长期以来,人们普遍认为植物霜冻是由低温和植物的霜敏感性所决定,但难以圆满解释霜冻的多方面原因。自从发现冰核细菌以来,引起了人们的关注,世界上有美、日、中等多个国家,涉及10多个学科,对冰核细菌进行了全面系统的研究。近年来,国内外大量研究证明在自然界广泛存在着冰核活性 For a long time, it is generally accepted that plant frost is determined by the low temperature and frost sensitivity of plants, but it is difficult to satisfactorily explain the various causes of frost. Since the discovery of ice-core bacteria, it has aroused people’s attention. There are many countries in the world, including the United States, Japan and the Middle East. It involves more than 10 disciplines and conducted a comprehensive and systematic study on ice-nucleation bacteria. In recent years, a large number of studies at home and abroad have proved that ice nucleation activity exists widely in nature
