The ...The structures and shapes of variance ornamentals plant's pollens in several families (Leguminosae, Rosaceae, Iridaceae and Oleaceae) were investigated by using scaning electron microscope (SEM). The results were as follows:(1) The pollens of Leguminosae (Cercis chinensis Bunge,Wisteria sinensis (Sims) Sweet, Robinia pseudoacacia L.) were almost round and had three holes,and the scale were between 29~33μm×18~23μm,and their outside wall were orange surface;(2) Rosaceae including Prunus persica (L.) Batsch f.rubro plena Schneid, Pyracantha fortuneana (Maxim) L.,Rosa multiflora Thunb had similar pollen form such as elipse and three holes and long marrow stripe surface but showed different scales (between 38~61μm×33~19 μm); (3) Oleaceae including Syringa oblata Lindl. had representative characters such as round ball pollen 34(±0 5)μm×23(±0 5)μm with three splits and meshed lines surface,and large and thick mesh without regular polygon;(4) Iridaceae,including Iris pseudocorus L. and Iris japonica Thunb.both had one hole and their scales were about 54~105μm×45~65μm besides the significant difference of their pollen forms and wall surface lines,and Iris japonica Thunb. had particular characters such as mesh lines, overlarge mesh, thick mesh dorsal, white and roundish protrusion. Furthermore, evolutions on the four families were explored in this paper.Read More
