In all of the 32 species studied the chromatin in one of the daughter nuclei produced by microspore division was found to diffuse earlier than the chromatin of the other. The former developed into a vegetative nucleus and the latter into a generative nucleus. The stage at which this difference between daughter nuclei was first found appeared to vary widely among species. The earliest was found to be at mid-anaphase observed inHemerocallis thunbergiiandMagnolia denudata, and the latest at early interphase observed inLilium japonicum, Pogonia japonicaandEpipactis thunbergii. InNarcissus jonquillaand 4 other species the nuclear differentiation started at late anaphase, inHaplopappus gracilisand 13 other species at early telophase, and inTradescantia paludosaand 7 other species at mid-telophase.
