Soil quality. Biological methods. Chronic toxicity in higher plants has-hardcopy Reverse gain1 Scope This International Standard describes a method for determining the inhibition of the growth and reproductive capability of higher plants by soils under controlled conditions. Two species are recommended: a rapid cycling variant of turnip rape (Brassica rapa CrGC syn. Rbr) and oat (Avena sativa). The duration of test should be sufficient to include chronic endpoints that demonstrate the reproductive capability of the test plants. By using
