Normal-looking seeds are listed in the second column, with `normal endosperm' having at least 16 endosperm nuclei and embryo stages ranging from 1-cell to pre-globular (preglob). The majority of seeds in this class were at the 8- and 16-cell stages. Mutant seeds are listed in the third and fourth columns and fall into two categories. One category includes seeds with 2-8 endosperm nuclei; the other includes seeds without any endosperm. In both categories of this mutant seed class, embryo stages range from 1- to 8-cell,with the majority at the 4- and 8-cell stage. ϰ2 tests were performed to compare the `normal endosperm' class or the `no endosperm' class between glc and glc mea-1.
