Potential versus actual seed performance ― can vigour testing provide an answer ?

Abstract

(...) It is argued that the whole direction of international vigour testing research needs to be reevaluated with a greater emphasis placed on the need to understand the variables and assumptions involved in each test. It appears increasingly unlikely that any one test, whether germinative, physiological or biochemical, will be appropriate for even a single species under all conditions. Thus there is a need to consider more carefully development work on promising tests within a local context
