| 摘 要： | 用双波长（550,488nm）显微分光光度法以测定籽粒发育时期不同Su2基因剂量（0-3）玉米杂交种（Mo17×B73）胚乳核的DNA含量。结果表明：单个胚乳核的DNA含量在授粉后第8天是3.0-4.6C，10天以后迅速上升，20-22天达到高峰，为48.9-63.9C，然后下降。年份间DNA含量差异显著（P≤0.05）。在籽粒发育过程中，胚乳核DNA含量与籽粒

| Abstract: | A two-wave length (550-488nm) microspectrophotometric method was employed to measure Feulgen Stained corn endosperm nuclei of four isogenetic genotypes (B73×Mo17). The mean DNA content per nucleus in centrally lacated endosperm averaged between 3.0 and 4.6C (C=haploid content) at 8 days after polli |
