| Abstract: | The pollen morphology characteristics of Ardisia crenata Sims,A.hypargyrea C.Y.Wu et C.Chen and A.japonica(Thunb.) Blume in Yunnan Province were observed by optical microscopy and electron microscopy.And A.hypargyrea C.Y.Wu et C.Chen was examined for the first time.Results showed that the pollen of Ardisia is a single grain,triangular-shaped class of spherical.It is classified different poles and bilaterally symmetry.It is a three sides slightly concave spherical if we saw it from equatorial plane,while is ... |
