Abstract
柑橘系統性毒素病及似毒素病山帶病母樹經接穗傳播到苗木，而為害果樹生長影響本省柑橘生長頗大。早於1938年美國Fawcett為防治此類病害提倡健康母樹註冊辦法，近年來其他國家相繼推行無毒種苗制度。美國現今採用開放性多元辦法，由各州政府以單行法規推行柑橘無病種苗制度。我國目前仍採取保守性單元辦法，擬由立法（防疫決及種苗法）來規範推行，尚在規劃中。鑒於土地狹窄而嚴重之立枯病普遍傳播於全島各地，目前採用集約精密制；網室原原種庫一網室原種圃一網室採穗苗圃一網室鉢植育苗圃。本制度之執行基於各病毒病原已建立之血清生化速檢法、生物檢定法及病徵檢疫法等定期或不定期檢疫，健康苗種植田間後加予預防以避免再感染。
The systemic virus and virus-like diseases of citrus trees have been affecting the citrus industry considerably by causing great damage to citrus growth in Taiwan through pathogen-infected budlings derived from parent trees carrying the causal viruses. Fawcett initiated bud-wood certificate system by registration of healthy citrus parent trees in order to control the virus diseases as early as in 1938. The pathogen-free foundation stock and budling programs have been commonly performed in the other countries in recent years. The diversified system has been adapted at present in the United States as individual regulation for citrus bud-wood certificate program has been performed in each state government. However, a conservative policy has been performed in monopolistic way of pathogen-free stock and budling program before the establishment of plant protection and quarantine regulations in Taiwan. In view of the serious epidemic of citrus likubin on the narrow island, the intensified stock and budling production system was proposed as follows: foundation stock collection in screen house scion-production in screen house screen nurseries of potted budlings free of pathogen. The current system has been executed through periodical and prompt quarantine by serological and biochemical techniques, indexing with indicator plants and symptomological inspection. The pathogen-free budlings are well protected from reinfection according to the integrated measures of prophylaxis after transplating in the field.
