一、研究种传植物病毒的意义 较早以前,人们认为病毒的种传问题远不及真菌、细菌等病原的种传普遍和重要,在植物病毒病的流行过程中不是主要因素。但隧着植物病毒学和种子病理学发展,及各种检测技术的改进和提高,已报道的种子传带病毒数量,和由种子带毒的植物种类和数量越来越大(见表)。种子传毒逐渐引起了植病、 First, the significance of research on plant-borne viruses Before long ago, people think that the problem of virus-borne viruses is far less than that of fungi, bacteria and other pathogens. It is not a major factor in the epidemic of plant virus diseases. However, the development of tunnel plant virology and seed pathology, the improvement and enhancement of various detection techniques, the reported number of seed-borne viruses and the species and number of plants poisoned by seeds have become larger and larger (see table). Seed poisoning has gradually caused the disease,
