摘要
杧果细菌性黑斑病是杧果上的三大病害之一,近年来在我国各杧果产区造成严重的危害,而选育抗病品种是防治植物病害最经济有效的途径,因此本试验对海南19个栽培品种进行了田间人工接种,测定了其对细菌性黑斑病的抗病性。结果表明,杧果古铜色叶、淡绿色叶和深绿色叶3种叶龄叶片中,古铜色叶最抗病,病害在同一叶龄叶片上的潜育期长短在不同杧果品种之间有差异,但大部分的潜育期为6 d左右;其次品种间的抗病性有明显差异:越杧较感病;封顺无核杧、金穗杧、四季杧、红杧、粤西1号、紫花杧、生紫杧、马切杧、台农、爱文杧、热杧和凯特中等抗病;香蕉杧、米杧、龙井、大白玉、红象牙杧和桂香较抗病;未发现高抗或免疫的品种。
Mango bacterial black spot is one of the 3 important mango diseases and cause serious damage in China in recent years. Breeding and selecting resistant cultivars is the best way for solving such problem. Resistance of 19 mango cultivars to bacterial black spot disease （Xanthomonas campestris pv. mangiferae-indicae ） was evaluated by artificial inoculation in field. The result showed that the bronze leaf cultivars were more resistant to this disease than pale-green or dark green leaf cuhivars. The average latent period of the pathogen was about 6 d. However, the latent period was different on leaves among the mango cultivars. Yuemango was a susceptible cultivar; Fengshunwuhemango, Jinsuimango , Sijimango, Hongmango, Yexi No.l, Shengzimango, Maqiemango, Tainong, Irwin, Remango and Keitt were moderately resistant, while Xiangjiaomango, Mimango, Longjing, Dabaiyu Hongxiangyamango and Guixiang were resistant. No highly resistant or immune cuhivar was found.
