据日本北海道大学农学部教授木村郁夫1993年1月27日报道,日本国北海道立中央农业试验场玉田哲男主任研究员率领的研究小组在世界上首先阐明了甜菜的难病——丛根病的发病机理,从而把利用基因控制技术发明的免疫剂进行接种后,很好地抑制了丛根病的发生。丛根病的危害不仅在北海道,而且在欧美及中国也普遍发生,所以可以说此项研究成果具有国际价值。 According to a report made by Professor Kimura Yukio of Hokkaido University on January 27, 1993, a research team led by researcher Yu Tianzhe of Japan’s Central Hokkaido Prefectural Agricultural Experimental Laboratory has first elucidated the hard cause of beet Mechanism, and thus the use of genetic control technology invented immunization agent vaccination, very good inhibition of rhizomania. Rhizomatosis is not only harmful in Hokkaido, but also in Europe, the United States and China, so it can be said that the research is of international value.
