Chloroplast ultratructure and 77K fluorescence emission spectra of lemmas and flag leaves in rice
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.
