Pawpaw [Asimina triloba (L.) Dunal] Fruit Ripening. I. Ethylene Biosynthesis and Production
Pawpaw fruit ethylene production, 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (ACS) and ACC oxidase (ACO) activities, and tissue content of the ethylene precursor ACC and conjugate malonyl-ACC (MACC) were measured during postharvest ripening. Fruit were harvested near the advent of the ripening process and were ripened at room temperature. The fruit displayed increases in ethylene prod...
متن کاملPawpaw [Asimina triloba (L.) Dunal] Fruit Ripening. II. Activity of Selected Cell-wall Degrading Enzymes
Pawpaw fruit were harvested at the advent of the ripening process and were ripened at room temperature. Based on fruit fi rmness and respiration and ethylene production rates at harvest and during ripening, fruit were classifi ed into one of four categories: preripening (no to very slight loss of fi rmness; preclimacteric), early ripening (some softening; increasing rates of ethylene and CO2 pr...

متن کاملAutonomous Shoot Production in Pawpaw (asimina Triloba (l.) Dunal) on Plant Growth Regulator Free Media
North American pawpaw [Asimina triloba (L.) Dunal] is a temperate climate member of the Annonaceae used as an ornamental and specialty tree fruit crop. Micropropagation could provide a clonal propagation method for plant production and contribute to germplasm preservation. A pawpaw culture was established that has produced shoot-bud clusters for over six years when maintained on a plant growth ...
متن کاملThe 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...
