本文对沈农265和汕优63两个水稻(Oriza sativa L.)品种的稃片和旗叶叶绿体超微结构,低温荧光特性进行了比较研究.结果表明:水稻的稃片具有发育良好的叶绿体,在高产品种中,稃片和旗叶叶绿体的发育程度比对照品种好,而且基粒类囊体的垛叠更规则.通过低温荧光发射光谱分析表明:两个品种中稃片的F 685/F 734值均比旗叶高,因此,在稃片中激发能较多地分配给PSII.最后,本文讨论了稃片可能在提高水稻的产量中发挥其重要作用.

The chloroplast ultrastructure and photosynthetic characteristics of lemmas and were studied using electron microscopy and 77K fluorescence emission spectrophotometer.The results showed that the lemma possessed well developed chloroplasts and regularly stacked grana thylakoids.And, the value of fluorescence emiss higher than that of the flag leaves, indicating that the lemmas might play an important role in improving the yield potential of rice.
