Abstract:
Taking flower of Hibiscus mitabilis L. as test material，the micro morphological structure in the early flowering period，flower bud period，full flowering period，and end flowering period were investigated by the scanning electron microscopy to reveal the accurate external and internal structure characteristics of Hibiscus mitabilis L. flowers.The results showed that，long handle trichomes were density，with component branch.The cells of calyx lower epidermis at 4 different periods arranged in neat rows and the cell surface was concave and convex.Pilose with long handle trichomes were less than the epidermis.Glandular hairs on flower early blooming stage were less，and more curl.In the flowering stage，there were no corolla piloses and glandular hairs on epidermis.There was only a small amount of short handle trichomes growing.The cell surface was uneven and polygon cells irregular.Corolla under the skin had no long handle trichomes，but had short stipitate glands.There was little change in cell morphology and cells arrange in neat rows.The mastoid cells of the stigma differentiated into multicellular trichomes.Cell morphology changed greatly in flower stage.And the differentiation of the mastoid cell was more obvious.The style was covered with trichomes，the style of the epidermis in the flowers early was sparse and short.But in the flower stage was dense and long.Style and stigma in the florescence and the end flowering were attached to a more pollen grains.The epidermal hair in the ovary in the flowers early was sparse and short.But in flower stage was dense and long.The ovule significantly increased in the early flowering more than in the flowering stage and the late flowering period.
