摘要：
Detailed studies were made on changes in the quantity of 1.4 MDa rRNA precursor in barley and wheat cultivars with different degrees of frost tolerance. When analysing genotypes with different LT(50) values a close negative correlation was found between the quantity of 1.4 MDa molecular mass rRNA precursor and the frost tolerance of the given barley or wheat cultivar. The results suggest that a technique based on low temperature phosphorus incubation at the seedling stage could be suitable for the selection of genotypes on the basis of this character in applied research.
