SUMMARY Variation in response to the Guignard pictate test may be detected within wild British populations of Brassica oleracea L. subsp. oleracea. Plants with the greatest reaction are the least frequent. In different seasons, individuals react differently to the test, possibly in response to temperature fluctuations. In B. oleracea the picrate test is perhaps responding to allyl derivatives of the glucosinolate sinigrin; HCN was not detected.
