一、概况植物辐射敏感性的研究是辐射生物学的一个重要课题,它对于了解辐射的生物学作用,对于辐射在农业中的应用,都有重要意义。这方面早期的研究主要集中在各植物类群间敏感性的差异方面。如 Johnson(1936)对50个科的100多种植物所作的研究,Sparrow 等(1957)对100多种植物在γ田里进行连续六年的观察,Osborne 等(1961)对120种、500多个品种的试验,就是几个著名的例子。大量研究证明,植物的辐射敏感性不但取决于它们在分类学上 I. Overview The research of plant radiation sensitivity is an important issue in radiation biology. It is of great significance to understand the biological role of radiation in the application of radiation in agriculture. Earlier studies in this area have focused mainly on the differences in sensitivity among various plant species. For example, in a study by Johnson (1936) on more than 100 species in 50 families, Sparrow et al. (1957) observed more than 100 species of plants in the gamma field for six consecutive years. Osborne et al. (1961) evaluated 120 species and more than 500 A variety of experiments, is a few famous example. Numerous studies have shown that plant radiation sensitivity depends not only on their taxonomy
