A dataset of the known species-specific seed viability constants estimated from the 'improved seed viability equation' of Ellis and Roberts (1980) .
viabilityconstants
A data frame with 7 columns:
A unique index
value, called by the vcindex argument in different functions.
The species for which the constants were estimated.
The species-specific moisture constant KE
The species-specific moisture constant CW
The species-specific temperature constant CH
The species-specific temperature constant CQ
Source of the data.
Primarily from Hong et al. (1996) , updated with more species. The source for each record is mentioned in the Reference column.
Various functions such as Sigma, StorageMC use
the viability constants from this dataset for computation through the
argument vcindex.
Viability constants derived from storage experiment at a single temperature are highlighted by "*" in species column. In such cases, CH and CQ are the universal temperature coefficients (0.0329 and 0.000478 respectively).
