研究了不同类型水稻剑叶气孔密度的差异及其与气体扩散阻力和比叶重的关系,结果表明:不同类型水稻气孔密度的差异极显著。籼×籼型>籼×粳偏籼型>籼×粳偏粳型>粳×粳型。同一类型不同品种间气孔密度的差异亦达到极显著水平。气孔密度与气体扩散阻力和比叶重均有极显著的线性负相关(r=-0.7240和-0.7657)。本文还探讨了通过籼粳稻杂交改善叶片质量的可能性。
The differences of stomatal density among different types of rice flag leaf and its relationship with gas diffusion resistance and specific leaf weight were studied. The results showed that there were significant differences in stomatal density among different types of rice. Indica × indica × indica × indica × indica × indica × japonica × japonica × japonica. Differences in stomatal density between different varieties of the same type also reached extremely significant levels. Stomatal density and gas diffusion resistance and specific leaf weight have a significant linear negative correlation (r = -0.7240 and -0.7657). This article also explored the possibility of improving leaf quality through indica-japonica hybridization.
