Genetic diversity in populations of Maytenus dasyclada (Celastraceae) in forest reserves and unprotected Araucaria forest remnants

摘要: ABSTRACT Understanding the genetic structure and diversity of plants is fundamental to their conservation permits sustainable use by local communities. Th e genus (Celastraceae) composed possessing Maytenus pharmacological antioxidant properties. However, economic properties species M. dasyclada , a typical Araucaria forests in Brazil Uruguay, have been little studied. In this work, natural populations located unprotected preserved forest remnants were investigated using RAPD isozymes markers. results demonstrated that areas preservation, possess relatively high degree polymorphism values for Na, Ne, Shannon index, He Ho, indicating variability. Moreover, these protected are very close each other potentially experience signifi cant gene fl ow. presented here highlight relevance preservation
