摘 要: | This paper reports morphological differences between diploid, triploid, tetraploid, mixploid endosperm plants and the original diploid plants. In comparison with original diploids, the triploid, tetraploid and mixploid endosperm plants have larger stomas, greater variability in flowor organs, decreased fertility, decreased seed set per fruit, and a lot of abnormalities in chromosome behaviour in meiosis. The propagation of endosperm triploid seedless plants is in progress.
