摘　　要：甘蔗健康种苗系指通过种茎温汤处理或腋芽茎尖培养等方法脱去甘蔗体内病菌的腋芽试管苗或种茎及其无性繁殖种茎苗,以及在不同隔离条件下逐代繁育并符合标准的原原种、原种和生产用甘蔗种苗。在生产甘蔗健康种苗过程中,利用间歇浸没式生物反应器(TIBs)进行甘蔗健康种苗的快繁,提高了增殖系数,降低了工作量。"甘蔗健康种子"的新技术,大大减少了甘蔗种植的用种量,并有利于机械化操作,降低了甘蔗种植成本。Sugarcane healthy seedlings or seedcanes are those sterilized by hot water treatment or axillary shoot tip culture, including axillary plantlets, asexual seedcanes for propagation or commercial production, which are produced under strict isolation conditions and meet certain criteria. In recent years, a temporary immersion bioreactors system（TIBs）has been developed and applied, which speeds up the multiplication of the healthy seedlings, improves the multiplication coefficient, and reduces the labor requirement. More recently, a new technique so-called ‘Plene’ has been developed, which substantially reduces the seedcane rate, and is good for mechanical operation so reducing the planting cost.
