Seedling performance in a trioecious cactus,Pachycereus pringlei: Effects of maternity and paternity

Plant Systematics and Evolution, 1999
We studied seed germination and the growth and survivorship of seedlings of females and hermaphrodites ofPachycereus pringlei (cardon), a Mexican columnar cactus whose geographically variable breeding system includes trioecy and gynodioecy. Results of a two-year field experiment conducted near Bahia Kino, Sonora, Mexico and a ten-month laboratory ...

Fertility islands around Prosopis laevigata and Pachycereus hollianus in the drylands of Zapotitlán Salinas, México

Journal of Arid Environments, 2008
Abstract The abundance of microorganisms in desert soil environments is closely related to the accumulation of resources around individual plants, called “islands of fertility”. This research was undertaken (1) to study the formation of islands of fertility in soils under Prosopis laevigata and Pachycereus hollianus in a preserved terrace and a ...

Geographic variation in the breeding system and the evolutionary stability of trioecy in Pachycereus pringlei (Cactaceae)

Evolutionary Ecology, 1998
The Sonoran Desert columnar cactus Pachycereus pringlei has a geographically variable, non-hermaphroditic breeding system. It is trioecious (separate males, females and hermaphrodites) in the northern two-thirds of its range in Sonora, Mexico, and in the southern three-quarters of its range in Baja California, Mexico, and is gynodioecious (separate ...

Peroxidase Activity in the Xerophytic «Cardon» (Pachycereus pringlei), a Cactaceae of the Sonoran Desert of Mexico

Journal of Plant Physiology, 1993
Summary Several isoperoxidase activities (EC 1.11.1.7. donor: H 2 O 2 oxidoreductase) were detected in branch extracts of the cardon cactus ( Pachycereus pringlei ) of the Sonoran Desert, Mexico. The whole enzyme activity in the crude extract was separated into several anionic and cationic isoenzymes.
