The research for the embryo sac structure of triploid lines of SAR-2 showed that: 47% embryo sacs were normal and 53%were not. And in the latter, twin-ovules, twin-sacs, multi-eggs, multi-polar nuclei, multi-antipodal cells and non-egg apparatus were observed.5.
4．同源三倍体成熟胚囊的结构，观察结果表明：正常蓼型胚囊占47％，变异型胚囊占53％，在变异型胚囊中可观察到双胚囊、双胚珠、多卵、多极核、多群反足细胞团和无卵器分化等现象。
