- Observation Darkly staining granules are present among the bivalent chromosomes in late diakinesis in all members of Cucurbita.
- Observation Darkly staining granules among the bivalent chromosomes in late diakinesis are absent in Citrullus, Luffa and Cucumis.
- Observation Cucurbita pepo has twenty bivalent chromosomes.
- Observation Cucurbita maxima has twenty bivalent chromosomes.
- Observation Citrullus vulgaris has eleven bivalent chromosomes.
- Observation Luffa cylindrica has eleven bivalent chromosomes.
- Observation Cucumis melo has twelve bivalent chromosomes.
- Observation Cucumis sativus has fourteen chromosomes in the diploid cells.
- Observation Homologous chromosomes pass to the poles at anaphase with no evidence of lagging in Cucurbita pepo, C. maxima, Citrullus vulgaris, Luffa cylindrica and Cucumis melo.
- Observation The nucleolus tends to bud in both Luffa cylindrica and Cucumis sativus, and is often present after the spindle fibers appear in these species.
