本文介绍了甘蔗腋芽快繁种苗的关键技术。该技术与常规的幼叶组织培养快繁种苗技术相比 ,具有简化工序、节约原料、降低成本、所得蔗苗健壮、繁殖速度快、变异小等优点 ,因此是目前甘蔗良种快速繁殖的重要手段。同时 ,结合自己在这方面的工作实践提出一些粗浅的认识。 This paper introduces the key technologies of sugar cane axillary buds fast propagation. Compared with the conventional technique of rapid propagation of young leaf tissue culture, the technique has the advantages of simple process, raw material saving, cost reduction, robustness of the obtained seedling, rapid propagation and small variation, and is therefore important for rapid propagation of sugarcane seeds at present means. At the same time, I put forward some superficial understanding based on my work practice in this field.
