“…Sin embargo, cuando se trabaja con datos históricos, la falta de registros cronológicos completos es muy frecuente, lo que puede resultar en la obtención de intervalos de tiempo de muy distinta duración. En esos casos, es válido asumir que existieron otros eventos de floración intermedios que no fueron debidamente registrados, lo que conduce a la obtención de un intervalo aproximadamente regular (Guerreiro and Lizarazu 2010;Kawamura 1927;Pohl 1991). Siguiendo estos pasos fue posible reconstruir la historia de floraciones masivas de 16 especies de bambúes leñosos nativos de la Argentina, desde el siglo XIX hasta nuestros días y, así, estimar la duración del ciclo de vida de cada especie.…”

R��.Los bambúes pertenecen a la familia de los pastos (o Poaceae). Existen 1698 especies de bambúes leñosos y herbáceos distribuidos alrededor del mundo en selvas y en bosques tropicales, subtropicales y templados. En nuestro país habitan cinco géneros y 23 especies de bambúes leñosos nativos. El aspecto más desconocido de los bambúes leñosos es su fenología reproductiva. Aunque se han descripto cuatro tipos de floración principales, las especies de bambúes más interesantes son las que poseen un patrón de floración masivo y cíclico luego de un período largo de crecimiento vegetativo. Dichos eventos de floración masiva ocurren a intervalos aproximadamente regulares, y luego de ellos, los individuos que florecen, mueren. El objetivo de esta revisión es proporcionar una muestra informativa del conocimiento actual de la floración de los bambúes, con énfasis en las especies nativas de la Argentina. Al día de hoy se conoce la duración aproximada del ciclo de vida de la mayoría de las especies de bambúes leñosos de nuestro país, sobre la base de una extensa búsqueda bibliográfica y de una revisión de las colecciones de los principales herbarios nacionales e internacionales. En la mayoría de las especies, los ciclos de vida medios son múltiplos de 15-16 años, y el ciclo de 30 años es el más habitual. En este trabajo se describen las principales hipótesis sobre las fuerzas evolutivas que conducen a los bambúes a florecer, producir semillas y morir de forma sincrónica. Asimismo, se discuten los factores ambientales, genéticos y la combinación de ambos, propuestos como posibles 'causas' de este atípico patrón de floración. Finalmente, se enumeran las consecuencias ambientales y sociales de este fenómeno.[Palabras clave: ciclos de vida, consecuencias ambientales y sociales, determinantes ambientales, determinantes genéticos, sincronía reproductiva] A��. Death by sexual reproduction: The (unsolved) case of bamboo flowering. Bamboos belong to the grass family (or Poaceae). There are 1698 bamboo species distributed around the world in tropical, subtropical and temperate jungles and forests. In our country, there are five native genera that comprise 23 species. The least known characteristic of the woody bamboos is their flowering phenology. Four main types of flowering pa�erns have been described. However, the most interesting are those bamboo species that show a massive and cyclical flowering pa�ern, after a long period of vegetative growth. Such mass flowering events occur at roughly regular intervals and are followed by the death of the flowering individuals. The goal of this review is to provide an informative sample of the current knowledge of bamboo flowering, with an emphasis on the species native to Argentina. Currently, the approximate duration of the life cycle of most woody bamboo species in our country is known, based on a review of the collections of the most important national and international herbaria and an extensive bibliographic search. In most species, the average life cycles are multiples of 15-16 ...

Indonesia is a mega biodiversity country that has a very abundant diversity of plants. Plant diversity is inseparable from the role of insects that help to pollinate them. One such insect is the stingless bee (Tetragonula laeviceps). Tetragonula laeviceps is a bee that has a relatively small-to-medium body size and does not have a sting. Sumedang Regency is one of the regencies in the province of West Java; most of the Sumedang area consists of mountains and has protected forest areas with high biodiversity. The purpose of this study is to determine the biodiversity index of the vegetation around the Tetragonula laeviceps wild hives based on the composition and structure of the vegetation around the Tetragonula laeviceps bee hives. Data collection is carried out using the method of inventory and systematic checkered lines, with a total plot of 320. The results of the study show that the vegetation is composed of 229 plant species from 75 families. The most dominant vegetation type with the highest value of KR, FR, DR, and INP in all plant categories is the Aren tree species (Arenga pinnata). The Shannon–Wiener diversity index in this tree category is 3,186, the pole category is 3,107, the sapling category is 3,418, the seedling category is 3,657, and the understory plants category is 3,409, with all of the plant categories included in the high-diversity category.

Universitária km 3,5 Cidade Universitária, CEP: 75083-515, Anápolis GO, Brasil, gabriela-nc@hotmail.com ABSTRACT: One of the most efficient and effective alternatives according to specialists is bioenergy, obtained through biomass; however, are rare the scientific works that quantify the biomass of the several bamboo species in Brazilian territory. The objective of this work was to assess biomass production, absolute growth rate, and relative growth rate of Taquara plants (Bambusa tuldoides) irrigated and fertilized with potassium and zinc. The experimental design was randomized block, in a split-split-plot arrangement (2 × 2 × 4) with three replications, with two potassium rates in the plots (0 and 80 kg ha-1), two zinc sulphate rates in the subplots (0 and 5 kg ha-1), and four evaluation times in the sub-subplots (60, 90, 120 and 150 days after sprouting). Stem fresh weight, stem dry weight, stem water weight, stem dry weight to fresh weight ratio, absolute growth rate, and relative growth rate of the plants were also evaluated. The potassium e zinc fertilization increased the biomass production and growth rate of Taquara plants (Bambusa tuldoides). Keywords: Bambusa tuldoides, growth rate, nutrient, bioenergy. PRODUÇÃO DE BIOMASSA DO BAMBU TAQUARA IRRIGADO E ADUBADO COM POTÁSSIO E ZINCO RESUMO: Uma das alternativas mais eficientes e eficazes, segundo especialistas, é a bioenergia, obtida através da biomassa; no entanto, são raros os trabalhos científicos que quantificam a biomassa das diversas espécies de bambu em território brasileiro. O objetivo deste trabalho foi avaliar a produção de biomassa, a taxa de crescimento absoluto e a taxa de crescimento relativa do bambu Taquara (Bambusa tuldoides) irrigado e adubado com potássio e zinco. O delineamento experimental utilizado foi em blocos ao acaso, analisado em esquema de parcelas sub-subdividas 2 × 2 × 4, com três repetições, e as parcelas foram compostas por duas doses de potássio (0 e 80 kg ha-1), as subparcelas duas doses zinco (0 e 5 kg ha-1) e 4 épocas de avaliações (60, 90, 120 e 150 dias após a brotação). As variáveis avaliadas foram massa fresca (MF), massa seca (MS), massa de água (MA), razão massa seca/massa fresca (MS/MF), taxa de crescimento absoluto (TCA) e taxa de crescimento relativo (TCR). A adubação com potássio e zinco incrementa a produção de biomassa e a taxa de crescimento do bambu Taquara (Bambusa tuldoides). Palavras-chave: Bambusa tuldoides, taxa de crescimento, nutriente, bioenergia.
