Morphologic Characters of Microspores in Female and Male Kiwi Fruit Plants (Actinidia Arguta) during the Development of Floral Organs
In order to study the mechanism of microspore sterility of kiwi fruit, 7-year-old kiwi fruit plants (Actinidia arguta) were used as materials and the microspore characters of female and male plants during the development of floral were observed, by optical microscope, TEM and SEM. In male plants, the pollens developed normally, with obvious columellae on the spore extine and integrated organelles, which microspores developed mitotically into mature binucleate pollens. In female plants, pollens were sterile, without columellae on the spore extine, moreover, the boundary lines of organelles were vague definition. Microspores were at the stage of single nucleus without mitosis. The pollen protoplasm of female plants concentrated into a paste, closed to one side and then disappeared, resulting in cavities in the pollen and pollen abortion. In conclusion, pollens of female plants had microspores during the development of floral organs, however, abnormal development presented at later stage of signal nucleus, leading to pollens abortion.
