Resumo: | Kudzu is a cover crop that has escaped cultivation in some subtropical and warm temperate regions. Kudzu has previously demonstrated broad intraspecific physiological plasticity while colonizing new environments. The objective of this paper was to investigate characteristics of kudzu leaflet anatomy that might contribute to its successful growth in climatically distinct environments, and to escape cultivation as well. Fresh and fixed leaflet strips of field-grown plants were analyzed. The lower epidermis of kudzu showed a higher frequency of stomata (147 ± 19 stomata mm-2) than the upper epidermis (26 ± 17 stomata mm-2). The average number of trichomes per square milimeter was 8 for both the upper and the lower epidermis. The average trichome length was 410 ± 200 mm for the upper epidermis and 460 ± 190 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, two layers of palisade parenchyma and one layer of spongy parenchyma. One layer of paraveinal mesophyll was found between palisade and spongy parenchyma. In conclusion, leaflets of kudzu present anatomical characteristics that might contribute to the broad physiological plasticity shown by kudzu. |

Kudzu tem demonstrado ampla plasticidade fisiológica quando coloniza novos ambientes. Este trabalho teve por objetivo investigar características da anatomia foliar de kudzu que poderiam contribuir para seu hábito invasivo e também para sua propagação em ambientes distintos do ponto de vista climático. Foram analisados cortes frescos e permanentes de lâminas foliares de plantas crescidas no campo. A epiderme inferior tipicamente apresentou maior freqüência de estômatos (147 ± 19 estômatos mm-2) do que a epiderme superior (26 ± 17 estômatos mm-2). O número médio de tricomas por milímetro quadrado foi 8 para ambas, epiderme superior e epiderme inferior. O comprimento médio dos tricomas foi 410 ± 200 mm para a epiderme superior e 460 ± 190 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 parênquima paliçádico e uma camada de parênquima lacunoso. Uma camada de mesófilo paranerval foi encontrada entre os parênquimas paliçádico e lacunoso. Concluindo, folíolos de kudzu apresentam características anatômicas que podem contribuir para a ampla plasticidade fisiológica demonstrada pela espécie.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNetto, Adaucto Bellarmino de PereiraGabriele, Antonio CarlosPinto, Hilton Silveira1999-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5372Pesquisa Agropecuaria Brasileira; v.34, n.8, ago. 1999; 1361-1365Pesquisa Agropecuária Brasileira; v.34, n.8, ago. 1999; 1361-13651678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5372/2564info:eu-repo/semantics/openAccess2010-07-14T16:55:07Zoai:ojs.seer.sct.embrapa.br:article/5372Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-14T16:55:07Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
