对于作物的真菌和细菌病害,用化学农药防治多可见效;而对于病毒病很少或不见效果。近年在组织培养和热处理的综合运用上得到了脱去病毒的亲本材料,为病毒病的防治找到了一个新的解决途径。 1952年,莫锐和马丁用分生组织顶端培养获得了脱去病毒的大理花子株,受到科技界的重视,但当时的技术尚未完善。现在已知对有病毒的亲本材料通过分生组织顶尖培养可获得无病毒材料,还有利用原
For crop fungal and bacterial diseases, the use of chemical pesticide control can be more effective; and for the virus disease with little or no effect. In recent years, the comprehensive utilization of tissue culture and heat treatment has been off the virus of the parent material, for the prevention and treatment of viral diseases to find a new solution. In 1952, Morrie and Martin obtained the de-virus Dali flower-like strain by cultivating the top of the meristem, which attracted the attention of the scientific and technological circles. However, the technology was still not perfect at that time. It is now known that virus-free parental material can be obtained via virus-free material via meristem culture,
