Hydrothermal time germination models for radiata pine (Pinus radiata D. Don)
(Cambridge University Press, 2009-08)
The objective of this study was to fit a hydrothermal germination model to germination data for a seedlot of radiata pine (Pinus radiata D. Don). Seeds were incubated for 50 d at constant temperatures and water potentials ...
Key features of the seed germination response to high temperatures
(John Wiley & Sons, Inc. on behalf of the New Phytologist Trust, 2012-10)
The responses of seed germination rates (GRs) and final germination percentages to soil temperature follow trends similar to those for many plant processes. There is an optimum temperature for seed germination (Tₒ), which ...
Modelling seed germination in response to continuous variables: use and limitations of probit analysis and alternative approaches
(Cambridge University Press, 2014-07-07)
Probit-based models relating a proportional response variable to a temporal explanatory variable, assuming that the times to response are normally distributed within the population, have been used in seed biology for ...
Comparison of three different statistical approaches (non-linear least-squares regression, survival analysis and Bayesian inference) in their usefulness for estimating hydrothermal time models of seed germination
(Cambridge University Press (CUP), 2020-05-01)
Hydrothermal time (HTT) models describe the time course of seed germination for a population of seeds under specific temperature and water potential conditions. The parameters of the HTT model are usually estimated using ...
