Leaf Anatomy and C02 Recycling During Crassulacean Acid Metabolism in Twelve Epiphytic Species of Tillandsia (Bromeliaceae)
Int. J. Plant Sci. 154(1): 100-106. 1993. © 1993 by The University of Chicago. All rights reserved. 1058-5893/93/5401 -0010502.00 LEAF ANATOMY AND C02 RECYCLING DURING CRASSULACEAN ACID METABOLISM IN TWELVE EPIPHYTIC SPECIES OF TILLANDSIA (BROMELIACEAE) VALERIE S. LOESCHEN,* CRAIG E. MARTIN,' * MARIAN SMITH,t AND SUZANNE L. EDERf •Department of Botany, University of Kansas, Lawrence, Kansas 66045-2106; and t Department of Biological Sciences, Southern Illinois University, Edwardsville, Illinois 62026-1651 The relationship between leaf anatomy, specifically the percent of leaf volume occupied by water- storage parenchyma (hydrenchyma), and the contribution of respiratory C02 during Crassulacean acid metabolism (CAM) was investigated in 12 epiphytic species of Tillandsia. It has been postulated that the hydrenchyma, which contributes to C02 exchange through respiration only, may be causally related to the recently observed phenomenon of C02 recycling during CAM. Among the 12 species of Tillandsia, leaves of T. usneoides and T. bergeri exhibited 0% hydrenchyma, while the hydrenchyma in the other species ranged from 2.9% to 53% of leaf cross-sectional area. Diurnal malate fluctuation and nighttime atmospheric C02 uptake were measured in at least four individuals of each species. A significant excess of diurnal malate fluctuation as compared with atmospheric C02 absorbed overnight was observed only in T. schiedeana. This species had an intermediate proportion (30%) of hydrenchyma in its leaves. Results of this study do not support the hypothesis that C02 recycling during CAM may reflect respiratory contributions of C02 from the tissue hydrenchyma.

ELBS Newsletter JULY 2017
NEWS East London LETTER Bromeliad Society July 2017 South Africa Established: 25 July 2009 Our aim is to promote and encourage awareness and interest in Bromeliads in East London and all of South AfricaAfrica!!!! ELBS is an Affiliated Society of Bromeliad Society International June Meeting And now for something completely different! We met at the home of Wyndham Whitfield who very kindly opened his home, garden and orchid houses to us to explore and enjoy. Due to his recent experience with the poisoning of the water hyacinth on the Nahoon River from where he gets his water, I was surprised to see that some beauties have survived, but not without a lot of hard work being involved plus repotting and the pain of having to let go all the orchids that did not survive. It truly was a devastating experience for Wyndham. Wyndham gave a very interesting talk on orchids, an overview of where they originally come from and the main types plus some crosses, which I would not even try to name here, so enjoy the photos of just a few samples of Wyndham’s orchids and Our host, Wyndham Whitfield with those of you who know about them, some of his gorgeous orchids. will no doubt recognise the beauties pictured here. He a l s o covered what is basically required a n d which are the most suitable to grow in our East London climate. Everyone has always told me that cymbidiums were so easy to bring into flower here, but sometimes our night time temperatures don’t go down low enough. -
Catalogue of the Vascular Epiphytic Flora of Uruguay
Acta Botanica Brasilica doi: 10.1590/0102-33062019abb0059 Catalogue of the vascular epiphytic flora of Uruguay Patricia Mai1* , Andrés Rossado2 , José Mauricio Bonifacino2,3 and Jorge Luiz Waechter4 Received: February 21, 2019 Accepted: June 17, 2019 . ABSTRACT We provide an updated list of the vascular epiphytic flora occurring in native environments of Uruguay based on literature review, herbarium specimens, and fieldwork throughout the country. The catalogue provides standardized information for each species, including accepted name, synonyms used within Uruguay, epiphytic category, distribution within the country, habitat, conservation status, observations, and a voucher citation. The effort documented 73 species for the epiphytic flora of Uruguay (3 % of the flora), distributed among 29 genera and 12 families. Bromeliaceae was the richest family (17), followed by Polypodiaceae (16) and Orchidaceae (12). Tillandsia stood out as the most speciose genus with 15 species. Characteristic holoepiphytes was the most diverse ecological category. More than half of the epiphytic species documented for Uruguay (53 %) reach their southernmost geographic distribution in the country, whereas only two mostly epipetric species of Tillandsia — T. arequitae and T. uruguayensis — are endemic to the country. Almost half of the epiphytic species found are presently under categories of threat of extinction, with 60 % of them occurring in national protected areas. Both the richest epiphytic families and the predominance of characteristic holoepiphytes coincide with findings from floristic and ecological studies previously carried out in humid subtropical regions. Keywords: conservation status, epiphytic category, geographic distribution, hemiepiphytes, holoepiphytes, subtropical forests, Uruguay, vascular epiphytes The most recent estimation of vascular epiphytes in the Introduction world reports 27,614 species, distributed in 73 families and 913 genera. -
Air-Pollutant-Philic Plants for Air Remediation
Journal of Environmental Protection, 2012, 3, 1346-1352 1 http://dx.doi.org/10.4236/jep.2012.310153 Published Online October 2012 (http://www.SciRP.org/journal/jep) Air-Pollutant-Philic Plants for Air Remediation Misa Takahashi, Hiromichi Morikawa Department of Mathematical and Life Sciences, Graduate School of Science, Hiroshima University, Higashi-Hiroshima, Japan. Email: [email protected] Received July 23rd, 2012; revised August 24th, 2012; accepted September 19th, 2012 ABSTRACT In this communication, we review our work over two decades on air-pollutant-philic plants that can grow with air pol- lutants as the sole nutrient source. We believe that such plants are instrumental in mitigating air pollution. Our target air pollutant has been atmospheric nitrogen dioxide (NO2), and our work on this subject has consisted of three parts: Varia- tion in plants’ abilities to mitigate air pollutants among naturally occurring plants, genetic improvement of plants’ abili- ties to mitigate air pollutants, and the plant vitalization effect of NO2. So far, an estimation of the half-life of nitrogen derived from NO2 uptake in plants belonging to the 217 taxa studied to date has shown no plants to be naturally occur- ring air-pollutant-philic. However, we found that an enormous difference exists in plants’ ability to uptake and assimi- late atmospheric NO2. Future studies on the causes of this process may provide an important clue to aid the genetic production of plants that are effectively air-pollutant-philic. Both genetic engineering of the genes involved in the pri- mary nitrate metabolism and genetic modification by ion-beam irradiation failed to make plants air-pollutant-philic, but mutants obtained in these studies will prove useful in revealing those genes critical in doing so. -
Cultivo De Tillandsia Geminiflora Brongn. Em Diferentes Substratos(1)
NOTA Cultivo de Tillandsia geminiflora Brongn. em diferentes substratos(1) MARIA ESMERALDA SOARES PAYÃO DEMATTÊ(2) e ULA VIDAL(3) RESUMO Tillandsia geminiflora é uma bromélia pouco cultivada no Brasil, mas com potencial para exportação. Para cultivo de bromélias, o xaxim entrava na composição de substratos, até a proibição desta prática. A substituição do xaxim por outros materiais com propriedades semelhantes tem sido pesquisada, e o objetivo deste trabalho foi comparar o desenvolvimento de T. geminiflora em substratos à base de componentes vegetais (xaxim, fibra de coco e casca de Pinus). As observações foram feitas por cerca de dois anos. Casca de coco pura proporcionou os melhores resultados. Palavras-chave: bromélias, xaxim, fibra de coco, casca dePinus . ABSTRACT Cultivation of Tillandsia geminiflora Brongn. in different growing media Tillandsia geminiflora is little grown in Brazil, but has good potential for exportation. Tree fern fiber was used in mixtures for bromeliad cultivation until the prohibition of this practice. The replacement of tree fern by other materials with similar properties has been researched. Thus, and the aim of this study was to compare the development of T. geminiflora grown in media with different vegetal components (tree fern, coconut husk and pinus bark). Plant development was evaluated for about two years. Pure coconut bark husk gave the best results. Keywords: bromeliads, tree fern fiber, coconut husk, pinus bark. 1. INTRODUÇÃO A base para a preparação de substratos para bromélias no Brasil foi, durante muito tempo, o xaxim (ANDRADE T. geminiflora (Figura 1), uma bromélia epífita, ocorre e DEMATTÊ, 1999), retirado de Dicksonia sellowiana no Brasil, no Paraguai e na Argentina. -

Water Relations of Bromeliaceae in Their Evolutionary Context

With 2 figures Think tank: water relations of Bromeliaceae in their evolutionary context JAMIE MALES* Department of Plant Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EA, UK Received 31 July 2015; revised 28 February 2016; accepted for publication 1 March 2016 Water relations represent a pivotal nexus in plant biology due to the multiplicity of functions affected by water status. Hydraulic properties of plant parts are therefore likely to be relevant to evolutionary trends in many taxa. Bromeliaceae encompass a wealth of morphological, physiological and ecological variations and the geographical and bioclimatic range of the family is also extensive. The diversification of bromeliad lineages is known to be correlated with the origins of a suite of key innovations, many of which relate directly or indirectly to water relations. However, little information is known regarding the role of change in morphoanatomical and hydraulic traits in the evolutionary origins of the classical ecophysiological functional types in Bromeliaceae or how this role relates to the diversification of specific lineages. In this paper, I present a synthesis of the current knowledge on bromeliad water relations and a qualitative model of the evolution of relevant traits in the context of the functional types. I use this model to introduce a manifesto for a new research programme on the integrative biology and evolution of bromeliad water-use strategies. The need for a wide-ranging survey of morphoanatomical and hydraulic traits across Bromeliaceae is stressed, as this would provide extensive insight into structure– function relationships of relevance to the evolutionary history of bromeliads and, more generally, to the evolutionary physiology of flowering plants. -
