AbstractThis study was undertaken to examine changes in the content of pigments and accumulation of metals from vehicular pollution in selected species of roadside trees under vehicular pollution. A major arterial road with heavy vehicle emissions in the Kumasi Metropolis was designated as the polluted site, while Kwame Nkrumah University of Science and Technology Campus was designated as the control site. Four tree species (Terminalia catappa, Mangifera indica, Ficus platyphylla and Polyalthia longifolia) selected for the study were well distributed and abundant in the polluted and control sites. Photosynthetic pigments and levels of heavy metals (Pb, Cu, Cd and zinc) were assessed in their leaves. Chlorophyll and carotenoid contents were determined by absorption spectrometry, while the metal accumulation index (MAI) was used to determine the total metal accumulation capacity of the tree species. We observed a reduction in photosynthetic pigments in the leaf samples from the polluted site. Ficus platyphylla had the maximum reduction in total chlorophyll (49.34%), whereas Terminalia catappa recorded the lowest reduction (33.88%). Similarly, the largest decrease (31.58%) of carotenoid content was found in Terminalia catappa trees and the lowest in Polyalthia longifolia (16.67%). The Polyalthia longifolia, Ficus platyphylla and Terminalia catappa leaf samples collected at the polluted site recorded a higher ratio of chlorophyll a/b. Heavy metal (Cu, Pb, Zn and Cd) accumulation in leaf samples was higher in the polluted site than in the control, as expected. The highest metal MAI value was recorded in Mangifera indica (5.35) followed by Polyalthia longifolia with 4.30. The findings from this study specifically demonstrate that air contamination induced by vehicles decreases the level of photosynthetic pigments in trees subjected to roadside emissions. It is clear that both chlorophyll a/b and chlorophyll/carotenoid ratios will act as very useful stress-level markers. Elevated heavy metal levels in the tree species along arterial roadsides indicate that they serve as heavy metals sink. The change in MAI resulting from different pollution burden is an indication that the removal capabilities of the tree species differ from each other. We therefore suggest M. indica and P. longifolia as potential species to be used in air pollution reduction plans in the city.

Stem Leaf

Assimilate distribution in Lupinus angustifolius was studied during 7 weeks after emergence of the main inflorescence by feeding [14C]urea to a single leaf or group of leaves on a plant and measuring 14C in plant parts 24 h after feeding. Nine times of feeding were involved, each with 14C treatments encompassing leaves of the main stem and first-order laterals. The inflorescence was a minor sink for assimilates compared with root, main stem and developing lateral shoots. During the first 4 weeks the inflorescence relied on main stem leaves, especially the upper leaves, but in the fifth week leaves of upper laterals became principal sources of assimilates. The transition occurred after four to six basal fruits had set, and just as upper flowers were commencing to abscise. Estimates were made of transfer of photosynthetically fixed carbon from the uppermost main stem leaf to the inflorescence, using data on carbon dioxide exchange and changes in carbon content of this leaf and its translocatory commitment to the inflorescence as determined by 14C feeding. Assimilate flow from leaves to flowers was confined largely to organs of the same or adjacent orthostichies (2/5 phyllotaxis), but these affinities became less definite during fruiting. Import of 14C by reproductive units was related to phenology, position on an inflorescence, and accumulation of dry matter. All flowers attracted assimilates strongly at the bud stage but lost sink strength progressively after opening. Upper flowers destined to abscise failed to import assimilates or to bleed from phloem for several days before being shed. Lower flowers which set fruits showed a rapid resurgence of sink strength once their corollas had senesced and the young fruits had commenced to elongate.

A silvicultura urbana compreende todas as atividades relacionadas a implantação e manejo da vegetação presente nas cidades, podendo ocorrer nos espaços verdes públicos ou privados e proporciona diversos benefícios socioambientais. O objetivo do trabalho foi identificar a ocorrência de espécies frutíferas utilizadas na alimentação de seres humanos e avifauna em 4 bairros e 11 praças do município de Santarém, Pará, através do inventário total destas áreas, considerando somente os indivíduos com altura igual ou superior a 1,5m. Foram calculadas a Frequência absoluta (FR) e Frequência relativa (FR) de cada espécie alimentar em relação ao número total de indivíduos inventariados. Quanto à origem das espécies, foram classificadas como exóticas ou nativas. Além disso, utilizando o método de revisão de literatura, foram apontadas características acerca do tamanho e peso dos frutos. Foram contabilizados 1646 indivíduos arbóreos, distribuídos em 63 espécies de 31 famílias botânicas. Sendo classificadas como frutíferas de capacidade alimentícia para humanos e/ou avifauna 660 indivíduos, de 22 espécies pertencentes a 10 famílias, com destaque para a Mangueira (Mangifera indica L.), Oitizeiro (Licania tomentosa), Jambeiro (Syzygium malaccense), Castanhola (Terminalia catappa), Cajueiro (Anacardium occidentale) e Goiabeira (Psidium guajava) com maior número de representantes. Desta forma, é possível afirmar que a arborização no município de Santarém é composta por 40,09% de espécies frutíferas alimentares à população e avifauna local.

Neste trabalho foram reconhecidas 87 morfoespécies de árvores, arvoretas e palmeiras nos sete parques urbanos de Recife, com a observação de 2808 exemplares. As espécies de árvores e arvoretas mais abundantes foram Clitoria fairchildiana, Mangifera indica, Tecoma stans, Terminalia catappa e Tabebuia impetiginosa. Entre as palmeiras destacaram-se Dypsis lutescens, Roystonea oleracea, Cocos nucifera, Acrocomia intumescens e Elaeis guineensis. A maior abundância foi verificada no Parque Treze de Maio, com 981 exemplares e 58 espécies. O Parque da Jaqueira apresentou 773 indivíduos e 68 espécies, sendo o parque com maior riqueza de espécies. O parque menos arborizado e com menor riqueza florística foi o Robert Kennedy, com 122 indivíduos e 18 espécies, e os que apresentaram piores condições de densidade foram Arraial Novo do Bom Jesus e Santana (41,7 e 56,7 indivíduos/ha, respectivamente). O potencial paisagístico da flora local foi mal aproveitado nos parques urbanos de Recife, privilegiando-se o plantio de espécies exóticas ou nativas de outros biomas brasileiros. As densidades de árvores, arvoretas e palmeiras foram consideradas baixas em quatro dos sete parques, que precisam receber novos plantios de espécies arbóreas, preferencialmente nativas, contribuindo para amenização climática e conservação e valorização de flora nativa.

Áreas verdes são espaços livres na cidade que devem possuir algum tipo de vegetação e tendem a assumir funções social, estética, ecológica, educativa e psicológica. A arborização urbana caracteriza-se como um dos elementos mais importantes que compõem o ecossistema das cidades e parte dessa arborização envolve as praças da cidade. Picos é uma cidade que apresenta temperaturas altas o ano todo e espaços públicos, como suas praças, são uma alternativa para proporcionar bem-estar para a população em geral. Deste modo, este estudo objetivou realizar um inventário das plantas arbustivo-arbóreas existentes em cinco das principais praças do município de Picos-PI, considerando: riqueza e abundância de espécies, fitossanidade, origem fitogeográfica e presença de plantas tóxicas. Um total 252 indivíduos vegetais foi levantado, distribuídos em 35 espécies e 17 famílias botânicas. As cinco espécies de maior ocorrência foram Ixora coccinea, Azadirachta indica, Adenanthera pavonina, Terminalia catappa e Duranta repens, representando 62,69% da comunidade estudada, sendo a praça Antenor Neiva a de maior riqueza de indivíduos. Na relação entre riqueza e abundância de espécies, verificou-se 7,2 indivíduos/espécie. Com relação à origem fitogeográfica, identificou-se 51% de espécies exóticas e 49% de nativas. A análise da fitossanidade mostrou que 95,23% das árvores encontram-se em boas condições, sem apresentar danos visíveis. Quanto à presença de plantas tóxicas ou comprovada atividade alergênica, indicou-se as espécies Thevetia peruviana, Duranta repens e Mangifera indica, as quais podem representar algum risco para as pessoas que frequentam as praças.

Mycorrhizal occurrence was tested in roots of 24 terrestrial and epiphytic orchid species growing at the Lankester Botanical Gardens (Cartago, Costa Rica). Standard staining and light microscopy were used to search for pelotons. Roots in contact with the substrate harbor extensive mycorrhyzal fungi. There may be a wide distribution and density of the fungal flora in the secondary forests of the site, this could explain the high natural regeneration of orchids on the garden.
