Description of key information

Germination responses of fruits of lettuce (Lactuca sativa L.) to agar-agar containing different concentrations of heptanol were examined (Reynolds, 1977). Germination was estimated after 72 h.  EC50 was 85.84 mg/L, but the study is disregarded mostly for the use of an unsuitable test system for risk assessment purpose (Klimisch 3c).
