Kinetics of the Natural Evolution of Hydrogen Cyanide in Plants in Neotropical Pteridium arachnoideum and its Ecological Significance [PDF]

Journal of Chemical Ecology, 2005
The time-dependent natural release of hydrogen cyanide (HCN) was studied quantitatively using young croziers of the neotropical bracken fern Pteridium arachnoideum. HCN production was quantified in crushed tissue using a flow reactor at 30.0 +/- 0.1 degrees C. Released HCN was carried into appropriate traps with a moist air flow.

Growth and mortality patterns of the Neotropical bracken (Pteridium arachnoideum) and their response to shading in a savanna–riparian forest transition

Flora, 2019
Abstract Although certain clonal species are often overdominant in disturbed tropical ecosystems, it is often unclear how this success is related to their patterns of clonal growth and how they respond to abiotic heterogeneity. Here we describe ramet growth and survival in an overdominant Neotropical bracken fern (Pteridium arachnoideum) and assess ...

Woody vegetation structure of Brazilian Cerrado invaded by Pteridium arachnoideum (Kaulf.) Maxon (De

Flora - Morphology, Distribution, Functional Ecology of Plants, 2011
Abstract Biological invasion is one of the major components of global change. In the Brazilian Cerrado, the fern Pteridium arachnoideum (neotropical bracken) is a potentially invasive species which is expected to change the vegetation structure of savannas. We assessed effects of the dominance of P.

Phenolics and condensed tannins of high altitude Pteridium arachnoideum in relation to sunlight exposure, elevation, and rain regime

Biochemical Systematics and Ecology, 2007
Abstract Non-adapted plants growing in high altitude such as bracken fern Pteridium arachnoideum are exposed to environmental extremes that may induce a chemical adaptive response. Here we show that there is a non-uniform distribution of low (LMP) and high molecular weight (HMP) phenolics in the frond parts of P.

Comparative dynamics of ptaquiloside and pterosin B in the two varieties (caudatum and arachnoideum) of neotropical Bracken Fern (Pteridium aquilinum L. Kuhn)

Biochemical Systematics and Ecology, 1995
Abstract Significant chemical differences have been observed among the two neotropical varieties of bracken, caudatum and arachnoideum . Trans - o -hydroxycinnamic acid and coumarin have been found only in the caudatum variety. The concentration changes of ptaquiloside and pterosin B with blade growth were markedly different in caudatum and ...
