Imbibition causes seeds to expand, which results in the seed coat or testa being broken. Seed germination begins with imbibition. Imbibition aids in the transport of water into the developing ovules. Imbibition is required during the first stages of root water absorption.

A mechanism for easily generating and organizing a collection of 
  seeds from a single seed, which may be subsequently used to ensure 
  reproducibility in processes/pipelines that utilize multiple random 
  components (e.g., trial simulation).

Analysis of seed germination data
    using the physiological time modelling approach. Includes functions
    to fit hydrotime and thermal-time models with the traditional approaches
    of Bradford (1990) <doi:10.1104/pp.94.2.840>
    and Garcia-Huidobro (1982) <doi:10.1093/jxb/33.2.288>. 
    Allows to fit models to grouped datasets,
    i.e. datasets containing multiple species, seedlots or experiments.

Seed vigor is defined as the sum total of those properties of the seed which determine the level of activity and performance of the seed or seed lot during germination and seedling emergence.  Testing for vigor becomes more important for carryover seeds, especially if seeds were stored under unknown conditions or under unfavorable storage conditions. Seed vigor testing is also used as indicator of the storage potential of a seed lot and in ranking various seed lots with different qualities. The vigour index is calculated using the equation given by (Ling et al. 2014) <doi:10.1038/srep05859>.

An inspectable and composable workflow for search-and-replace in text
    files. Files can be listed, filtered, and searched separately, with
    inspectable exclusions showing what was excluded and why. Matches are
    represented as structured vectors that can be printed with context,
    summarized, and filtered. Replacements can be defined at search time or set
    and updated after the search. Only matches present in the vector are modified 
    when files are written. Backup and restore helpers are provided for file 
    workflows. Text that has already been read can also be searched and updated 
    directly, giving users control over input, output, and encoding when needed.
