利用组织培养进行植物体的繁殖,对于采种困难或发芽力弱植物的繁殖;脱毒种苗的繁殖;杂种一代等遗传上尚未稳定的植物的繁殖和保持;以及有可能缩短育种年限等许多方面,都具有长处。目前,洋兰、草莓、康乃馨等作物已通过茎尖培养实现繁殖或脱毒种苗生产实用化。通过茎尖培养繁殖种苗,要经过许多熟练的作业才能完成,繁殖效率低。为了能够迅速繁殖育种中获得的优良个体,并大量、稳定和廉价地向生产提供优良种苗,日本农林水产省蔬菜茶叶试验场 The use of tissue culture for the reproduction of plants has been found to be of great use in the breeding of plants that are difficult to seed or germinate, the breeding of virus-free seedlings, the breeding and maintenance of genetically unstable plants such as hybrids, and the possible shortening of breeding years , All have strengths. At present, crops such as foreign blueberries, strawberries, carnations and so on have been put into practice through the shoot tip culture to produce breeding or virus-free seedlings. Cultivation of seedlings through the shoot tips, to go through many skilled operations to complete, breeding low efficiency. In order to be able to rapidly reproduce the fine individuals obtained in breeding and to provide excellent seedlings to the production in large quantities, steadily and inexpensively, the Japanese Ministry of Agriculture, Forestry and Fisheries Vegetable Tea Experimental Site
