随着植物病理学研究的进展,寄主与病原物关系已进入到定量研究的新时期。著名的植物病毒学家王鸣歧教授1982年11月在兰州讲学时提出:“生物学已进入定量研究的时期,要向研究物理、化学那样定量”。表达了当前植物病理学研究的新特点。在定量研究植物病害时,难于解决的是定量接种。其难点有二:一是难于准确的在植株上接一定菌量。其次是无法检查接种到植株上病原菌孢子数。我们从研究小麦慢叶锈性的需要出发,在1982、1983两年探索叶锈菌定量是接种方法,用“植株直接定量接
With the progress of plant pathology, the relationship between host and pathogen has entered a new era of quantitative research. Well-known plant virologist Professor Wang Mingqi in Lanzhou in November 1982 lectures put forward: “Biology has entered a quantitative research period, to study the physical and chemical as quantitative.” Express new features of current plant pathology research. In the quantitative study of plant diseases, it is difficult to solve the quantitative vaccination. The difficulty is twofold: First, it is difficult to accurately determine the amount of bacteria in the plant. Second is the inability to check the number of spores of pathogens inoculated onto the plants. We start from the study of wheat leaf rust needs, in 1982 and 1983 to explore leaf rust quantitative method of inoculation, with "direct quantitative
