The Ecological Significance of Clonal Growth in the Understory Tree, Pawpaw (Asimina triloba)
We evaluated three possible functions of clonal growth related to genet persistence in the root-suckering understory tree pawpaw, Asimina triloba (L.) Dunal: (1) risk spreading through multiplication of stems, (2) enhanced establishment and survival of new stems, and (3) horizontal expansion growth of patches. The number, diameter growth, and spatial distribution of annual stem recruits were ex...
متن کاملAnnonacin in Asimina triloba fruit: implication for neurotoxicity.
INTRODUCTION The acetogenin, annonacin, from the tropical annonaceous plant Annona muricata, is a lipophilic, mitochondrial complex I inhibitor reported to be more toxic than rotenone to mesencephalic neurons. The temperate annonaceous plant Asimina triloba (pawpaw) is native to the Eastern United States and products are available online. This study determined whether annonacin is in the pawpaw...
متن کاملSeed mass, seedling size and neotropical tree seedling establishment
1 We examined amongand within-species effects of seed mass for seedling establishment from seed to 5 years of age in a field experiment at Paracou, French Guiana. 2 Six seeds of each of eight species were weighed and planted into each of 120 plots (1 m 2 ) throughout closed-canopy forest along 12 100-m transects in 1998. 3 We described the microhabitat of each planting site using principal comp...
متن کاملExperimental Native Tree Seedling Establishment for the Restoration of a Mexican Cloud Forest
The cloud forests of Mexico have been degraded and severely fragmented, and urgently require restoration. However, progress with restoration has been constrained by a lack of information concerning the seedling ecology of native tree species. An experiment was therefore conducted to assess the influence of different environmental factors on the seedling survival and growth of four native tree s...
متن کاملIdentification of annonaceous acetogenins in the ripe fruit of the North American pawpaw ( Asimina triloba ).
The North American pawpaw [ Asimina triloba (L.) Dunal] is a tree fruit in the early stages of commercial production in the United States. This plant contains annonaceous acetogenins in the twigs, unripe fruit, seeds, roots, and bark tissues, which display antitumor, pesticidal, antimalarial, anthelmintic, piscicidal, antiviral, and antimicrobial effects, suggesting many potentially useful appl...
