研究一个简捷、准确、可行的白叶枯抗性测定的方法,是生产所急需。近年利用离体叶片段法筛选防治白叶枯病的有效药剂方面,有过报道。本文的目的则是探索离体叶片段法测定水稻对白叶枯病的抗性,现将试验结果简报如下。 一、试验材料 试验用的菌株是1982年从珠江三角洲采集并鉴定的各菌群的代表菌株。供试品种选自国内、日本和IRRI常用的鉴别品种。 二、试验方法 A simple, accurate and feasible method for the determination of resistance to bacterial leaf blight is urgently needed. In recent years, the use of in vitro leaf segment screening of effective agents to control bacterial blight, have been reported. The purpose of this paper is to explore the in vitro leaf segment method for the determination of rice resistance to bacterial blight, the test results are summarized below. First, the test material test strains used in 1982 from the Pearl River Delta collected and identified strains of each representative strain. The test varieties are selected from domestic, Japan and IRRI common identification varieties. Second, the test method
