HCN in Dutch and New Zealand white clover increased rather sharply after sunrise, reaching a maximum rather soon (e.g. after 4 h), then decreasing. This variation only occurred if the weather conditions of the successive days were much alike. Otherwise it was disturbed, often with a second maximum after noon. A maximum must be assumed for the night also. At least 50 leaves must be analysed.
These and other results seemed sufficient to start breeding research on HCN content in the Netherlands.
