Relating to or capable of producing cyanogen or cyanide compounds through natural or chemical processes.
From cyanogen + -etic (relating to). The suffix -etic means 'relating to' or 'of the nature of' in scientific terminology.
Cyanogenetic plants contain glycosides (sugar-based compounds) that break down into cyanide only when the plant is damaged or chewed—it's a clever chemical bomb triggered by injury.
