The idea was tested by Karine Lopes as part of her PhD in geography at the Federal University of Jata\u00ed (UFJ) in Goi\u00e1s. \u201cSome farmers use seed balls made of soil, but there were previously no biodegradable capsules,\u201d she says. The team planted seeds of <em>Dipteryx alata<\/em>, <em>Anadenanthera colubrina<\/em>, and <em>Enterolobium maximum<\/em>, all trees native to the Cerrado biome, some in the capsules and others not. In the processed cardboard capsules, the germination rates were 97% (<em>D. alata<\/em>), 42% (<em>A. colubrina<\/em>), and 12% (<em>E. maximum<\/em>), compared to 15%, 21%, and 8% respectively when planted directly in the soil. The hope is that capsules spread by drones will help with reforestation. The project was presented at the National Aviation Congress in Cuiab\u00e1, Mato Grosso, in July, and the researchers are awaiting the outcome of negotiations between the Federal University of Rondon\u00f3polis and mining company Vale to continue the research in the municipality of Mariana, Minas Gerais, which was devastated by the collapse of the Fund\u00e3o dam in 2015 (<a href=\"https:\/\/abori.com.br\/ambiente\/capsulas-com-sementes-de-arvores-nativas-podem-auxiliar-na-restauracao-ecologica-do-cerrado\/\" target=\"_blank\" rel=\"noopener\"><em>Ag\u00eancia Bori<\/em><\/a>, October 18).<\/p>\n","protected":false},"excerpt":{"rendered":"Biodegradable tree seed capsules made of cardboard and starch improve germination","protected":false},"author":475,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[206,213,200,243],"coauthors":[785],"class_list":["post-556141","post","type-post","status-publish","format-standard","hentry","category-notes","tag-biodiversity","tag-botany","tag-environment","tag-innovation"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/556141","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=556141"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/556141\/revisions"}],"predecessor-version":[{"id":556142,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/556141\/revisions\/556142"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=556141"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=556141"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=556141"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=556141"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
