Abstract

The HCN content of dried Acaciafarnesiana foliage varies from 0.0 to 5.49 μmol/g among individuals within a population ( $X$ = 1.80, s.d. = 1.80 in wet season; $X$ = 1.21, s.d. = 1.27 in dry season; n = 26) and increased in the wet season (average difference of 0.59 μmol/g) in Santa Rosa National Park, Guanacaste Province, Costa Rica. The correlation coefficient of HCN values for 26 bushes in the wet and the dry season was 0.898, suggesting that the seasonal change was proportional to the amount of HCN present in the foliage of each bush.

Variation of cyanogenesis in some plant species of the midwestern United States
1996, Biochemical Systematics and Ecology
The frequency of cyanogenesis of 48 species of vascular plants was examined by testing 30 individuals from five populations of each species for release of cyanide. The rate at which cyanide was released and the amount of cyanide released varied widely among individuals of a population and among populations of a species. For many taxa, the frequency of cyanogenesis was highly variable among populations. Of the species examined, 20 have not been reported previously as being cyanogenic.
