The experiment was performed under laboratory conditions, and the extracts used were: leaf aqueous extract, leaf ethanolic extract, leaf hydroalcoholic extract 70:30, leaf hydroalcoholic extract 50:50, bark from the stem aqueous extract, bark from the stem ethanol extract, bark from the stem hydroalcoholic extract 70:30 and bark from the stem hydroalcoholic extract 50:50. All E. dysenterica leaf and bark from the stem extracts exerted inhibitory effects on the radicle and hypocotyl growth of black-jack seedlings.

In greenhouse, germination of seeds under their soil of origin and under vermiculite was analyzed. The seeds from igapo presented higher mean weight and thickness compared to the floodplain seeds, which, on occasion, presented higher averages of length and width. The seed germination percentage of both environments was similar, but the speed was higher for the igapo seeds, regardless of the substrate. The igapo seeds are larger than the floodplain seeds and, because they have more reserves, they are able to produce more vigorous seedlings, regardless the physical conditions of the substrate.","PeriodicalId":54998,"journal":{"name":"Iheringia Serie Botanica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91019964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
