This chapter provides a summary of recommended germination test procedures and dormancy-breaking treatments for seeds of species within more than 70 families which have not been included in the previous chapters. Some caution may be needed when applying this information to diverse germplasm - see the comment on germination test prescriptions in Chapter 17. For several of the families listed here additional guidance on suitable dormancy-breaking treatments is available in Tables 17.1 and 17.2, Chapter 17.
The information in this chapter is not limited to those species showing orthodox seed storage behaviour: germination test procedures are also provided for species which are believed to exhibit recalcitrant seed storage characteristics. This is provided to assist both those handling recalcitrant seeds in short-term storage (moist and warm or cool environments), e.g. when collecting or transporting material, and those wishing to improve our knowledge of the physiology of these seeds with a view to increasing the periods for which they can be conserved. For more information on the recalcitrant seeds see the references listed in Chapter 1, Volume I.
