Morphology and scarification of mesquite, huizache and bald cypress seeds
Tree population reduction and changes in structure and function of ecosystems are effects due overexploitation of dryland ecosystems such as woodlands, grasslands, and riparian systems. In addition, practically no information is available on reproduction and growth of these forest species. The objective of this study was to determine the germination rate and to describe seed morphology and embryo features of three indigenous species. Results indicate that seeds induced through mechanical pregermination treatment resulted in the highest germination rates for huizache (100 %) and mesquite (53 %). Montezuma bald cypress showed the higher germination (13 %) with the chemical treatment. Seed morphology was quite variable, being round shaped and smooth coated for huizache, rhombic shaped with rugged coat in mesquite, and prismatic with rugged coat for bald cypress, respectively. Seed size differed between species being greater for mesquite (47 mm2) and bald cypress (44 mm2), and lower for huizache (18 mm2).
