Resumo: Tropical kudzu (Pueraria phaseoloides Benth, Leguminosae-Faboideae) has been established in southeastern Brazil in a region characterized by the transition between subtropical and tropical biomes. The seasonal changes in temperature and water availability found in this region are very distinct from those found in the region where tropical kudzu is native. The objective of this paper was to describe characteristics of leaflet anatomy related to water and energy balance in tropical kudzu. The lower epidermis of tropical kudzu showed a higher frequency of stomata (213 stomata.mm-2) than the upper epidermis (101 stomata.mm-2). Trichomes were present in both lower and upper epidermis. The average number of trichomes per square millimeter was 9 for the upper epidermis and 13 for the lower epidermis. The average trichome length was 300 mm for the upper epidermis and 460 mm for the lower epidermis. Cuticle thickness was not considerably different between lower and upper epidermis. The leaflet blade consisted basically of two layers (upper and lower) of unicellular epidermis and two layers of both palisade and spongy parenchyma. One layer of paraveinal mesophyll was found between palisade and spongy parenchyma.

Puerária foi também introduzida na região sudeste do Brasil, região esta caracterizada pela transição entre os climas tropical e subtropical. Este trabalho teve como objetivo descrever algumas das características da anatomia foliar de puerária relacionadas á economia de água e energia. A epiderme inferior apresentou maior frequência de estômatos (213 estômatos.mm-2) quando comparada à epiderme superior (101 estômatos.mm-2). O número médio de tricomas por milímetro quadrado foi 9 para a epiderme superior e 13 para a epiderme inferior. O comprimento médio dos tricomas foi de 300 mm para a epiderme superior e 460 mm para a epiderme inferior. A espessura da cutícula não diferiu significativamente entre as epidermes inferior e superior. A lâmina foliar consistiu basicamente de duas camadas de ambos, parênquima paliçádico e parênquima lacunoso. Uma camada de mesófilo paranerval foi encontrada entre os parênquimas paliçádico e lacunoso.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNetto, Adaucto Bellarmino de PereiraGabriele, Antonio CarlosPinto, Hilton Silveira1997-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4705Pesquisa Agropecuaria Brasileira; v.32, n.7, jul. 1997; 689-693Pesquisa Agropecuária Brasileira; v.32, n.7, jul. 1997; 689-6931678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/4705/7329info:eu-repo/semantics/openAccess2015-02-24T18:41:56Zoai:ojs.seer.sct.embrapa.br:article/4705Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-02-24T18:41:56Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
