Other claims from this paper (14)
- Observation About 80 days before emergence the flower was about 0.3 cm long and enclosed by two tightly rolled stipules.
- Observation During the rapid elongation stage of the leaf petiole the flower entered a slow growth period 40 to 60 days before emergence.
- Observation Spathe color development started about 28 days before emergence, when the flower was about 50% of emergence length.
- Observation At flower emergence the spathe, excluding the lobes, was about 75% red.
- Observation The lobes did not reach full redness until 7 to 10 days after emergence.
- Observation Peduncle growth was sigmoidal with maximum growth rate 21 days after emergence.
- Observation The young, growing subtending leaf blade had a negative net photosynthetic rate.
- Intervention effect Removing the young growing subtending leaf blade advanced flower emergence by 18 days.
- Intervention effect Removing the soft green leaf (25 to 30 days old) advanced flower emergence by 11 days.
- Intervention effect Removing the mature subtending leaf had little effect on flower emergence.
- Observation The mature subtending leaf had the highest net photosynthetic rate.
- Observation Flower growth resumed after the subtending leaf blade unfurled and had a positive photosynthetic rate.
- Mechanism The subtending leaf appears to supply nutrients needed by the developing flower.
- Mechanism Leaf removal accelerated flower emergence, probably by shortening the slow growth phase of the flower.
