Abstract:

The HCN content of dried Acaciafarnesiana foliage varies from 0.0 to 5.495 tlmol/g among individuals within a population (XC = 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 J,tmol/g) in Santa Rosa National Park, Guanacaste Province, Costa Rica. The correlation coefficient of H CN 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.
