e0“Grains of the old conservative rice cv. Agamy (Sabini) were sown in greenhouse”
e6“Stigma receptivity was greatly affected by its age (the time elapsed since its emergence from the florets) and the proper age for stigmas to receive the pollen was one to two days”

Other claims from this paper (9)
- Intervention effect Pollen older than two hours gave a low grain set percentage in rice.
- Association Pollen viability in rice was greatly decreased as pollen age increased.
- Intervention effect Six and twelve hour pollen ages gave a considerable reduction in rice grain set percentage.
- Intervention effect Stigmas 1 or 2 days old gave the highest rice grain set percentage.
- Intervention effect Stigmas over 5 days old gave a comparably low rice grain set percentage.
- Observation The proper stigma age for receiving pollen in rice is one to two days.
- Intervention effect Pollination between 6 A.M. and 9 A.M. gave the high mean percent of grain set in rice.
- Intervention effect Pollination after 10 A.M. decreased the mean percent of grain set in rice.
- Association The reduction in grain set from late pollination reached its maximum at noon or later.
