Abstract Different growth periods of epicuticular wax development on cabbage（Brassica oleracea
L. var. capitata L.） leaves were observed by scanning electron microscope，and types of wax mutant
and wild-type cabbage leaves were selected as materials．Results showed that some waxes crystals were
found in the wax mutant，the waxes crystals were immature and granular in the entire growth period．
Different structure of waxes crystals were found in the wild-type，granular and flaky were major crystals
structure at seedling stage，while cylindrical and flaky at head-forming stage，flaky and linear at
mature stage.
