本文运用细胞地理学原理,根据 Gregor 的实验方法,探讨了杉木核型地理变异与表型变异的相关性。结果表明杉木染色体组有一定的地理变化模式,染色体相对长度对地理变异敏感,种子千粒重与核型地理变异相关显著。结果初步表明方法是可行的。 In this paper, using the principle of cell geography, according to Gregor’s experimental method, the relationship between the geographical variation of Chinese fir and phenotypic variation was discussed. The results showed that the Chinese fir genome had a certain geographical variation pattern, the relative length of the chromosome was sensitive to the geographical variation, and the 1000-grain weight was significantly correlated with the karyotype variation. The results show that the method is feasible.
