柑桔裂皮病是由柑枯裂皮病类病毒(Citrus exocortis viroid,CEV)引起的病害,它的主要症状是砧木韧皮部纵向裂皮,鳞片化剥落,植株矮化,生长缓慢。因为症状有无十分明显,故病树和未发病树肉眼可辨,无需再作其它诊断。实践上的困难在于多数带有类病毒的慢性感染植株在什么条件下发病?如何预测?能否预防?因此,本研究特以慢性感染树作对照,与病树进行同工酶的对比研究。寻找发病的先兆,以期找到早期诊断的参考指标,并为进一步研究病害的预防打下基础。
Citrus split disease is a disease caused by citrus exocortis viroid (CEV). Its main symptom is the longitudinal splitting of the phloem of the rootstock, scale exfoliation, plant dwarf, and slow growth. Because of the obvious or not, the diseased tree and the diseased tree can be discerned without any further diagnosis. In practice, the difficulty lies in the conditions of most chronic infection with virus-like virus in what condition? How to predict? Can prevent? Therefore, this study special chronic infected tree as a control, and diseased trees for isoenzyme comparison study. Looking for signs of onset, in order to find a reference indicator for early diagnosis, and to lay the foundation for further study of disease prevention.
