Preliminary results found that both apparently healthy scion and diseased scion grafted on Mexican lime exhibited the symptoms of tristeza disease, such as veinclearing, water-soaking, stem-pitting and smaller leaves on lime.Under this study It is not unusual vein-corking was found in older leaves. When these two different scions were grafted on lemon, the symptoms of seedling yellows were shown after 2-3 months. Therefore, it could be sure that tristeza virus exhibits in both healthy-appearance citrus trees and diseased-appearance citrus trees in Taiwan. It was also found that most newly developing leaves from diseased scions is different from that of apparently healthy scions. In advanced observations, these newly developing leaves of the former showed the symptoms resembling the deficiency of iron or manganese element after 3-4 months. It alse showed severe yellowing, stunting and smaller leaves. The symptoms of micro-element deficiency were more clearly when the diseased scions were grafted noto Valencia species. The dieased plant that called Huanglungpin may suggest the presence of another agent, probably greening disease, in addition to seedling yellows-tristeza. |
