Abstract:
OBJECTIVETo observe the pollen morphological differences among different populations of Changium smyrnioides.
METHODThe pollen morphology of 10 populations were examined through LM and SEM observations.
RESULTPollens in different populations were distinguished from each other in the size, the largest average size was the pollen of the population cultivated in Hongshan, and the smallest was that of the population cultivated in Jiuhuashan. Pollens were oval-shaped in all of the populations, and P/E values were around 1.5. Typical feature of surface ornamentation was stripe-like structure, different populations were distinguished from each other in the texture depth and the gap. With different length and width in different populations, typical feature of germinal aperture was nearly square and 3 germinal furrows. Variation with 4 germinal apertures were found in the pollen of population cultivated in Hongshan.
CONCLUSIONDiversity of pollen morphology was high, and differentiation was strong in Ch. smyrnioides.
