Recalcitrant seeds : a status report including a bibliography 1979-87
Many plantation crops, fruit trees, and timber species have "recalcitrant" seeds - those that perish when moisture contents are reduced below a certain level, in contrast to "orthodox" seeds, which can tolerate desiccation and freezing temperatures.

Abstract
This report summarizes technical knowledge concerning the characteristics and identification (often difficult) of recalcitrant seeds, their moisture content, the sensitivity to desiccation and chill of various seed types, and methods of seed storage. A concluding discussion of priorities for research covers the need for: a sampling and moisture test, new methods of seed identification, determination of the causes of seed deterioration, and new storage techniques, especially through cryopreservation of embryos. A 5-page list of references and an 8-page international bibliography (unannotated) for the years 1979-87 are appended.
