前言柑桔类植物的病毒病,目前已引起世界各国的关注。White等(1934)研究了病毒在植物体分布的不均一性,得出顶端分生组织几乎没有病毒的结论,近年在很多植物的脱毒实践中均得到证实。Murashige(1972,1975)首先在柑桔类植物中运用茎尖嫁接技术,成功地获得了柑桔无病毒苗。无病毒苗不但生长旺盛,而且能提早结果。据报道,日前美国、西班牙等国已将此技术应用于生产。国内虽有过这方面的报道,但嫁接和移栽成活率都不理想。为此,
Preface The citrus plant virus disease has now caused the concern of all countries in the world. White et al. (1934) studied the heterogeneity of the distribution of the virus in the plant body and concluded that there is almost no virus in the apical meristem. In recent years, many plants have been verified in virus-free practices. Murashige (1972, 1975) first successfully used citrus virus-free seedlings by using shoot-tip grafting techniques in citrus plants. Virus-free seedlings not only strong growth, but also early results. According to reports, a few days ago the United States, Spain and other countries have applied this technology to production. Although there are reports in this area in China, the survival rates of grafting and transplanting are not satisfactory. to this end,
