摘要/Abstract

摘要： 以三系杂交稻汕优63为对照，比较研究表明，具有超级杂交稻模式株型的培矮64S/E32有以下生理优势。（1）叶面积指数前期较小，中期稳健，后期衰减缓慢、维持较高水平；（2）抽穗后剑叶和倒2叶的比叶重显著或极显著大于对照；（3）后期上3叶叶绿素含量衰减缓慢，变化平稳；（4）上3叶单位叶面积气孔数目比对照多19.2%，达极显

Abstract: Looking back at the history of rice breeding, two breakthroughs resulted largely from identification and utilization of dwarfing genes in 1960s and the wild abortive cytoplasmic male sterility (CMS) in 1970s had significantly raised rice yield potential. But the yield potential of both inbred and hy
