1 前 言 在山东省,由于马铃薯生长正处于温度高、气候干旱的季节,所以植株病毒性退化速度非常快。退化严重时可引起减产80％。研究和实践证明,茎尖培养脱毒是解决这一问题的有效途径。马铃薯脱毒及速繁技术是现代生物技术中的主要研究内容之一。也是生物技术在生产中应用最早、最广泛、效果最显著的研究成果之一。脱毒技术研究及脱毒种薯的推广,使马铃薯的种植面积、产量、品质及
1 INTRODUCTION In Shandong Province, because of potato growth in a season of high temperature and arid climates, the rate of plant virus degradation is very high. Severe degradation can cause 80% reduction in production. Research and practice have proved that tip culture detoxification is an effective way to solve this problem. Virus detoxification and rapid propagation of potato technology is one of the major research topics in modern biotechnology. Biotechnology is also one of the earliest, most extensive and most effective research results in production. Research on virus-free technology and popularization of virus-free seed potato make the planting area, yield, quality and
