摘　　要：This study was conducted to investigate ovule abortion of tetraploid Robinia pseudoacacia and its reasons. It was found that in the ovule development period of tetraploid R. pseudoacacia from 15 d after coronal opening, the levels of growth-promoting endogenous hormones in abortive ovules were lower than those in normal ovules, and the level of a growth-inhibiting hormone was always higher than those in normal ovules, indicating that ovule abortion of tetraploid R. pseudoacacia might be related to abnormal endogenous phytohormones in ovules. This study laid a foundation for further study on highly sterile phenomenon of tetraploid R. pseudoacacia seeds.探讨了四倍体刺槐胚珠败育现象及其发生原因,发现花冠展开15 d之后的胚珠发育期间,败育胚珠生长促进类内源激素水平低于正常胚珠,生长抑制类内源激素水平明显高于正常胚珠,表明四倍体刺槐胚珠败育也可能与胚珠内源激素异常有关。该研究为进一步研究四倍体刺槐种子高度不育现象奠定基础。
