Effect of gut passage and dung on seed germination and seedling growth: donkeys and a multipurpose mesquite from a Mexican inter-tropical desert.

摘要: We address the idea that donkey's gut passage and dung could increase seed germination seedling growth of Prosopis laevigata. This species is a useful plant in Mexican inter-tropical desert, where land use change habitat fragmentation are currently affecting P. laevigata shrublands. conducted greenhouse experiments which seeds ingested by donkeys non-ingested were placed pats or soil. Results suggested did not have significant effects on germination. On other hand, significantly increased height dry weight seedlings. Information about establishment be used to promote natural regeneration this species.
