Abstract: aspects of the morpho-anatomy of developing fruits and seeds of clusia parviflora are presented and discussed as a continuation of the study of these organs in clusiaceae. the fruit is a septifrage capsule; the suberized exocarp is derived from the external epidermis of the ovary. the mesocarp originates from the ovarian mesophyll and remains parenchymal in nature. the endocarp is derived from the internal epidermis of the ovary and the endocarp is derived from the inner ovary epidermis as well as from three to four adjacent subepidermal layers, with tangentially elongated cells which become lignified and contribute to fruit dehiscence. the ovules are anatropous, bitegmic, with an endothelium, and give rise to equally anatropous seeds. the exotesta has cells containing phenolic compounds. the exotegmen consists entirely of sclerids with anticlinal and undulating cell walls, while the rest of the tegmen collapses during maturation. the embryo is slightly curved and the hypocotyl-radicle axis is well developed, with two very small cotyledons. there seems to be uniformity in the genus clusia as regards the final number of layers in the mature seed coat, being evident the continuous lignified exotegmen and the hypocotylar embryo. it should be pointed out that the number of layers in the ovule integument can be used for diagnosis at the species level

Abstract: Clusia lanceolata Cambess é espécie arbustiva da Mata Atlantica. Caracteriza-se por ser dioica, com flores estaminadas e pistiladas grandes, vistosas, de colora o rosa, apresentando a parte interna vinácea. Foram descritos aspectos morfológicos e estruturais dos frutos e sementes dessa espécie, visando classificar corretamente o seu tipo de fruto e, também, confirmar a origem do apêndice carnoso que envolve as sementes. O material botanico utilizado constou de flores em antese e frutos, em quatro estádios de desenvolvimento, coletados de dois espécimes. Os estudos morfológicos e anat micos foram realizados segundo técnicas usuais. O fruto é cápsula septífraga, esférica, de colora o verde-avermelhado. O exocarpo é unisseriado; o mesocarpo parenquimático contém numerosos ductos secretores e feixes vasculares, de disposi o principalmente longitudinal. O endocarpo é derivado da epiderme interna do ovário e de três a quatro camadas subepidérmicas, cujas células alongam-se tangencialmente e a parede que delimita o lóculo sofre lignifica o. A abertura se faz pela sutura carpelar, por meio de uma faixa de células parenquimáticas de tamanho reduzido, que se bifurca em dire o aos lóculos no meio dos septos. Os óvulos anátropos bitegumentados, com endotélio e hipóstase, originam sementes também anátropas, exotégmicas e envolvidas por arilo de origem funicular e exostomal. O embri o é hipocotilar. Clusia lanceolata Cambess. is a shrub species native to the Atlantic Forest. The plant is dioecious, with large, showy, pink staminate and pistillate flowers that are wine-colored internally. The morphological and structural aspects of the fruits and seeds of this species are described here in order to correctly classify the fruit type and to determine the origin of the fleshy appendage that surrounds the seeds. The botanical material utilized here contained flowers in anthesis and fruits in four stages of development, and were collected from two different plants. The morphological and anatomical studies were performed according to traditional techniques. The fruit is a septifrage, spherical capsule with a reddish-green coloration. The exocarp is uniseriate; the parenchymatous mesocarp contains numerous secretory ducts and vascular bundles arranged in predominantly longitudinal positions. The endocarp is derived from the internal epidermis of the ovary and has from three to four subepidermal layers whose component cells are tangentially elongated, and the cell walls lining the locule become lignified. The fruits open by means of the carpelar suture, along a stand of

Abstract: leaf damage dynamics of drimys granadensis (winteraceae) and clusia multiflora (clusiaceae) seedlings in the high-andean forest. because of their slow growth, shade-tolerant species remain exposed to foliar damage long before reproductive age. foliar damage can be controlled through synchronous leaf production and specialized phytochemical strategies. in this study, the dynamics of foliar damage in different cohorts of seedlings were evaluated to determine if the high-andean species, clusia multiflora (clusiaceae) and drimys granadensis (winteraceae) appeal to the synchronous leaf production for controlling the herbivory and pathogenical damage, and to establish the possible relations between the healthy state, growth and mortality of seedlings. since a recently-emerged seedling could not supply the physiological costs of specialized strategies, we expected the highest synchronous leaf production in the youngest individuals, and differences between cohorts in foliar damage. four variables were measured to evaluate the health state along time, in three cohorts of seedlings: proportion of predated leaves (pp), proportion of healthy leaves (ps), proportion of leaves with symptoms of disease or punctual damage (pe) and growing (% increment of height). both species showed significant differences between periods in the proportion of healthy leaves, but there was not an effect of time-cohort interaction, therefore synchronic production of leaves was not a strategy more used for any particular cohort. foliar damage oscillated along time, fact that can be explained by the pulses of leaf production. however, this strategy had little efficiency to control the pathogen attack. in general, the unified behavior of all variables was affected by cohort, time, species an all the different interactions. association between growing and foliar damage were conditioned by climate. the highest mortality ocurred during the dry season, and one fourth of the d. granadensis deaths were caused

Abstract: Además de las estrategias fitoquímicas especializadas, las plantas pueden usar la producción sincrónica de hojas como un método de saciado de patógenos y herbívoros. Con el fin de determinar si las especies del bosque altoandino colombiano Clusia multiflora (Clusiaceae) y Drimys granadensis (Winteraceae) recurren a la producción sincrónica de hojas para controlar los efectos de la herbivoría y el ataque microbiano, y establecer que relación existe entre el estado de salud, el crecimiento y la mortalidad de plántulas, se evaluó la dinámica del da o foliar sobre diferentes cohortes. Dado que una plántula tolerante a la sombra recientemente emergida no puede suplir los costos fisiológicos de una estrategia especializada, se esperaba una alta sincronía en la producción de hojas en las plántulas más jóvenes, y diferencias en el da o foliar entre cohortes. Se midieron cuatro variables que evaluaban el estado de salud a lo largo del tiempo, en tres cohortes de plántulas: Proporción de hojas predadas, proporción de hojas sanas, proporción de hojas enfermas o con da o puntual y crecimiento. Ambas especies mostraron diferencias significativas entre épocas, en la proporción de hojas sanas; pero no hubo un efecto de la interacción tiempo-cohorte, por lo tanto la producción sincrónica de hojas no fue una estrategia más usada por alguna cohorte en particular. El da o foliar osciló a través del tiempo, lo cual puede ser explicado por los pulsos en la producción de hojas. Sin embargo, ésta estrategia tuvo poca eficiencia para controlar el ataque por patógenos. En general, el comportamiento unificado de todas las variables fue afectado por la cohorte, el tiempo, la especie y todas las diferentes interacciones. La relación entre crecimiento y da o foliar fue condicionado por el clima. La mayor mortalidad se dio durante la estación seca, y un cuarto de las muertes en D. granadensis fueron causadas por la acción conjunta de herbivoría y sequía. Los resultados sugieren que a pesar de la producción sincrónica de hojas en todas las cohortes, fue poca la eficiencia para controlar el da o foliar, ya que las medias de Ps estuvieron por debajo de 0.25 al final del seguimiento. Las diferencias en la dinámica del estado de salud entre especies podrían explicar parcialmente la coexistencia en el bosque altoandino.

Abstract: “Restinga” habitats present many stressful conditions for plant establishment. Clusia criuva occurs in these habitats, including dune fields, and for this reason the Parque Municipal das Dunas da Lagoa da Concei o, Florianópolis, Santa Catarina State, Brazil, was chosen as the area of study. In habitats where resources are scarce and abiotic conditions are severe, it is common to find positive interactions between plants (facilitation). Some studies suggest that bromeliad species facilitate other plants in “restinga”. The present study evaluated the population structure of C. criuva in two different habitats, i.e. in an internal dune and in dune slack, both with herbaceous and sub-shrub vegetation. The study described the differences in populations and the relationship between the occurrences of C. criuva and bromeliad species. The populations showed an aggregated pattern and low density in the two areas. On the dune slack, the plants were younger, and seemed to have colonized the area recently. In the dune itself, we observed a positive relation between C. criuva and the bromeliad species Vriesea friburgensis Mez var. paludosa (L. B. Smith) L. B. Smith. This relationship was not observed in the dune slack where the abiotic conditions are less restrictive in relation to the availability of water and nutrients.
