- Germinación de semillas y clave para la identificación de plántulas de seis especies arbóreas nativas de humedales del sureste de México Luis Felipe Zamora-Cornelio Susana Ochoa-Gaona Georgina Vargas Simón Jorge Castellanos Albores Bernardus H.J. de Jong Biología wetlands Germination native trees riverine vegetation seedling morphology Seed germination and key to seedling identification for six native tree species of wetlands from Southeast Mexico. Wetland tree species are of importance for economic and restoration purposes. We describe the germination process and seedling morphology of six arboreal native species typical of Southeastern Mexico: Annona glabra, Ceiba pentandra, Pachira aquatica, Haematoxylum campechianum, Coccoloba barbadensis and Crataeva tapia. A total of 300 seeds per species were planted in a mixture of sand, cocoa plant husk and black soil (1: 1: 1), and maintained in a tree nursery with 30% artificial shade, from February to November of 2007. We carried out the morphological characterization, and elaborated a key to seedlings based on: 1) germination type 2) seedling axis and 3) leaf elements. P. aquatica has cryptocotylar hypogeal germination, the others have phanerocotylar epigeal germination. Germination rates were high (>86%), except for C. barbadensis (69%). Rev. Biol.
