| Somatic and zygotic embryos from mature seeds of rauli-beech, Nothofagus alpina (Poepp. & Endl.) Oerst., were encapsulated in different artificial endosperms in order to generate a cover that fulfills the function of nourishment and protection of the embryos, facilitating their later germination. The content of sodium alginate varied by 4%, 3%, and 2%, as did the immersion time in calcium chloride (CaCl2), which acts as complexing agent. The artificial endosperm components of the Murashige and Skoog medium (MS) were added, supplemented with 0.5 mg L-1 indolacetic acid (IAA), 0.5 mg L-1 naphthaleneacetic acid (NAA), 2 mg L-1 6-benzylaminopurine (BAP) and 30 g L-1 sucrose. The germinative behaviors of encapsulated somatic and zygotic embryos were... |
