Other claims from this paper (19)
- Observation The species was found to have a distinct temperature optimum of between 15 and 20°C, and a minimum temperature for germination of approximately 2°C.
- Observation Short periods of exposure to high temperatures did not substantially affect germination performance.
- Observation Stratification greatly increased the range of temperatures over which a high proportion of the seed germinated.
- Observation Increases in the rate of germination with stratification are related to accrued thermal time during stratification.
- Observation Pre-imbibing seeds at water potentials down to -2 MPa increased the rate of germination; however, no advantage was found after pre-imibibing at -3 MPa.
- Observation Pre-imbibing seeds at water potentials down to -2 MPa increased the rate of germination; however, no advantage was found after pre-imibibing at -3 MPa.
- Observation This increased germination rate was associated with a shortening of the time to commencement of germination and more synchronous germination.
- Observation This increased germination rate was associated with a shortening of the time to commencement of germination and more synchronous germination.
- Observation Germination rate and germination capacity were impeded by soil matric potentials below -0.01 MPa, and germination was totally inhibited by soil matric potentials below -0.5 MPa.
- Observation Germination rate and germination capacity were impeded by soil matric potentials below -0.01 MPa, and germination was totally inhibited by soil matric potentials below -0.5 MPa.
- Observation Germination rate and germination capacity were impeded by soil matric potentials below -0.01 MPa, and germination was totally inhibited by soil matric potentials below -0.5 MPa.
- Observation Soil matric potential and temperature interacted in their effects on germination capacity, and seeds germinating at near optimum temperatures were less sensitive to soil moisture stress.
- Observation Soil matric potential and temperature interacted in their effects on germination capacity, and seeds germinating at near optimum temperatures were less sensitive to soil moisture stress.
- Observation Seeds survived dehydration within 60 h of the commencement of imbibition, but were increasingly affected by dehydration thereafter.
- Observation Seeds survived dehydration within 60 h of the commencement of imbibition, but were increasingly affected by dehydration thereafter.
- Observation The rate of imbibition was influenced by the ambient temperature and solution water potential.
- Observation At modest levels of water stress, imbibition was not impeded and the reduction in germination capacity was probably due to the inhibition of growth related processes.
- Observation At modest levels of water stress, imbibition was not impeded and the reduction in germination capacity was probably due to the inhibition of growth related processes.
- Observation Differences in germination response were detected between the seedlots and these could be related to the geographic origin of the seedlots.
