| Abstract: | Pollen sub-micronmorphology of 22 species and 2 varieties belonging to 8 gen-eras of Rosaceae were observed under Scanning Electron Micsoscope,the pollen grains of whichare prolate and subprolate,and with 3-colposate ,the exine sculptrue are lirae and tectum punc-ture,and the pollen grains size and fine morphology of exine sculpture vary with differentspecies.According to the difference of fine morphology of exine sculPture,three gubtypes are recog-nized:1.with lirae and tectum puncture on the surface of pollen;2 only with lirae on the surface ofpollen;3 with tectum puncture on the surface of pollen,lirae being irregular. |
