Other claims from this paper (7)
- Observation Young lettuce anthers had no calcium precipitates.
- Observation After microspore mother-cell meiosis, calcium precipitates first appeared in tapetal cells.
- Observation At the late microspore stage, tapetal cells degenerated and their protoplasts moved with precipitates into the locule.
- Observation Calcium precipitates increased in early microspores and exine.
- Observation Calcium precipitates decreased when small microspore vacuoles fused into a large vacuole.
- Observation After the bicellular pollen grain large vacuole broke down, calcium precipitates reappeared in cytoplasm and then declined.
- Observation In mature pollen, most calcium precipitates were in exine and few in cytoplasm.
