Chlorophyll Accumulation in Leaves of Rice Pollen Albinos
Zhang Yu-lin and Wang Zhen-gui
In contrast to the green plantlets, rice pollen albinos contain a little chlorophyll only, and the relative contents of protochlorophyll (ide) and carotenoids comparing with chlorophyll are much higher however. The contents of chlorophyll and related pigments in leaves of pollen albinos vary regularly with the variation of light regimes. The spectra of regenerated albinos from pollen albinos possess the same characteristics as described above, but their pigment contents are lower. It is likely that the occurrence of these characteristics of pollen albinos may be attributed to their deficiency of plastid membrane system and the latter in turn may be the result plastom mutation. In view of the variation of pigment contents among different planoets of the same variety, it is resonable to deduce that plastids of pollen albinos are heterogeneous structurally and functionally.
