Vigour testing can be found in literature as early as 1876 when Nobbe described it as “Triebkraft” a German word meaning “Driving Force”. Scientists have long searched for a way to describe the differences amongst seed lots with comparable germination. Numerous tests, theories and methodologies have been used to test for and describe seed vigour.

Seed vigour is defined by ISTA as “the sum total of those properties of the seed which determine the level of activity and performance of the seed of seed lot during germination and seedling emergence. Seeds which perform well are termed ‘high vigour’ seeds (Perry, 1978).

SEED VIGOUR TESTS
Any seed vigour test must be able to provide a more sensitive index of seed quality than the germination test and provide a consistent ranking of seed lots in terms of their potential performance. It must also be objective, rapid, simple and economically practical, reproducible and interpretable. Internationally many vigour tests have been proposed. Some have gained wide acceptance (for example the cold test for Zea mays L. and the conductivity test for Pisum sativum L.), while others have been proved of value in a local context only (within country). Unfortunately some tests have inherent procedural or interpretation problems and fail to meet the requirements of a vigour test.
After many years of comparative vigour testing, the ISTA Vigour Test Committee has conc1uded that vigour tests which consistently rank seed lots in terms of their potential performance in the field and/or in storage can be standardised. Single tests based on some aspect of germination behaviour (e.g. the accelerated ageing and cold tests) along with the conductivity test show the most promise for this purpose. The primary objective of such tests is to indicate to the seed purchaser, or seed store manager, whether or not trouble may be expected from a high germinating seed lot if the lot is placed under environmental stress in the field, in storage or during transit. These tests do not produce a planting or storage index. Such indices are not possible because of the complexity and variability of factors involved in any planting/storage environment.
Vigour testing methods are published in the ISTA Handbook of Vigour Test Methods. These are recommendations only, and are not yet inc1uded in the ISTA Rules for Seed Testing. The ISTA Vigour Test Committee will introduce a Vigour Testing Chapter into the Rules once ISTA is satisfied that results are consistently reproducible among seed testing laboratories.
