Abstract:
Taking normal-yield and low-yield Camellia oleifera trees as materials，pollen vitality was measured by iodine-potassium iodide solution，pollen tube growth in style was observed with fluorescent microscope after aniline blue dyeing，and paraffin-embedded sectioning technique was adopted to observe the development of abnormal embryo sac.Meanwhile，fruit setting data of natural pollination and cross pollination were collected to analysis the mechanism of blossom and fruit drops.The results showed that both the pollen vitality and the growth rate of the pollen tube of normal-yield C.oleifera trees were better than that of the low-yield one.The ovariance analysis showed fruit setting rate had a remarkable correlation to different sampling trees，yet had no correlation to pollination methods.Both of the two characteristic trees developed female gametophytes，compared with the normal-yield trees，abnormal and degenerated female gametophyte were more apt to appear in low-yield trees，which led to deformed ovule and serious blossom and fruit drops.
