Other claims from this paper (7)
- Observation Seed germinability of green dragon ranged from 25 to 55% depending on seed source.
- Observation Neither the hard seed coat nor a water-soluble seed exudate was responsible for inducing or maintaining dormancy.
- Association Germination patterns appear to reflect the general climatic conditions at the sites of seed origin.
- Intervention effect Cold stratification at 3°C significantly increased relative germinability in all seed collections except the most southerly one from Baton Rouge.
- Observation The seeds from the southerly collection had a slower overall speed of germination.
- Intervention effect Germination of seeds from the most northerly site was promoted by cold stratification and occurred over a relatively brief period.
- Intervention effect Exposure to light changed the phenology of germination by promoting development of adventitious roots and primary leaves in the seedlings.
