron spp. ), P. Palmivora (Butler) Butler (on Cattleya bowringiana and Dianthus caryophyllus), and P. nicotianae Breda de Haan (on Calceolaria crenatiflora, Catharanthus roseus, Euphorbia pulcherrima, Lilium spp. and Spathiphyllum pallas ).
