近年台湾省北部受柑桔根线虫(Tylenchulus semipenetrans Cobb),南部受根腐线虫(Pratylenchus coffeae)为害严重,当前普遍使用的柑桔砧木——酸桔和广东(木黎)檬都感染线虫。台湾大学园艺系张喜宁三年来测试了该省33种芸香科植物对根腐线虫的抗性。结果表明,月桔、麻豆文旦×红文旦的杂交种具抗性,台湾扁实(木黎)檬×晚仑夏杂交种、 In recent years, Tylenchulus semipenetrans Cobb in the northern part of Taiwan and Pratylenchus coffeae in the south have been severely damaged. Commonly used citrus rootstocks, such as sour orange and Guangdong lemon (wood), are all susceptible to nematodes. Taiwan University Department of Horticulture Zhang Jining three years to test the province 33 kinds of Rutaceae root rot nematode resistance. The results showed that the resistance of Hybrids of Moonfruit, Madumandan × Red Wandan, Hybrids of Taiwan Plum (Muli) × Lunrangxia,
