Abstract

Ficus americana and F. obtusifolia are among the most important tree species in Seasonally Dry Tropical Forests (SDTF) due to their evergreen condition and high levels of biomass. However, the SDTF of Lambayeque and northern Peru is greatly diminishing due to the advance of migratory agriculture, illegal mining, and deforestation. The objective of this work was to study the taxonomic aspects of both species, as well as seed germination, micropropagation, and in vitro germplasm conservation. Seed germination was 100% for both species up to three months after collection. As for micropropagation, rooting, and germplasm conservation, the Piper culture medium was effective, as it was constituted by MS mineral salts with 0.02 mg.L-1 IAA and 0.02 mg.L-1 GA3. In vitro germplasm conservation lasted more than 24 months for both species. Acclimatization under greenhouse conditions reached 50% survival for both species.

美洲榕的微繁与种质保护。和来自秘鲁兰巴耶克(Lambayeque)的F. obtusifolia Kunth

美洲榕树(Ficus americana)和钝叶榕树(F. obtusifolia)因其常绿条件和高生物量而成为季节性干燥热带森林(SDTF)中最重要的树种。然而，由于迁移农业、非法采矿和森林砍伐的发展，兰巴耶克和秘鲁北部的SDTF正在大大减少。本工作的目的是研究这两个物种的分类学方面，以及种子萌发、微繁和离体种质资源保存。采集后3个月，两种植物的种子萌发率均为100%。在微繁生根和种质保存方面，Piper培养基是由0.02 mg的MS矿物盐组成的。L-1 IAA和0.02 mg。l - 1赤霉素。两种植物的离体种质保存时间均超过24个月。在温室条件下驯化，两种植物的存活率均达到50%。

期刊介绍： Colombia Forestal Journal publishes original manuscripts on themes of the forest field and various aspects of natural resources and the environment, which are discriminated in the categories of research article, review, reflection and technical notes of agreement with the stipulations of COLCIENCIAS for scientific publications. According to the classification of scientific areas of the Organization for Economic Cooperation and Development (OECD), Colombia Forestal Journal belongs to the large area of Agricultural Sciences (4), Agriculture, Forestry and Fisheries (4A) and to the discipline Forestry (4A02). Since its creation in 1978, the journal has been edited and published by the Francisco José de Caldas District University with headquarters in Bogotá. The quality of the content of the journal has been strengthened with the collaboration of national and international external evaluators in a double blind arbitration system and the dissemination has been extended by publishing manuscripts in a language different from Spanish and with inclusion in bibliographical databases such as Scopus. , DOAJ, Scielo, Redalyc, Ebsco, CAB Abstracts of CAB International, Forestry Abstracts, Ulrich''s, Latindex, Publindex. Likewise, it has academic profiles at Mendeley, Academia and Researchgate. The articles that are submitted to Colombia Forestal Journal must be original and unpublished and have not been postulated in other journals.
