The development of acceptable vigor tests is a challenging goal. Unlike germination testing, there is n
one standard test against which the merits of a vigor test can be judged. Part of this difficulty arise
from the perception that no universal seed vigor test exists. Presently, most vigor tests available ar
recommended for a specific crop. It seems that one central theme should be to reduce the range of vigo
tests and focus standardization efforts on those that appear to have the broadest crop application. Nex
the optimum times and procedures for each crop need to be determined and specified.
